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 is the primary pigment involved in photosynthesis?

Back

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

Front

Why do most plants appear green?

Back

Most plants appear green because chlorophyll does not absorb green light; instead, it reflects it.

Front

What are the main reactants of photosynthesis?

Back

The main 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

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are stomata?

Back

Stomata are tiny pores on the underside of leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process to convert carbon dioxide and water into glucose and oxygen.

Front

What wavelengths of light does chlorophyll absorb most effectively?

Back

Chlorophyll absorbs light most effectively in the red and blue wavelengths.

Front

What is the equation for photosynthesis?

Back

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