Question

unlike animal cells, plant cells have cell walls that make them rigid. which organelle, other than the cell wall, also plays a vital role in providing rigidity to plant cells? a nucleus b chloroplast c central vacuole d endoplasmic reticulum

Explanation:

The central vacuole in plant cells stores water and other substances. When it is full, it exerts turgor pressure against the cell wall, contributing to the rigidity of the plant cell. The nucleus controls cell - activities, chloroplasts are for photosynthesis, and the endoplasmic reticulum is involved in protein and lipid synthesis.

Answer:

C. Central vacuole
