Answer:

Explanation:
The "light-free" or dark responses occur in the stroma of the chloroplasts. This is otherwise called the Calvin Cycle. Since these procedures can just occur in the chloroplast (a chlorophyll filled plastid in green plants), photosynthesis can just occur in green plants.

Explanation:
the chloroplast
Photosynthesis in plants can be described in four stages, which occur in specific parts of the chloroplast. In stage 1, light is absorbed by chlorophyll a molecules bound to reaction-center proteins in the thylakoid membrane.
The ATP is broken down to release energy which is used to combine hydrogen (from the light reactions) with carbon dioxide to produce sugar.
