Question

1. what organelle allows plant cells to make their own food using sunlight?

nucleus
cell membrane
chloroplast
vacuole

1. what do both plant and animal cells have in common?

cell walls and chloroplasts
nucleus, cytoplasm, and cell membrane

Explanation:

Question 4

To determine the organelle that enables plant cells to make food via sunlight, we analyze each option:

• Nucleus: Manages cell activities (DNA storage), not photosynthesis.
• Cell membrane: Controls substance movement, not food production.
• Chloroplast: Contains chlorophyll, enabling photosynthesis (converting sunlight to food).
• Vacuole: Stores substances, not involved in photosynthesis.

To identify common structures in plant and animal cells:

• "Cell walls and chloroplasts": Unique to plant cells (animal cells lack these).
• "Nucleus, cytoplasm, and cell membrane": Both cell types have these (nucleus controls, cytoplasm holds organelles, cell membrane regulates transport).

Answer:

C. Chloroplast
