The correct answer is: D.Cell membranes are found in animal and plant cells, while cell walls are not found in animal cells.

Here's the explanation of each option:

A.Cell membranes are found in eukaryotes, while cell walls are only found in prokaryotes: This statement is incorrect. Both eukaryotes (including plants, fungi, and some protists) and prokaryotes (bacteria and archaea) have cell walls, though the structure and composition differ. Cell membranes are present in all cells, both eukaryotic and prokaryotic.

B.Cell membranes are found in fungi and bacteria, while cell walls are found in bacteria only: This is incorrect. Both fungi and bacteria have cell walls, but the composition is different. Fungi have chitin in their cell walls, while bacteria have peptidoglycan. Animal cells do not have cell walls, but they do hav...
