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

Which organisms perform Photosynthesis?

Back

Only Autotrophs.

Front

What is the role of Chlorophyll in Photosynthesis?

Back

Chlorophyll is the pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

What is the ultimate original source of energy for living things?

Back

The Sun.

Front

Define Autotrophs.

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light or chemical energy.

Front

Define Heterotrophs.

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms or organic matter for energy.

Front

What are the main products of Photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the chemical equation for Photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is the function of stomata in plants?

Back

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

Front

What is the significance of light in Photosynthesis?

Back

Light provides the energy required to convert carbon dioxide and water into glucose and oxygen during photosynthesis.
