7.4 - 1 Introduction to 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 stored in glucose.

Front

What are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are sunlight, water, and carbon dioxide.

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light, which is used in photosynthesis.

Front

How does an increase in light affect photosynthesis?

Back

An increase in light typically increases the rate of photosynthesis, as more energy is available for the process.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily in the blue and red wavelengths, and 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 happens to carbon dioxide levels during photosynthesis?

Back

During photosynthesis, carbon dioxide levels decrease as it is used to produce glucose.

Front

What is the effect of temperature on photosynthesis?

Back

Temperature can affect the rate of photosynthesis; too low or too high temperatures can slow down or inhibit the process.
