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 blue and red wavelengths, to drive the photosynthesis process.

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 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

How does temperature affect photosynthesis?

Back

Temperature affects the rate of photosynthesis; generally, higher temperatures increase the rate up to a certain point, after which the rate declines due to enzyme denaturation.

Front

What is the effect of water availability on photosynthesis?

Back

Water is essential for photosynthesis; insufficient water can limit the process and reduce the rate of photosynthesis.

Front

What are stomata and their role in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they enable carbon dioxide to enter and oxygen to exit the plant.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis converts light energy into chemical energy, while cellular respiration converts that chemical energy into usable energy (ATP) for the plant.
