Photosynthesis Practice

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 primary pigment involved in photosynthesis?

Back

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

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is the significance of glucose in photosynthesis?

Back

Glucose serves as an energy source for plants and is used to build other organic compounds.

Front

What is the role of water in photosynthesis?

Back

Water is split into hydrogen and oxygen during the light-dependent reactions, providing electrons and protons for the process.

Front

What gas is released as a byproduct of photosynthesis?

Back

Oxygen (O₂) is released as a byproduct of photosynthesis.
