Photosynthesis

Front

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 reactions and the Calvin cycle.

Front

Where do the light reactions of photosynthesis take place?

Back

The light reactions take place in the thylakoid membranes of the chloroplasts.

Front

What is the primary function of the light reactions?

Back

The primary function of the light reactions is to convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is a molecule that carries energy within cells, used for various cellular processes.

Front

What is NADPH?

Back

NADPH (nicotinamide adenine dinucleotide phosphate) is a reducing agent that provides the high-energy electrons needed for the Calvin cycle.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of chemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in plants that absorbs light energy, primarily in the red and blue wavelengths, and is essential for photosynthesis.

Front

Which colors of light are most effective for photosynthesis?

Back

Red and blue light are the most effective for photosynthesis, while green light is mostly reflected.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of the light reactions of photosynthesis and is released into the atmosphere.
