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 is the primary function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that convert sunlight into energy through the process of photosynthesis.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily in the blue and red wavelengths, and is essential for photosynthesis.

Front

What are the main reactants of photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

Why do leaves appear green?

Back

Leaves appear green because chlorophyll reflects green light and absorbs other wavelengths of light for photosynthesis.

Front

What role does sunlight play in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

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

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the air through small openings in their leaves called stomata.

Front

What is the significance 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.
