Cell wall is secreted by:
Correct answer: D. Protoplasm
- A. Cell membrane
- B. Vacuole
- C. Cytoplasm
- D. Protoplasm
Explanation
The cell wall is synthesized and secreted by the protoplasm, which encompasses the cell's cytoplasm and nucleus. Within the protoplasm, organelles such as the endoplasmic reticulum and the Golgi apparatus are involved in the production and transportation of cell wall materials. The other options are incorrect because the cell membrane and vacuole do not contribute to cell wall formation, and while the cytoplasm holds the components necessary for cell function, it does not independently secrete the cell wall.

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.
