A plant cell and an animal cell are of the same size.
Which cell will have a larger vacuole? Give reasons.
The plant cell will have a larger vacuole. Plants are fixed in one place and need support to stay firm and upright. While the plant cell has a cell wall that provides rigidity and strength, the large vacuole helps maintain this rigidity and turgidity. Animal cells do not have a rigid cell wall and can change shape easily, so they do not require large vacuoles for structural support.
What assumptions are you making to answer the question above?
The assumptions made are that both the plant cell and the animal cell are typical, mature cells of their respective organisms, and they are functioning under normal, healthy conditions.
Explanation
The question contrasts plant and animal cell structures based on their functional needs. The provided context highlights that plants need support to stay firm and upright, and plant cells have a cell wall for rigidity. Large vacuoles complement the cell wall by providing turgor pressure for firmness. Animal cells are flexible for locomotion and lack rigid walls, hence having smaller, temporary vacuoles. The assumption of maturity is necessary because immature plant cells (like meristematic cells) typically have small or no vacuoles.
