Question

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

Explanation:

• Cell membrane: Controls substance entry/exit, not main for shape/support.
• Cell wall: Rigid structure outside cell membrane. Gives plant cells shape, supports, and protects from damage.
• Chloroplast: Site of photosynthesis (converts light to energy), no role in shape/support.
• Vacuole: Stores substances (e.g., water, nutrients), helps with turgor pressure (minor shape role but not primary), not for protection like cell wall.

Answer:

cell wall
