Photosynthesis

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 (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 from the sun, which is essential for the process of photosynthesis.

Front

What are the reactants needed for photosynthesis?

Back

The reactants needed for photosynthesis are carbon dioxide, water, and light energy.

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 significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

What is the equation for photosynthesis?

Back

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

Front

What environmental conditions affect the rate of photosynthesis?

Back

The rate of photosynthesis can be affected by factors such as light intensity, carbon dioxide concentration, temperature, and the availability of water.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis and is used to provide electrons and protons for the formation of glucose.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may become limiting.
