The organelle that occupies most space in a plant cell is the vacuole (Option B). It plays a crucial role in storing water, nutrients, and waste products, contributing to the cell's structural support and maintaining turgor pressure.
The vacuole, represented by option B, occupies the most space in a plant cell. This organelle serves multifunctional roles, acting as a storage unit for water, nutrients, and waste products. Its prominent size contributes significantly to maintaining turgor pressure, providing structural support to the cell.
Beyond storage, the vacuole also plays essential roles in detoxification, pigmentation, and cellular growth regulation. Its expansive presence exemplifies the distinctive feature of plant cells, distinguishing them from animal cells. The vacuole's dynamic functions underscore its vital contribution to plant cell physiology, ensuring optimal conditions for growth, development, and adaptation to environmental changes.
The complete question is:
Which cell organelle occupies most of the space in a plant cell?
A. Mitochondria
B. Vacuole
C. Nucleus
D. Endoplasmic reticulum
