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 reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C6H12O6), which serves as an energy source for plants.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy required for the photosynthesis process, enabling plants to convert carbon dioxide and water into glucose.

Front

Why do plants appear green?

Back

Plants appear green because chlorophyll, the pigment responsible for photosynthesis, reflects green light and absorbs other wavelengths of light.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy for photosynthesis.

Front

What are chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that can produce their own food (e.g., plants), while heterotrophs are organisms that cannot and must consume other organisms for energy.
