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 do plants need for photosynthesis?

Back

Plants need sunlight, carbon dioxide, and water for photosynthesis.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily red and blue light, to drive the process of photosynthesis.

Front

Why do most plants appear green?

Back

Most plants appear green because chlorophyll reflects green light and absorbs other colors of light.

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose, which plants use for energy and growth.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen as a byproduct of photosynthesis.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food (e.g., plants), while heterotrophs are organisms that consume other organisms for food (e.g., animals).

Front

What is the equation for photosynthesis?

Back

The 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 because it produces oxygen and organic compounds that are the foundation of the food chain.

Front

What factors can affect the rate of photosynthesis?

Back

Factors that can affect the rate of photosynthesis include light intensity, carbon dioxide concentration, temperature, and water availability.
