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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the red and blue wavelengths, to facilitate the process of photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What are the reactants needed for photosynthesis?

Back

The reactants needed for photosynthesis are carbon dioxide, water, and light energy.

Front

Why are plants called producers?

Back

Plants are called producers because they can make their own food through the process of photosynthesis.

Front

What happens to water and carbon dioxide during photosynthesis?

Back

During photosynthesis, the atoms in water and carbon dioxide rearrange to form glucose and oxygen.

Front

What is a heterotroph?

Back

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

Front

What is the significance of light in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

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

Front

What is the role of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere as a result of the splitting of water molecules.
