Student Blog Post Assignment #10: Anthers and Stigmas and Styles, Oh My!

In the life of plants they have to fight for survival and the only way that their species can keep living is if they reproduce.The first step is the seed. The seed grows into a beautiful plant so when the plant is mature it has something called the stigma which is the female part which collects pollen. The object that is around the stigma is called the anther's. The anther's are the male part that make pollen. The pollen is plant sperm so when the pollen lands on the stigma it fertilizes the eggs that are inside of the stigma. The only reason this can  happen is because of angiosperm. Angiosperm is a fancy way of saying pollinated by animals. The only way they can reproduce is by the help of animals that are moving their pollen. This is why they are angiosperm pollinated plants.

This is a picture of the flower in full bloom.

 

There are the anther's with the stigma when you take the pedals of the flower.

 

This is the stigma which is in the middle of the flower.

 

This is another picture of the stigma when I cut it open to find the eggs. 

                                                                                                                              The last photo I took was the pollen. The pollen is the plants sperm which animals like bees

transfer the pollen to different plants.

Throughout a plants life, they need to survive, and the way their species can survive is if they reproduce or adapt to their surroundings. The first thing formed is the seed, then it will grow into a flower or a plant. If the plant is tall or fully grown it will have a stigma, the female part that collects pollen from other plants. The object around the stigma is the anthers. Anthers are the male part of the plant that produce pollen. The pollen is the plant's sperm. Angiosperm is why this reproduction is able to happen.

The biggest differences in the Brassica Oleracea plants are in the leaves because the leaves of different species have different shapes, sizes, colors and textures.  I would say that the greatest range of variation among the species was also in the leaves. For instance, broccoli has tiny leaves but kale has huge leaves and the leaves of different species are also different colors.  Long ago, when all the brassica plants were in the same area they probably all had the same traits. Then natural variations and mutations starting happening.Also, people started selecting them for selective breeding like artificial selection and that's when the genes started to change. Descendants started to pass different modifications and started changing which was called descent and modification.  Changes might have been caused by natural variation like droughts and bug swarms. Plants develop adaptations to these changes, which modifies their genes. Something that might affect plants are mutations like RNA getting copied wrong.

"Who wants to live a million years"

It took me five  generations to win the game it might've been because I was risking my populations survival

In the beginning I chose a cubby won and a longneck one and long legs I chose this because they are the main groups. The phenotype that let me survive was long neck and long legs. I think this is so because long necks and long legs have a predators from far and long legs can run from them.

yes because I think my population are greatly affected  by genetic drift. I saw evidence of  genetic drift wen I chose red necks as my life line. They quickly populated more then the other groups but  they wuornt strong enough to survive the virus.

Long necks and long legs seam to be the dominant alleles. I can tell because they were the survivors.

A: short legs fur
B:long legs no fur
C:long legs and strips
D:long neck

I would allow people to chose  more then tree phenotypes at the beginning of the game.  
          
  

A Matter Of Selection

 1.  The part of the Brassica oleracea that has exhibited the most variation is it's height and mass. That is the area where it has showed the most growth, because of the natural resources they get each day like; sunlight, water, and fertile soil from the ground. After all, the part(s) that made the biggest difference between one extreme and its opposite is the color of their leaves, petals, and stems. Compared to others, all the plants have different colors, and sizes because they have different phenotypes.

2. I think that there is many variability in the domestic forms of Brassica oleracea because of the descent of modification from their ancestors and the genes that have been passed down to them. Like some mutations are harmful, not all of the many mutations are harmful.

       The Brassica Oleracea plant is different from other plants because its a lot more colorful, taller, and bigger than most plants. The greatest range of Brassica Oleracea plants are broccoli. One of the most Brassica Oleracea plants that stay the same throughout the garden during the different seasons probably broccoli. The only thing that changes about broccoli is when you don’t maintain the broccoli it starts growing little yellow flowers.    

Gattaca essay

 "Jerome was engineered with everything needed to get into GATTACA….except the desire to do so."





This quote means that genetic engineering will not guarantee success. Jerome had the perfect genes to get into gattaca,but he didn't have the motivation to succeed.  The glass that Vincent was cleaning represented the barrier that he would have to cross to get into gattaca. Water was an obstacle because Vincent had a heart condition  which made swimming a challenge for him.  

Tampering with genetics is wrong because people have the right to have their one-of-a-kind child that represents their own DNA.  The consequence of tampering with DNA is that scientists might make a mistake and create an unwanted mutation also,people might use genetic engineering to create a powerful family of super-hero offspring try and gain power.


It is not a good solution to genetically modify trees because it can ruin the food chain. There also might be some negative effects less leave,bark falling,shorter life span,less seeds and nuts,There are many insects and birds that feed off the trees, that might start dying if they can't feed off the trees. This would effect the whole ecosystem.  

GATTACA Essay

GATTACA Essay 

        The movie GATTACA talks about  how to make people genetically perfect to get a good job. To get a good job you have to be valid. For this assignment I had to choose a quot, so I choose "Jerome was engineered with everything needed to get into GATTACA ....except the desire to do so."- Vincent . To me this quote means you have to breath just as bad as you want it, Jerome just didn't want to breath as bad as Vincent.

           The second thing I had to choose was a symbol. The symbol I choose was glass/water as invisible obstacles Vincent must overcome. For example: the custodian telling Vincent not to clean the glass too well OR the games of chicken in the ocean. To me this is a symbol of Vincent and hi brother play chicken in the ocean because his brother thought just because his brother is weaker than him it means his brother can’t win.

           This is why I think no one can genetically be perfect of just be born perfect because the unperfect are perfect in there own ways and some of the unperfect are a lot more perfect than the perfect and thats what I got from the movie GATTACA.     

Who Wants To Live A Million Years: Analysis Of A Natural Selection Simulation

1. I survived on the ninth time trying the game. I think it took me that long because the species needed time to adapt, but the changes around their environment changed way too fast for them to survive. And this game relates to real life species because they need to adapt really quickly, in order to survive.

2. Some phenotypes that I chose that made my species survive were ; long necks, bulky ones, and thin ones. These made me win a couple of times because I guess they survive better with these genes.

3.Will they be greatly affected by genetic drift? Um I think they would because they seem to get really affected by every little change.

4. The dominant ones were long necks, stripped, and bulky. The recessive types were short ones, thin, and the red-colored type. And I could tell because they adapted to their shelter really fast.

5. cold conditions; furry type. warm conditions; thin animals. predators; stripped green ones. new tall food source; tall genes.

6. Some improvements could be; to add more changes to the environment for the species to adapt to, add more than 1 predator and lastly, make more phenotypes for the species.

Hi my name is Pete Martinez, Im from San Jose California

i never used to garden or anything like that,my grandma used to grow tomatos in here back yard i used to help her wash them.

Blog Post #7: The Wonders of Biodiversity

In my story of the seed, the plant that I am using is Brassica oleracea. I can predict that his parents had purple and white stem because my plant has a shade of purple and white. That's why his parents might have had some combination of these traits.  Most of my plant's traits would have come from his dominant parent. My plant will likely make more seeds and pass on its traits on to the next generation of plants. Whether my plant's genetic offspring look like it depends on what is inherited from each of its parents.  They might look different because of genetic variation in the plant's gene pool that occurred over hundreds of years. The plant started with a common ancestor, but variation occurred as meiosis pairing took place over and over again. That would cause many different  forms of brassica oleracea from the same common ancestor.

Today i went to the garden and i saw that it is growing. There is sunflower growing beside my plant which is providing some shade. There are lots of new leaves, but there are also some holes in the leaves. Because it has new leaves, I know the plant has grown. This means the plant is making more new cells. The plant's cells are rapidly dividing through mitosis. Most of this growth occurs at the plant's roots because that is where the plant soaks up nutrients from the dirt. The plant is also growing through photosynthesis because it is collecting a lot of carbon dioxide from the cars in the parking lot and turning it into oxygen and carbohydrates. Photosynthesis happens mostly in the plant's leaves. Sunlight hits the leaves and turns it into food in the plant leaves. Because the plant is bigger, we can say that it is adding biomass.

Enzymes help my plant because they play an important part in photosynthesis. Carbon dioxide combines with certain enzymes to make the plant's carbohydrates. Enzymes are also involved in respiration and the formation of ATP. 

 

blog post #6 [ how does your garden change ]

1. Our groups' plant is growing and adding biomass because of the photosynthesis cycle it is going through, plus, its respiration level increases as the plant grows in biomass.

The plant is alive because if you don't water it, it will not grow and living things are affected by their surroundings.

blog post #4

1. Some abiotic factors that help with the survival of our plants are worms, to break down the soil. And butterflies / bees to transport honey and nutrients.
2. They are competing against the other plants in the garden, and I know that they are in competition because all the plants want to grow big.
3. The "loses" are the plants who aren't getting enough sun and water to survive, while on the other hand, the winners are the ones who're getting the most sunlight and water.
4. Some other interactions are the fact that some plants are in front others, so the ones that are in the front row are consuming all the sun.
5. It is primary succession because the soil was already broken down.

blog post #3

1. Ive noticed that our kale has been growing somewhat okay.
2. It relates to the water cycle because the plants absorb the water through their roots.
3. It relates to the carbon cycle because once they breathe in the oxygen they let out carbon into the air.

Garden Heroes#5

My plant is looking good. The proof that it is alive is that it is continuing to grow taller and wider. Plants are amazing because they start as seeds. The seeds then developed roots while we stored them in the classroom. When the roots got big, we put them in soil and kept them in the classroom. When I finally planted my plant, it was around 4 inches tall. Now three weeks later it is now around 11 inches tall. The leaves have gotten way bigger compared to when we first planted them. More proof that it is alive is that it has attracted a lot of insects. The insects are making holes in the plants. The plant is fighting for survival as the insects eat it for its nutrients. The butterflies, ants and other bugs are spending time around the plants. The bugs wouldn't be around the plant if it was dead because it wouldn't be beneficial for them.

Living things respond to and interact with their environment. My plant has already found a garden buddy because it growing closer and closer to the sunflower behind him. Sunflower and lettuce plants make good buddies because the sunflower provides shade which the lettuce plant likes. But sunflowers attract a lot of bugs so that may be hurting my plant. My plant contributes to the environment by being a source of food and oxygen. People need vegetable plants like cabbage and lettuce to eat and survive. People and all other organisms need the oxygen that the plants make.

                   Today we have picked kale seeds to grow in the garden. First we have gently opened the seed bag its important to open the bag carefully because if u don't the tiny seeds will fall everywhere. Secondly you damp a pice of paper towel and place the seeds on one side of the paper towel. Thirdly you want to fold the damp paper towel. Lastly you want place the seeds that are in the wet paper towel into a plastic bag. Over the weeks you want to check on your seeds. You want to check to see if you seeds have sprouted. Once your seeds have sprouted you can gently take your seeds off the damp paper towel. After you do that you may place your sprouted seeds into the dirt.
