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

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the main pigment involved in photosynthesis?

Back

The main pigment involved in photosynthesis is chlorophyll.

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

What is produced during the light-dependent reactions of photosynthesis?

Back

During the light-dependent reactions, oxygen, ATP, and NADPH are produced.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight and converts it into chemical energy during photosynthesis.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide and water.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the air through small openings in their leaves called stomata.

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.
