The correct answer is: D.Plant cells have cell walls.

Explanation:

Plant cells have a cell wall made of cellulose, which provides structural support, protection, and helps maintain the shape of the cell. Animal cells do not have a cell wall; instead, they only have a cell membrane.

Why the other options are incorrect:

A.Plant cells have cell membranes: Both plant and animal cells have cell membranes. This is not a distinguishing feature between them.
