3. Plant cells can use energy from the sun to make food. Animal cells cannot. Which organelle is responsible for this difference between plant and animal cells?

Question

chloroplast

cell wall

central vacuole

plasma membrane

4. Which standard about plasma membranes is correct?
Plant cells have rigid plasma membranes

Animal cells have cell membranes instead of plasma membranes.

Plant cells have cell walls instead of plasma membranes

Both plant cells and animal cells have flexible plasma membranes

Answer 1

3. The organelle responsible for the ability of plant cells to use energy from the sun to make food is the chloroplast. Chloroplasts contain chlorophyll, which captures sunlight and allows the process of photosynthesis to occur.

4. The correct standard about plasma membranes is: Both plant cells and animal cells have flexible plasma membranes. While plant cells have a rigid cell wall in addition to their plasma membrane, both types of cells possess a plasma membrane that regulates what enters and exits the cell.
