Question

where do the reactions of photosynthesis take place in autotrophs? mitochondria cytoplasm cell walls chloroplast

Explanation:

Photosynthesis is the process by which autotrophs (such as plants) convert light energy into chemical energy. Chloroplasts are the organelles in plant cells that contain chlorophyll, the pigment that captures light energy. The light - dependent reactions of photosynthesis occur in the thylakoid membranes within the chloroplasts, and the light - independent reactions (Calvin cycle) occur in the stroma of the chloroplasts. Mitochondria are involved in cellular respiration. The cytoplasm is the jelly - like substance within the cell where many general cellular processes occur but not the specific reactions of photosynthesis. Cell walls provide structural support to plant cells and are not involved in the chemical reactions of photosynthesis.

Answer:

Chloroplast
