Exploring Cells and Their Organelles

What is the main function of the cell membrane in both plant and animal cells?

• To control what enters and leaves the cell

• To make food for the cell

• To store water and nutrients

• To provide energy for the cell

Why do plant cells have a cell wall, but animal cells do not?

• To help plants move

• To give plants extra support and shape

• To help plants eat food

• To make plants grow faster

How does a microscope help scientists study cells?

• It makes cells larger so they can be seen

• It changes the color of cells

• It creates new cells

• It removes cell walls

If a plant cell did not have chloroplasts, what would most likely happen?

• The cell would not be able to make its own food

• The cell would not have a nucleus

• The cell would not have a cell wall

• The cell would not be able to divide

Imagine you are given two unknown cells. One has a cell wall and chloroplasts, and the other does not. Using your knowledge of cell structures, explain how you would identify which is a plant cell and which is an animal cell.

• The cell with a cell wall and chloroplasts is a plant cell; the one without is an animal cell.

• The cell with a cell wall and chloroplasts is an animal cell; the one without is a plant cell.

• Both are animal cells because they have cytoplasm.

• Both are plant cells because they have a nucleus.
