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 (a sugar) and oxygen.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily in the blue and red wavelengths, and reflects green light.

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.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the significance of carbon dioxide in photosynthesis?

Back

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

Front

How does temperature affect photosynthesis?

Back

Temperature affects the enzymes involved in photosynthesis; too high or too low temperatures can slow down the process.

Front

What happens to the rate of photosynthesis if CO₂ concentration increases?

Back

The rate of photosynthesis generally increases with higher CO₂ concentrations, up to a certain point.

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 role of water in photosynthesis?

Back

Water is a reactant in photosynthesis; it is split to provide electrons and protons, and oxygen is released as a byproduct.
