question 29 (1 point)
where do the light - independent reactions occur?
○ a in the cytoplasm
○ b in the stroma of the chloroplast
○ c in the thylakoid membranes
○ d in the mitochondria

Explanation:

Light - independent reactions (Calvin cycle) occur in the stroma of the chloroplast. The stroma is a fluid - filled space inside the chloroplast, outside the thylakoid membranes. The cytoplasm is the site for many general cellular processes but not the Calvin cycle. The thylakoid membranes are the site of light - dependent reactions. Mitochondria are the site of cellular respiration (not photosynthesis light - independent reactions).

Answer:

B. in the stroma of the chloroplast
