cell lab powerpoint= cell lab analysis= 1a. The chloroplasts are moving. 1b. They are moving in the same direction and speed in each individual cell. Their direction differed between each individual cell. 1c. The chloroplasts get their locomotion from the energy from the sun. 2a. The cells almost look like bubbles with a cell wall, cell membrane, starch grains, and cytoplasm. 2b. There are no chloroplasts in the potato cells. 2c. The iodine is the color purple out of the bottle. It stains the potato cells black. 2d. There is starch in the potato cells because the iodine turned them black which shows starch is present. 2e. The potato grows in the ground which means the plant above the ground goes through photosynthesis with the sun's energy and sends it through the root to the potato. 3a. No nothing turned black or blue in the onion which means starch isn't present. 3b. Yes because the onion is grown underground also and there are no chloroplasts present which means the plant above it sends energy and food through the roots.

4a. Yes because you can see the outline of another layer of cells underneath the first layer in the picture above. 4b. No all the cells are around the same size but they all vary in size and shape. 4c. I see red color chromoplasts which are the pigments. 4d. The plastids in the tomato are called chromoplasts. 4e. The cell wall is thick cell walls and they are close together. 5a. The cell is white with a little bit of black and red. 5b. The cell is a circle shape. 5c. The cell walls in the pulp are much thinner than the cell walls of the skin. 5d. The differences of the cells walls are because the pulp is there to store things and the skin cell walls are there to protect the cell. 5e. The chromoplasts in the cell are much more spread out then the skin which has the chromoplasts clumped together. 5f. The intensity of the red color on the skin is because the chromoplasts are all bunched together in the cells very tightly. The pulp, however, has there chromplasts spread out more so it appears red because of the many layers of cells on top of eachother. 6a. The cell wall in the beet seems to be thin. 6b. There are no pigments present. 6c. The pigments are dispersed throughout the cytoplasm. 6d. It may be the same pigment as in the tomato but the difference is that the beet has it much more spread out. 7a. These cells don't possess a cell wall because only plant cells have cell walls. 7b. The cells seem to be very similar in shape but they are not all exactly alike. 7c. These cells possess a nucleus but not chloroplasts or a vacuole. Conlusion: 1. Four similarities between plant and animal cells are that the all have a nucleus, cell membrane, cytoplasm, and they all are not exactly alike but have a similar shape to the other cells. 2. The main structural differences between animal and plant cells are that plant cells have a cell wall, vacuole, and may have some sort of pigment to them. 3. Three ways cells from the same area are similar is their shape, size and the organelles inside of it. 4. The purpose of staining some of the cells was to be able to see some of the organelles better and also to see if starch was present in the potato. Teacher note: you should write your answers as if I do not know the question. I had to go back to look at what you were answering on a couple. Otherwise, you photos and labels are great. 95%
