MD: 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 chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

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 photosynthesis.

Front

What are stomata?

Back

Stomata are small openings on the underside of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit the plant.

Front

How many molecules of oxygen are produced for every six molecules of carbon dioxide used in photosynthesis?

Back

For every six molecules of carbon dioxide used, six molecules of oxygen are produced.

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial because it produces oxygen, which is essential for the survival of most living organisms, and it forms the base of the food chain.

Front

What factors can affect the rate of photosynthesis?

Back

The rate of photosynthesis can be affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis; it is split into hydrogen and oxygen, providing electrons and protons needed for the formation of glucose.
