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

Where does the Calvin Cycle take place?

Back

The Calvin Cycle takes place in the stroma of chloroplasts.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: CO₂ + light + H₂O → O₂ + Sugar.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.

Front

What is the primary function of chlorophyll?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to facilitate photosynthesis.

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?

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 and protons for the light-dependent reactions and is split to release oxygen.

Front

What is the significance of glucose produced in photosynthesis?

Back

Glucose serves as an energy source for plants and is used in cellular respiration, as well as a building block for growth.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through the stomata in their leaves.
