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 organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are the organelles in plant cells that conduct photosynthesis.

Front

What are the main products of photosynthesis?

Back

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

Front

What are the reactants needed for photosynthesis?

Back

The reactants needed for photosynthesis are water (H2O) and carbon dioxide (CO2), along with sunlight.

Front

Why do plants need sunlight for photosynthesis?

Back

Plants need sunlight as it provides the energy required to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

How does photosynthesis benefit the environment?

Back

Photosynthesis benefits the environment by producing oxygen, which is essential for the survival of most living organisms, and by removing carbon dioxide from the atmosphere.

Front

What role do chlorophyll pigments play in photosynthesis?

Back

Chlorophyll pigments absorb light energy, primarily from the blue and red wavelengths, and convert it into chemical energy during photosynthesis.

Front

What is the difference between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose), while cellular respiration breaks down glucose to release energy for cellular activities.

Front

What is the significance of glucose produced in photosynthesis?

Back

Glucose produced in photosynthesis serves as an energy source for plants and is also used to synthesize other organic compounds.
