Multiple Choice
Which pair best describes the two main functions of chloroplasts in plant cells?
A
Store genetic information in DNA and control cell division through mitosis
B
Generate ATP primarily by oxidative phosphorylation and regulate apoptosis
C
Capture light energy to produce ATP and NADPH, and fix CO2 into carbohydrates via the Calvin cycle
D
Synthesize proteins on ribosomes and package them for secretion through the Golgi apparatus
Verified step by step guidance1
Identify the primary role of chloroplasts in plant cells, which is related to photosynthesis, the process by which plants convert light energy into chemical energy.
Understand that chloroplasts capture light energy to produce energy-rich molecules such as ATP and NADPH during the light-dependent reactions of photosynthesis.
Recognize that chloroplasts also fix carbon dioxide (CO2) into carbohydrates through the Calvin cycle, which is the light-independent reaction phase of photosynthesis.
Compare the given options to these functions: storing genetic information and controlling cell division are functions of the nucleus; generating ATP by oxidative phosphorylation and regulating apoptosis are functions of mitochondria; synthesizing proteins and packaging them is related to ribosomes and the Golgi apparatus.
Conclude that the correct description of chloroplast functions is capturing light energy to produce ATP and NADPH, and fixing CO2 into carbohydrates via the Calvin cycle.
