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 autotrophs?

Back

Autotrophs are organisms that produce their own food from inorganic substances. Examples include plants, which use photosynthesis to create glucose.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

Which organelle is responsible for photosynthesis?

Back

The chloroplast is the organelle in plant cells that conducts photosynthesis, converting light energy into chemical energy.

Front

What do plants need for photosynthesis?

Back

Plants need carbon dioxide, water, and sunlight to perform photosynthesis.

Front

What is the ultimate source of energy for living things?

Back

The ultimate source of energy for living things is the sun.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is glucose and why is it important?

Back

Glucose is a simple sugar produced during photosynthesis that serves as an energy source for plants and other organisms.

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

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 limit the process.
