Time: 2:30pm Weather: Sunny, breezy, 56*F I used Site Alpha for this assignment. The cells that I noted were plant cells and animal cells. The plant cells were present in the tree in Site Alpha and the grass. The animal cells were found in the squirrels and pigeons that frequent Site Alpha It is common knowledge that plant and animal cells have different cell walls. Plant cells have a rigid cell wall. The purpose for this is that it allows for tree trunks and leaves to feel the way that they do. Tree trunks are hard and protective and leaves are flexible and not easily broken or ripped. Animal cells do not have a cell wall, they just have a flexible cell membrane. This allows for them to have different shapes, while plant cells can only have one boxy shape. The boxy shape is important because thats what allows them to gross towards the sun so they can get their nutrients. My body responded to the environment by expressing goose bumps. I was a little chilly and windy so I felt cold. My body responded by giving me goose bumps. My pupils were also smaller than normal. It was very bright out so they did not need to dilate in order to let light in because theres was plenty of light.
