for this quarter benchmark, we have been exploring the respiratory system of Humans, Lions, Frogs, and worms we talked about some similarities of-of these 4 living organisms such as how both frog and worm can breathe through there skin and human and lion breath through their nose
This quarter we had to do a project on one of the organ systems. The organ system we chose was the respiratory system. We did a museum on the lungs of a few animals. .The animal we chose to add to our museum was an African Lion. The other animals was a worm, frog, and human. I learned that not every animal breathes the same and we are really unique.
For our Q3 benchmark, we chose the circulatory system we had to analyze the circulatory system of a frog, worm, human and our animal of choice the African Bush Elephant. During this project, I learned how different animals blood moves through the body and what's different about their blood compared to other animals. A question that I still have is how come some animals are warm-blooded and others are cold blooded?
Looking back at my me and my group plants, given notice that they are different since the very beginning. During the course the plants had a very hard time sprouting and needed more seeds in order to grow for an odd reason. I remember the ST plant growing the fastest and wondering why, what was so different from the others? And what was affecting the plants each differently? Then I came to the conclusion that maybe it was because the lack of inconsistency of abiotic factors and each plant needed different things to sprout at a constant. During the course our plants sprouted late but when they did and we generated pollination things began to move more quickly and it was successful, I think this is what stood out to me most because it shows that everything in the environment has a purpose for example the bees pollinating.
Our F2 plants looked nothing like I nor my group mates predicted. The parent generation grew faster due to the fact that the F2 generation didn’t grow. We knew that there would be some possibilities as to why they didn't grow being not enough water, too much water, not enough sun light, too much sunlight, etc.
Genes have a greater indicator on how an organism will appear. Organisms look the way they do due to their parents genes. Organisms will receive half of their genes from their mother and the other half from their father. I wasn't very educate on plants but that they taken in Carbon Dioxide, and they go through photosynthesis, so basically knowing very little. I learned about how many factors affect plants in their growth, but like instead of just knowing that they are the factors, I learned why they are the factors.
The plants ended up being very different than our predictions. They didn't show much color but had grown and died faster than the F1 plants did. The one on the top is F1 and the one on the bottom is F2. Obviously F1 was able to thrive more than the F2 plants. I think the fact that we sometimes forgot about our plants that it lessened their ability to thrive where they were at. The genetics of the F1 plants is what gave the F2 plants their phenotype. The biggest indicator of how the plants were going to look at was to just remember how the F1 plants were crossbred and hope that we had completed the process correctly. The one thing that stood out to me throughout this whole process was how it was important to know how everything that's happening. Of course you have to know all of the steps, but I was shocked at how important it was to keep track of everything that had to be done and recorder every time we had the chance.
Did the F2 generation look like how you predicted them to look? It didn’t come out how I predicted they would’ve looked because they never grew.
Did the parent generation or the F2 generation grow faster? Yes the parent generation grew faster.
What might have hindered your plants' ability to thrive? I think the environment with them being so close to other plants may have hindered their growth.
How do genetics and the environment affect the phenotype of an organism? Genetics affect your base phenotype(default look) and the environment affects what it may look like based on what happens.
Which is a greater indicator of how an organism will look? I think in some cases genetics if the conditions are the same but if a mishap were to occur then the environment is most likely at fault.
A summary of what stood out to you during this course and why.
Over the course of this project we grew plants. We checked out the phenotype and genotype of each plant to see how well those plants would grow. I think overall I enjoyed seeing the growth of other group’s plants. I think this was outstanding how their plants were able to thrive and ours weren’t. With this happening it brought up questions such as “Why did this happen?” or “What are they doing differently”.
