The cellular structure of a plant cell consists of which non-living component?
Correct answer: B. Cell wall
- A. Nucleus
- B. Cell wall
- C. Cell membrane
- D. All of these
Explanation
Option B is correct since, in a plant cell, the 'cell wall' is the only part that is non-living because it is an extracellular product and exists outside the living boundary of the cell i.e. the plasma membrane, and protects the cell besides providing it a definite shape.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
