Why is it important that all cells have a cell membrane?

• It supports the cell wall.

• It controls all cellular functions.

• It is responsible for making DNA for the cell.

• It is the protective barrier that encloses the cell.

How do mitochondria make energy available to plant and animal cells?

• They use oxygen to turn food into usable energy.

• They use chlorophyll from sunlight to create food.

• They use particles found in the cytoplasm to create food.

• They spin quickly around in the cytoplasm to produce energy.

What function do the cell wall and cell membrane perform in a plant cell?

• They release energy for the cell.

• They make proteins for the cell.

• They maintain homeostasis for the cell.

• They create a protective boundary for the cell.

What would a plant cell be unable to do when a vacuole is damaged?

• The cell would be unable to store water.

• The cell would be unable to make proteins.

• The cell would be unable to make its own food.

Which statement describes the primary function of the chloroplasts in a plant cell?

• They capture light energy from the sun and use it, along with water and oxygen, to produce sugars for food.

• They release light energy from the leaves and use it, along with water and oxygen, to produce sugars for food.

• They capture light energy from the sun and use it, along with water and carbon dioxide, to produce sugars for food.

• They release light energy from the leaves and use it, along with water and carbon dioxide, to produce sugars for food.

Why do the lysosomes in an animal cell contain chemicals?

• They keep fungi out of the cell cytoplasm.

• They give off signals that attract food to the cell.

• They break down the nutrients brought into the cell.

• They dilute collected water so it can pass through the cell membrane.
