Photosynthesis Bio Honors

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-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in plants that absorbs light energy, primarily in the blue and red wavelengths, and reflects green light, which is why most plants appear green.

Front

What is the light-dependent stage of photosynthesis?

Back

The light-dependent stage occurs in the thylakoid membranes of chloroplasts, where sunlight is captured to produce ATP and NADPH, and oxygen is released as a byproduct.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle, also known as the light-independent stage, is the process in which carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is passive transport?

Back

Passive transport is the movement of particles across a cell membrane from an area of high concentration to an area of low concentration without the use of energy.

Front

What is active transport?

Back

Active transport is the movement of particles against their concentration gradient, from low to high concentration, requiring energy (ATP) to do so.

Front

What are the main products of the Calvin Cycle?

Back

The main products of the Calvin Cycle are glucose, ADP, and NADP+.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis, used in the Calvin Cycle to produce glucose.

Front

What happens to water during photosynthesis?

Back

Water is split during the light-dependent reactions to release oxygen and provide electrons for the electron transport chain.
