Photosynthesis

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 is the role of chlorophyll in photosynthesis?

Back

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

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 equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What are the products of the light-dependent reactions?

Back

The products of the light-dependent reactions are ATP and NADPH.

Front

What is the stroma in a chloroplast?

Back

The stroma is the fluid-filled interior space of the chloroplast where the Calvin cycle takes place.

Front

What is the significance of the Calvin cycle?

Back

The Calvin cycle is significant because it uses ATP and NADPH from the light-dependent reactions to convert carbon dioxide into glucose.

Front

What do plants need for photosynthesis?

Back

Plants need light, carbon dioxide, and water for the process of photosynthesis.

Front

What is the ultimate source of energy for photosynthesis?

Back

The ultimate source of energy for photosynthesis is the sun.
