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

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is released into the atmosphere, which is essential for the survival of aerobic organisms.

Front

How does light intensity affect the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis increases until it reaches a saturation point, beyond which it no longer increases.

Front

What is the effect of temperature on photosynthesis?

Back

Photosynthesis generally increases with temperature up to a certain point (optimal temperature), after which the rate decreases due to enzyme denaturation.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis, providing electrons and protons needed for the formation of glucose and oxygen.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.
