What organelle is responsible for photosynthesis in plants??

Answer 1

The organelle responsible for photosynthesis in plants is the chloroplast.

Key Points About Chloroplasts:

1. Structure:
2. Chloroplasts contain a green pigment called chlorophyll, which captures sunlight.
3. They have an internal system of stacked membranes called thylakoids, organized into stacks called grana, where light-dependent reactions occur.
4. The surrounding fluid, called the stroma, is where the light-independent reactions (Calvin cycle) take place.
5. Function in Photosynthesis:
6. Light-Dependent Reactions: Occur in the thylakoids; sunlight is converted into chemical energy in the form of ATP and NADPH.
7. Calvin Cycle (Light-Independent Reactions): Occurs in the stroma; carbon dioxide is used to produce glucose using the ATP and NADPH generated earlier.
8. Importance:
9. Chloroplasts enable plants to convert solar energy into chemical energy, producing oxygen as a byproduct and forming the basis of most life on Earth by supplying energy to other organisms.
