What is photosynthesis?

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. It is essential for life on Earth as it produces oxygen and the organic compounds used as food.

What are the primary inputs for photosynthesis?

The primary inputs for photosynthesis are carbon dioxide (CO2), water (H2O), and light energy (sunlight).

What are the main outputs of photosynthesis?

The main outputs of photosynthesis are glucose (C6H{12}O6), which is a sugar used as food, and oxygen (O2), which is released into the atmosphere.

Where does photosynthesis primarily occur in plants?

Photosynthesis primarily occurs in the chloroplasts of plant cells, specifically in the mesophyll cells of leaves.

What are the two main stages of photosynthesis?

The two main stages of photosynthesis are:

1. Light-Dependent Reactions: Occur in the thylakoid membranes of chloroplasts and require light energy.
2. Light-Independent Reactions (Calvin Cycle): Occur in the stroma of chloroplasts and do not directly require light, using the energy produced in the light-dependent reactions to fix carbon dioxide.
