Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy 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 and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy, such as animals.

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food from inorganic substances, using light or chemical energy, such as plants.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the survival of aerobic organisms, including humans.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles in plant cells where photosynthesis occurs, converting light energy into chemical energy.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin cycle) use ATP and NADPH to synthesize glucose.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and water availability.
