The chloroplasts did not appear to be moving.If they were to be moving the would all move in the same direction but at different rates of speed because they are all individual cells. There is no structure because the chloroplasts are scattered amoung the cells, they are different in length and size.

The cells were very bloche and wierdly shaped. There is no chloroplasts because potatos are grown in dirt.When the iodine leaves the bottle it is a reddish brown color but when it meets the potato it turns it black. There is starch because the potato cells turned black from the interaction of starch and iodine. The starch i likely to be found in the cell wall.

Onions do not react the same way to iodine as potatoes. My hypothesis was wrong, potatoes and onions both grow in the ground, but they booth have different reactions to iodine.

The tomato skin is not more than one cell think because when you look at it closley there dosent seem to be a overlay of cells. The shape of the cells mey vary, some are rectangular and some are triangular. Their size also varies. There is a pinkish grey color inside the cells. The tomato skin is more structured with cell walls much thicker than tomato pulp.

The color of the cells is a grayish brown color. The shape of the cell is jagged and crooked. The tomato plup is much different compared to the tomato skin it isnt formed to a specific shape or size where tomato pulp has some form. The chromoplasts are a grayish color in tomato pulp but in tomato skin it is more red because it isnt as watered down. The arrangement of chromoplasts if dirrerent.

The cell wall is think so that is can hold the cells pulp together. You can tell that there are pigmants because of the reddish purple color in the cell.
The pigmants are dispursed throughout the cytoplasm. It couldnt be the same because the pigmants were not dispursed throughout the cell.

Yes there is a cell wall but it is very thin.They dont all have the same shape it varies. The cells do process a nucleus but they dont process a vacuole or chloroplasts.



Conclusions

1. List at least 4 similarities between plant and animal cells:. Cell wall, lipids,cytoplasm,nucleus.
2. List the main structural differences observed between plant and animal cells:. Animal cells dont have chloroplasts unlike plant cells.
3. List three ways that cells taken from a specific area or structure in an organism are similar:. They are recieving the same ammount of energy, comming from the same place, and they have the same structure.
4. What is the purpose of staining the cells that you have observed in this activity:. To see the differences reacting to the same stain.
