Multiple Choice
In a plant cell, which organelle stores water, nutrients (food), and waste products?
A
Nucleus
B
Mitochondrion
C
Golgi apparatus
D
Central vacuole
Verified step by step guidance1
Understand the function of each organelle listed: The nucleus controls cell activities and contains genetic material; the mitochondrion is the powerhouse of the cell, producing energy; the Golgi apparatus modifies and packages proteins and lipids.
Recall that in plant cells, there is a large organelle responsible for storing water, nutrients, and waste products, which helps maintain cell turgor pressure and overall cell structure.
Identify that this organelle is the central vacuole, a large, membrane-bound compartment that occupies most of the cell's volume in mature plant cells.
Recognize that the central vacuole stores water to keep the cell rigid, stores nutrients (food) for later use, and isolates waste products to protect the cell.
Conclude that among the options given, the central vacuole is the correct organelle that stores water, nutrients, and waste products in a plant cell.
