Photosynthesis Basics

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Front

Which organisms perform photosynthesis?

Back

Plants, algae, and some types of bacteria perform photosynthesis.

Front

What do plants produce during photosynthesis?

Back

Plants produce oxygen and glucose (a type of sugar) during photosynthesis.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a pigment in chloroplasts that absorbs energy from sunlight, giving plants their green color.

Front

What are the two main stages of photosynthesis?

Back

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

Front

Where do light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What happens during the light-independent reactions?

Back

During light-independent reactions, energy from ATP and NADPH is used to assemble glucose from carbon dioxide.

Front

What is C3 photosynthesis?

Back

C3 photosynthesis is the most common form, producing a three-carbon compound during the Calvin Cycle.

Front

What is C4 photosynthesis?

Back

C4 photosynthesis produces a four-carbon compound, allowing plants to thrive in low light or water conditions.
