In a typical plant cell, which organelle primarily stores water and helps maintain turgor pressure?
A
Golgi apparatus
B
Rough endoplasmic reticulum
C
Central vacuole
D
Mitochondrion
Verified step by step guidance1
Identify the organelles listed in the problem and recall their primary functions in a plant cell.
Understand that the Golgi apparatus is mainly involved in modifying, sorting, and packaging proteins and lipids, not water storage or turgor pressure.
Recall that the rough endoplasmic reticulum is primarily responsible for protein synthesis and has ribosomes attached, so it does not store water or maintain turgor pressure.
Recognize that the mitochondrion is the powerhouse of the cell, generating ATP through cellular respiration, and is not involved in water storage or turgor pressure.
Conclude that the central vacuole is the organelle that primarily stores water and helps maintain turgor pressure in plant cells by exerting outward pressure on the cell wall.
