2.5.Photosynthesis

Front

What is photosynthesis?

Back

The process in which a cell captures energy in sunlight and uses it to make food.

Front

What are heterotrophs?

Back

Organisms that cannot produce their own food and must consume other organisms for energy; they are consumers.

Front

What is the source of energy for photosynthesis?

Back

Sunlight.

Front

What is chlorophyll?

Back

A green pigment found in plants that absorbs light energy for photosynthesis.

Front

What are stomata?

Back

Small openings on the surface of leaves that allow carbon dioxide to enter and oxygen to exit.

Front

What is the role of water in photosynthesis?

Back

Water is split into hydrogen and oxygen during the light-dependent reactions.

Front

What is glucose?

Back

A simple sugar produced during photosynthesis that serves as an energy source for plants.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is the importance of oxygen in photosynthesis?

Back

Oxygen is released as a byproduct during the light-dependent reactions of photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin cycle (light-independent reactions).
