Final answer:
Photosynthesis in plants occurs in chloroplasts, not in mitochondria.
Step-by-step explanation:
The correct answer is d. photosynthesis occurs in mitochondria. Photosynthesis takes place in the chloroplasts of plant cells, specifically in specialized structures called thylakoids. This process converts light energy from the sun into chemical energy in the form of glucose. The chlorophyll pigment in the chloroplasts absorbs red and blue light, reflecting green light, which is why plants appear green.
