Photosynthesis - Overview

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What are the inputs of photosynthesis?

Back

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

Front

What are the outputs of photosynthesis?

Back

The outputs of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is G3P in the context of photosynthesis?

Back

G3P (glyceraldehyde-3-phosphate) is a three-carbon sugar produced in the Calvin cycle, which can be used to form glucose and other carbohydrates.

Front

What is the significance of light-dependent reactions?

Back

Light-dependent reactions convert solar energy into chemical energy in the form of ATP and NADPH, which are used in the Calvin cycle.

Front

What is the function of thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light-dependent reactions of photosynthesis take place.
