The capsid of a virus protects the virus from the external environment What structure is this similar to in a plant cell? A. Cell wall
B. Cell membrane
C. Vacuole
D. Ribosome

The answer would be the cell wall

Explanation:

B is not correct because a cell membrane is a semipermeable membrane surrounding the cytoplasm of a cell.

C is wrong too because a Vacuole is a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.

And D is false because a ribosome is a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.

i think that it is plants
