Where does photosynthesis take place?
Correct answer
C
Rationale
The correct answer is C: Chloroplast. Photosynthesis takes place in the chloroplast, specifically in the thylakoid membranes where the light-dependent reactions occur, and in the stroma where the light-independent reactions (Calvin cycle) take place. The chloroplast contains chlorophyll, the pigment responsible for capturing light energy needed for photosynthesis.
Explanation for why the other choices are incorrect:
A: Endoplasmic reticulum - The endoplasmic reticulum is involved in protein and lipid synthesis, not in photosynthesis.
B: Mitochondrion - Mitochondria are responsible for cellular respiration, not photosynthesis.
D: Golgi apparatus - The Golgi apparatus is involved in processing and packaging proteins for secretion, not in photosynthesis.
In summary, the correct answer is C (Chloroplast) because it is the organelle where photosynthesis occurs due to the presence of chlorophyll and the necessary enzymes for the light-dependent and
