Question

1. where are the two sites where photosynthesis occurs? mark all that apply stroma cristae matrix thylakoids show your work

Explanation:

Photosynthesis occurs in chloroplasts. The light-dependent reactions take place in thylakoids (membranous sacs), and the light-independent reactions (Calvin cycle) occur in the stroma (fluid inside chloroplasts). Cristae are mitochondrial structures, and matrix is the mitochondrial fluid—both unrelated to photosynthesis.

Answer:

stroma, thylakoids
