Which feature is common to both plant and animal cells?

• A. Cell wall
• B. Cell membrane
• C. Chloroplasts
• D. Vacuoles

Answer: (B)

The cell membrane is a feature that is common to both plant and animal cells, serving as a protective barrier that controls the movement of substances in and out of the cell. It is made up of a phospholipid bilayer with embedded proteins, which play various roles in communication, transport, and structural support. Plant cells do have a rigid cell wall made of cellulose, which is not found in animal cells. Chloroplasts, responsible for photosynthesis, are present only in plant cells and some algae, while animal cells do not contain these organelles. Although both plant and animal cells may have vacuoles, they differ in size and function; plant cells typically have a large central vacuole, whereas animal cells may have smaller and more numerous vacuoles. Thus, the cell membrane serves as the shared feature that underlies the basic functionality of both cell types.
