Question

where in plant cells are the energy - absorbing molecules for photosynthesis located?
a nucleus
b chloroplasts
c mitochondria
d cell membrane

Explanation:

To solve this, we analyze each option:

• Option A (nucleus): The nucleus stores genetic material, not for photosynthesis energy absorption.
• Option B (chloroplasts): Chloroplasts contain chlorophyll (energy - absorbing pigment) and are the site of photosynthesis.
• Option C (mitochondria): Mitochondria are for cellular respiration (energy release), not photosynthesis.
• Option D (cell membrane): The cell membrane regulates substance transport, not photosynthesis energy absorption.

Answer:

B. chloroplasts
