Question

which of these provides structural support for a plant cell, and is not found in an animal cell? cell membrane glycocalyx cell wall cytoskeleton

Explanation:

To solve this, we analyze each option:

• Cell Membrane: Present in both plant and animal cells, controls movement in/out, not unique to plant for structure here.
• Glycocalyx: Mainly in animal cells (bacteria too), not plant cell's structural support.
• Cell Wall: Rigid layer in plant cells (and some microbes), provides structural support, absent in animal cells.
• Cytoskeleton: Present in both, helps with internal structure, not unique to plant for this support.

So the Cell Wall is the correct choice.

Answer:

C. Cell Wall
