Basics of Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose.

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

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What is the overall chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

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.

Front

How does light intensity affect the rate of photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may limit the process.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis and is split during the light-dependent reactions to release oxygen and provide electrons for the process.

Front

What happens to photosynthesis if carbon dioxide levels are low?

Back

If carbon dioxide levels are low, the rate of photosynthesis decreases, leading to reduced production of glucose.

Front

What is the function of roots in plants?

Back

Roots anchor the plant to the ground and absorb water and minerals from the soil.
