Multiple Choice
What is the primary function of chloroplasts in plant cells?
A
Generate most cellular ATP through oxidative phosphorylation in the inner membrane
B
Store genetic information as chromosomal DNA and control cell division
C
Convert light energy into chemical energy by photosynthesis, producing sugars from and
D
Modify, sort, and package proteins for secretion and delivery to other organelles
Verified step by step guidance1
Identify the organelle in question: chloroplasts are specific to plant cells and some protists, and are involved in energy conversion processes.
Recall the main functions of the options given: mitochondria generate ATP through oxidative phosphorylation, the nucleus stores genetic information and controls cell division, and the Golgi apparatus modifies and packages proteins.
Understand that chloroplasts contain the pigment chlorophyll, which captures light energy necessary for photosynthesis.
Recognize that the primary function of chloroplasts is to convert light energy into chemical energy by synthesizing sugars from carbon dioxide (CO\_2) and water (H\_2O) through the process of photosynthesis.
Conclude that the correct function of chloroplasts is to perform photosynthesis, producing sugars that serve as energy sources for the plant.
