Question

the organelle responsible for carrying out photosynthesis is the:
mitochondrion.
nucleus.
chloroplast.
ribosome.
lysosome.

Explanation:

Chloroplasts are the organelles in plant cells and some algae that contain chlorophyll, which captures light energy to perform photosynthesis—the process of converting light energy into chemical energy (glucose). Mitochondria produce energy via cellular respiration, the nucleus stores genetic material, ribosomes synthesize proteins, and lysosomes break down waste; none of these carry out photosynthesis.

Answer:

chloroplast.
