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 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 photosynthesis process.

Front

What are stomata?

Back

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

Front

What is the light-dependent stage of photosynthesis?

Back

The light-dependent stage is the first part of photosynthesis where sunlight is captured and used to produce ATP and NADPH, and oxygen is released as a byproduct.

Front

What is the light-independent stage (Calvin Cycle) of photosynthesis?

Back

The light-independent stage, also known as the Calvin Cycle, is the second part of photosynthesis where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

Why do most plants appear green?

Back

Most plants appear green because chlorophyll reflects green light and absorbs other wavelengths of light, such as red and blue.

Front

What is the ultimate source of energy for photosynthesis?

Back

The ultimate source of energy for photosynthesis 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 the importance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen, which is essential for the survival of most living organisms, and it forms the base of the food chain.
