This unit was about cells and their functions. It went in depth on the organelles, and different processes that cells do to carry out life. In Unit 3, we learned about all the organelles in a cell and their functions. It was also essential for us to understand diffusion and the processes of photosynthesis and cellular respiration. In a eukaryotic cell, there is a nucleus and it is larger than a prokaryotic cell. A prokaryotic cell is a lot smaller, about the size of an organelle of a eukaryote, and doesn't have a nucleus. Diffusion is a form of passive transport stating that molecules will tend to move from areas of high concentration to areas of low until they reach equilibrium.
In this unit, my strengths were knowing diffusion, distinguishing the types of cells, and knowing how light works and what it does for plants. My weaknesses were knowing all the different organelles in the cell and their functions because there are so many and they each do different things to help the cell live. A success that I had in Unit 3 was understanding diffusion and equilibrium. A setback would be completely understanding how photosynthesis and cellular respiration work.
From the labs we did in class and the vodcasts we watched at home, I learned a lot more about cells and what they do. In the Egg Diffusion Lab (http://kimisbioblog.blogspot.com/2015/10/egg-diffusion-lab-conclusion.html) we got to experiment with diffusion and osmosis. It demonstrated how cells shrink when put in a hypertonic solution because the solvent leaves the cell. When we looked at cells through a microscope lens, I saw what a cell actually looks like and how the organelles of a cell looked in proportion to the cell.
We also drew a more detailed description of how plants work. This activity really helped me understand everything that happens inside one thykaloid, one chloroplast, one mesophyll cell, one section of a leaf, and one plant. I liked how it got even more detailed for each picture and it helped me understand what happens where.
I would like to learn more about how cells became more complex and how they became multi-cellular organisms. I'd also like to learn more about the Krebs Cycle and light. An unanswered question that I have is about cellular respiration. We didn't really go much in depth and I'd like to know more about the steps of cellular respiration. I always wonder why plants are green; not because they have chlorophyll, but why aren't plants yellow or red or purple? Why green, what makes it so unique?

Your reflection has lots of details and its very good
