Happy Thanksgiving but before....

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 two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is produced during light-dependent reactions?

Back

ATP and NADPH are produced during light-dependent reactions.

Front

What is the Calvin cycle?

Back

The Calvin cycle, also known as light-independent reactions, is the stage of photosynthesis where carbon dioxide is converted into glucose using ATP and NADPH.

Front

How does photosynthesis impact the Earth's carbon cycle?

Back

Photosynthesis absorbs carbon dioxide from the atmosphere, helping to regulate the carbon cycle and reduce greenhouse gases.

Front

What factors affect the rate of photosynthesis?

Back

Factors affecting the rate of photosynthesis include light intensity, carbon dioxide concentration, temperature, and mineral nutrients.

Front

What is the significance of oxygen production in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, which is essential for the survival of aerobic organisms.

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 these products to synthesize glucose.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during light-dependent reactions to release oxygen.
