What primary structural difference distinguishes a plant cell from a typical animal cell when examined under a light microscope?
Answer and explanation
Correct answer: C. presence of a rigid cellulose cell wall and large central sap vacuole
- Step 1: Plant cells possess a rigid outer cellulose cell wall, plastids (chloroplasts), and a large permanent central vacuole. Step 2. Animal cells lack cell walls and large vacuoles, possessing only flexible plasma membranes and centrioles. Answer: presence of a rigid cellulose cell wall and large central sap vacuole. Why not the others: Both are eukaryotic with nuclear membranes; centrioles are typical of animal cells; both have plasma membranes.
