Photosynthesis Concepts and Processes

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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) 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 role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the sun, and reflects green light.

Front

In which organelle does photosynthesis occur?

Back

Photosynthesis occurs in the chloroplasts of eukaryotic cells.

Front

Why do plants appear green?

Back

Plants appear green because chlorophyll reflects green light and absorbs other wavelengths of light for photosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the respiration of most living organisms.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons needed for the formation of glucose.

Front

What is the importance of sunlight in photosynthesis?

Back

Sunlight provides the energy required to drive the chemical reactions of photosynthesis.

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).
