Photosynthesis

Front

What is photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is the light-dependent stage of photosynthesis?

Back

The light-dependent stage is the first part of photosynthesis where light energy is converted into chemical energy in the form of ATP and NADPH, occurring in the thylakoid membranes of chloroplasts.

Front

What is the light-independent stage (Calvin Cycle) of photosynthesis?

Back

The light-independent stage, also known as the Calvin Cycle, is the second part of photosynthesis where ATP and NADPH produced in the light-dependent stage are used to convert carbon dioxide into glucose.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a waste product of photosynthesis, released into the atmosphere, and is essential for the respiration of most living organisms.

Front

What gas do plants absorb during photosynthesis?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is NADPH and its role in photosynthesis?

Back

NADPH is a carrier molecule that stores energy and is used in the light-independent reactions (Calvin Cycle) to help convert carbon dioxide into glucose.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during the light-dependent reactions to release oxygen.
