Question

which of the following organelles provide structure and rigidity to a plant cell? (1 point)
∘ cell wall
∘ ribosome
∘ cell membrane
∘ chloroplast

Explanation:

To determine which organelle provides structure and rigidity to a plant cell, we analyze each option:

• Ribosome: Involved in protein synthesis, not structural support.
• Cell membrane: Controls substance movement, not primary for rigidity.
• Chloroplast: Involved in photosynthesis, not structural support.
• Cell wall: Made of cellulose, provides plant cells with structure and rigidity.

Answer:

A. cell wall
