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 source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

What gas do plants absorb during photosynthesis?

Back

Plants absorb carbon dioxide (CO2) from the atmosphere during photosynthesis.

Front

What is produced as a byproduct of photosynthesis?

Back

Oxygen (O2) is produced as a byproduct of photosynthesis.

Front

Where in the plant does photosynthesis primarily occur?

Back

Photosynthesis primarily occurs in the leaves of the plant.

Front

What are the main reactants in the photosynthesis equation?

Back

The main reactants in the photosynthesis equation are carbon dioxide (CO2) and water (H2O).

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What role do chlorophyll play in photosynthesis?

Back

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

Front

How do plants obtain water for photosynthesis?

Back

Plants obtain water for photosynthesis through their roots, which absorb water from the soil.

Front

What is the significance of photosynthesis to 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.
