fast plants

Posted by Maelyn Valentine in Biochemistry 2 Honors on

Throughout the journey of growing our plants it always felt as though the plants were growing very fast over the time but in my opinion it felt like parent seeds grew faster within time and that’s probably because I paid more attention to them than the others but still. I think we could’ve taken better care of them and they would’ve been healthier than before. With this course the thing that stood out to me the most was the way the plants grew under that little light in the back. How fast the progressed over time was really amazing

Studying the growth of plants.

​   Not all of our F2 generation looked like how I had predicted them to look because they looked like yellow and green leaves but a non-purple stem. Also towards the end, we stopped nurturing our fast plants like we were supposed to so it ended up looking dry and shriveled up. Also, the parent generation grew faster than the F2 generation. What really hindered our plants was the lack of watering that we should have done at least two to three times a week. Both genetic make-up and environmental influences, for example, height, weight and the color. Also, it might be growing accustomed to the artificial light, then the plant is in a tight space is making them look different from other plants which aren’t in a tight space and are receiving sunlight. The environment in which the organism might be inhabiting and how the way in which they are being treated. During the course of quarter four, I learned that the environment which a plant is inhabiting does have a big impact on the plant, affecting their growth. I acknowledged this first when we first began to nurture our plants to the point that they were green and more seeds were ready to be planted. Also when we stopped nurturing the plants and stop caring for them they began to wilt and went from being healthy green to a desert color and didn’t have little pods growing anymore.

Fast Plant Reflection

Posted by Jymaire Oconnor in Biochemistry 2 Honors on

When getting ready to conduct the second fast plant experiment I expected the offspring's to take after the parent with the dominant genes but the plants never made it so I was never able to see through to this assumption. When I first took the seeds there were 3 seeds with mini buds and I was surprised because I couldn't wrap my head around their growth due to them not being put in a proper environment yet, as well as not having their needs met (Sunlight/Water). From this if the growth of the F2 generation were successful I would say they would have had a quicker growth then their parents. Through this quick summary and the photo one can quickly realize the F2 generation plants did not make it and this maybe because heat and not enough water. When watering your plants you should look out for hot temperatures and you should do this because it evaporates the water which prevents your plant from taking in the water, which leads to your plant dying from thirst. When looking at growth it's not only you parents that affect your appearance, it's also the environment and this can be due to climate, diet, etc. The greater impact the environment has on your genes, the more suitable the environment, so for example civilians of Africa one thing we notice is their dark skin and this is due to the environment. Their dark skin helps protect them from taking any real damage from the suns strong UV Rays. With all that said something that stood out to me was how plants can not only go through photosynthesis but also cellular respiration. This stands out to me because the plants can create their own energy instead of taking it in from the sun.

I predicted that the F2 generation would look exactly like that is F1 generation. My prediction was wrong. There was slight differences between the to generation and the F1 generation. Personally I think that the F2 generation grew faster than the F1 generations. We got quicker results.The space of the plants were very small and when plants grow people usually transfer them into a different area to grow more and have more space. Also we were using a light to help them grow instead of sunlight so that can have a small effect on it.Depending on the environment the organism can get any mutation so that they can be Edison adapted to other environments for survival. Using a inheritance box to see what are the likelihood of the organism getting specific genes.Something that really stood out to me was that everything connects to matter what. Everything is always affected by something which causes like a domino effect for example prey and predator relationships.

Yes, our F2 generation looked how my group and I predicted them to look. Our F2 generation grew faster. The amount of water or sunlight that they were receiving could have hindered their growth. The genetics and environment have an affect on the phenotype of an organism because they both play a part in how they grow, how they look and etc. Genetics play a role with what color the plant will be, and other factors like that, but the environment has an affect on how the plants grow and thrive. Genetics have a greater indication of how the plant will most likely look. Overall what stood out to me during this course was how the genetics work with plants and other organisms and the role they play in not only humans.

For my F2 generation fast plants the seeds didn't grow but I predicted that they would have green stem and yellow leaves. Since we weren't able to produce F2 plants we observed other groups F2. Other groups F2 plants grew faster than our F1 generation plants. I'm not sure what factors hindered our F2 plants ability to thrive but for our F1 I think amount of water, light, and proximity to other plants could've hindered their ability to thrive. 

Genetics give from their parents affects an organism's phenotype. They get half from one parent and from the other and some features can be expressed while others are not some might mix a create something that's a blend of both. The environment can affect an organism's phenotype by causing some part of their physical appearance to adapt to it's surroundings. Genetics is a greater indicator of what an organism's phenotype will be.

​I noticed that 

  • We had only 3 baby seeds out of all of our pods

  • We adopted seeds from other groups

  • Added soil and fertilizer

  • Planted 2 (YG and B) baby seeds in each pod

  • Covered in more soil

  • Plants range in length from 3 ½ cm to 8 cm

  • 3 of the stems are becoming purples

  • 4 stems are a very light green

  • 13 of the leaves look rigid

  • 14 of the leaves are rounded

  • Biotic factors: other plants, bacteria, plants themselves

This is categorized like this because bacteria and plants are living organisms. The bacteria in the air could affect how our plants grow. Our peers’ plants could interfere with our plants because they could rub against each other. Our plants could rub against each other which could take off some leaves or flowers. Abiotic factors: artificial “sunlight”, temperature, soil, air we categorized the abiotic factors in this way because we are using are artificial “sunlight” to help our plants grow. It could be possible that the light could blow out. The temperature could change depending on the light or the room. The room could be hot or cold if the windows are open. The soil is a factor because we don’t know what’s included in the soil. Lastly the air, because it may be certain particles throughout the air that could affect the plants. We predicted that the F1 and F2 plants are going to be the phenotypes and genotypes for our baby plants. Since both of are parents were yellow green leaf, homozygous and heterozygous, their kids were more than likely going to produce yellow green leaf babies as well. This cycle continued on since we didn’t have a variation of the parents. One thing that could have effected our plant process was lack of light, because a lot of people in my class plants were dying because they did not have enough light to grow so they were drying out.

The procedure of this lab is to take parental seeds and observe each parental type which is homozygous with the phenotypes we will investigate. In order to complete our lab successfully everyone will need to have good background knowledge on genetics. The purpose of the procedure is to understand the basics of Mendelian genetics, the use of punnet squares, chi-square analysis of data, and the life cycle of diploid organisms useful in genetics studies. Something that stood out to me was how after week two our plants begin to grow and all have pods. Only plants NP gave birth. Things that would hinder our plants were the environment it was in and how we took care of it.  We did not water our plant everyday.

​The F2 generation looks like how we predicted them. We expected the colors to be different since we took the seeds from the first generation to plant the second generation. The F2 generation grew faster than the parent generation. The first generation barely grew at all. Some of the factors that could have hindered our plant's abilities to thrive is how much we watered them. The environment and ecosystem effects organisms chances of survival. For example, many organism exhibit traits such as camouflage to hide from predators or conceal themselves from their prey in order to capture them. However, environments can change due to a multitude of factors, some being caused by human activity (burning fossil fuels, deforestation, pollution) and natural disasters. For example, the rock pocket mice depended heavily on their sandy and light colored environment, which blends easily with their light-colored fur. This was an advantage that they held when it came to predators. Yet, years later a volcano erupted, turning the sandy environment into dark molten rock. Due to this, rock pocket mice, light fur turned into a disadvantage. They were easily exposed to their predators, leading to the decrease of their population. However, if you look at pocket mice today, they have dark colored fur. Though this happened, it wasn’t the environment that changed the pocket mice phenotype but a genetic mutation that happened at a pivotal moment for the pocket mice population. When hypothesizing what an organism will look like. The greater indicator would be looking at the genetic makeup of the organism. Something that stood out to me during this course is how many things can affect a plant ability to grow. For example, how much you water them and the soil. Another thing that stood out to me is how fast our F2 plant grew. Our F1 plant barely made it we had to keep re-planting since our soil and wick would dry out.

Throughout this project, it was an extremely complicated process ensuring that patience was key. It was extremely frustrating because the F2 generation actually didn’t look at all how we predicted. My group and I had tons of complications with the growth of our plants. The parent generation actually grew so I’d have to say that they grew much quicker than the F2. As previously mentioned the F2 generation had trouble growing so it did not grow at all. I believe the biggest issue to allowing our plants' ability to thrive is the amount of light as well as the amount of water that was being given to the plants. Often times during class periods we’d forget to check on our plants, as well as forgetting to water them. Your genes carry the instructions for the growth and development of your body. However, your phenotype is influenced during embryonic development and throughout your life by environmental factors. Environmental factors are many and varied and include diet, climate, illness, and stress. Something that stood out to me was the fact that the growth of our plants was never successful. I believe our plants were being affected and unable to grow due to the inadequate amount of light they were receiving while on the mat. Often times our group continuously found our plants in other areas that had no lighting. Even with the replanting effect, it still was an unsuccessful replant. With the continuous dryness of the plants, causing them to continuously die, the little growth that actually did happen was interesting to see. In an article titled, “Plant Growth Factors”, it states, “There are four primary factors that affect plant growth: light, water, temperature and nutrients. These four elements affect the plant's growth hormones, making the plant grow more quickly or more slowly.” This quote alone supports that the stimulating effects stopping the growth of our plants most likely had to do with the amount of light and water that they were receiving. Before the replanting of the plants, the plants actually had some growth. Although it was still groups with higher growth, we still had so many complications so it was interesting to see this little bit of growth. “With the continuous dryness of the plants, causing them to continuously die, the growth was interesting to see.” Nature News, Nature Publishing Group, www.nature.com/scitable/topicpage/environmental-influences-on-gene-expression-536.
