Question

which plant-cell organelle supports and maintains the cell’s shape and protects the cell from damage?
○ cell membrane
○ cell wall
○ chloroplast
○ vacuole

Explanation:

To solve this, we analyze each option:

• Cell membrane: Mainly controls substance entry/exit, not primary for shape support.
• Cell wall: In plant cells, it provides structural support, maintains shape, and protects from damage.
• Chloroplast: Involved in photosynthesis, not shape support.
• Vacuole: Stores substances, helps with turgor but not main shape/protection like cell wall.

Answer:

B. cell wall (assuming the options are labeled as A: cell membrane, B: cell wall, C: chloroplast, D: vacuole; adjust label as per original but the correct structure is the cell wall)
