Question

1. identify and describe the two main parts of a chloroplast where photosynthesis occurs.
2. write the basic equation for photosynthesis using the names of the starting and final substances of the process.

Explanation:

Question 9

Chloroplasts have two main parts for photosynthesis. Thylakoids (with grana) are where light - dependent reactions occur. They have chlorophyll to capture light. The stroma is where light - independent (Calvin cycle) reactions occur. It has enzymes for carbon fixation.

Photosynthesis is a process where plants use carbon dioxide and water as starting substances. In the presence of light (and chlorophyll), they produce glucose and oxygen as the final substances.

Answer:

The two main parts are the thylakoids (and grana) and the stroma. The thylakoids (with grana) are the sites of light - dependent reactions (due to chlorophyll and electron transport chains). The stroma is the site of light - independent reactions (Calvin cycle, with enzymes for carbon fixation).
