Onion, Cheek, and Elodea Lab 1. What are the two types of cell we discussed? How would you classify onion, cheek, and Elodea cells? ans: The two types of cells we discussed is the plant cells, and animal cell. Onion, Cheek, and Elodea cells are all eukaryotic. Onion and Elodea cells are plant cells. Cheek cells are animal cells. They all have nuclei and cell membranes. 2. What is the shape of the onion cell, cheek cell, and Elodea cell? ans: The shape for onion cell and a elodea cell is a rectangular, square shape. The cheek cell is a circular shape. 3. What structures were present in the onion cell, cheek cell, and Elodea cell? Create a chart expressing the similarities and differences. ans: The structures that was present is…show more content…
8. Explain how viewing the cheek cell was different with and without iodine. ans: Viewing the cells was different without the iodine because iodine is a chemical substance that helps you see the cells better. 9. How did iodine help? Why do biologists use stain to study cells? With iodine you could see cells better and that is why biologists use stain to see cells. 10. Why would add salt solution to a plant cell to help see the cell membrane? ans: Plant cells have a stiff cell wall, the cell will not appear to shrivel as an animal cell will. Instead, the cell wall remains in place, but the contents of the cell, most noticeably the chloroplasts, seem to bunch up in the center of the cell, leaving an empty space between the cell contents and the cell wall. This separation of the cell membrane from the cell wall and subsequent concentration of the cell contents is due to loss of turgor pressure inside the membrane as water moves out of the cell, toward the higher salt concentration. This process is called plasmolysis. 11. What cell part did you find around plant cells that you did not find around cheek cells? In general, how does it affect the shape of the
