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 (C6H12O6) and oxygen (O2).

Front

What is the role of chlorophyll 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 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

How does light intensity affect the rate of photosynthesis?

Back

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

Front

What effect does temperature have on photosynthesis?

Back

Temperature affects the rate of photosynthesis; it generally increases with temperature up to an optimal point, after which it decreases due to enzyme denaturation.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis; it is absorbed by plants from the atmosphere and used to produce glucose.

Front

What happens to the rate of photosynthesis if a plant is enclosed in an air-proof bottle?

Back

The rate of photosynthesis will gradually slow down to zero because the carbon dioxide (CO2) will be used up and not replenished.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis and respiration are interconnected processes; photosynthesis produces glucose and oxygen, which are used in respiration to release 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).
