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 primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is produced during the light-dependent reactions?

Back

During the light-dependent reactions, ATP and NADPH are produced, along with oxygen as a byproduct.

Front

What is the role of water in photosynthesis?

Back

Water provides electrons that replace those lost by chlorophyll during the light-dependent reactions and is also a source of hydrogen ions.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the formula for photosynthesis?

Back

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

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the set of light-independent reactions in photosynthesis that convert carbon dioxide into glucose using ATP and NADPH.

Front

What is the significance of glucose in plants?

Back

Glucose serves as an energy source for plants and is used to build other carbohydrates, such as starch and cellulose.

Front

What are thylakoids?

Back

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