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 (sugar) using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are oxygen and sugar.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

Why do plants need sunlight for photosynthesis?

Back

Plants need sunlight as it provides the energy required to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What happens to the sugar produced during photosynthesis?

Back

The sugar produced during photosynthesis is either used immediately for energy, stored as starch for later use, or used to build other organic compounds.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the raw materials used in photosynthesis, which plants take in from the atmosphere to produce glucose and oxygen.

Front

What would happen to plants if they did not receive sunlight?

Back

If plants did not receive sunlight, they would be unable to perform photosynthesis, leading to a lack of energy and eventually causing the plants to die.

Front

What is the significance of oxygen produced in photosynthesis?

Back

Oxygen produced in photosynthesis is essential for the survival of most living organisms, as it is used in cellular respiration.

Front

How do plants absorb water for photosynthesis?

Back

Plants absorb water through their roots from the soil, which is then transported to the leaves where photosynthesis occurs.
