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 are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food from inorganic substances, using light or chemical energy. Examples include plants and algae.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and instead obtains it by consuming other organisms. Examples include animals and fungi.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy required for photosynthesis to occur, enabling plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy for photosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, and is essential for the respiration of most living organisms.

Front

How does temperature affect the rate of photosynthesis?

Back

Temperature affects enzyme activity; too low or too high temperatures can slow down the rate of photosynthesis.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis and is split during the light-dependent reactions to release oxygen and provide electrons.
