FLASHCARD QUESTION

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. It occurs primarily in chloroplasts and involves light-dependent reactions and the Calvin Cycle.

FLASHCARD QUESTION

Front

What is chlorophyll?

Back

Chlorophyll is the green pigment in chloroplasts responsible for capturing light energy from the sun. It absorbs light most effectively in the blue and red wavelengths, reflecting green light.

FLASHCARD QUESTION

Front

What are chloroplasts?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place. They contain chlorophyll and other pigments, as well as structures necessary for light-dependent reactions and the Calvin Cycle.

FLASHCARD QUESTION

Front

What is light energy in photosynthesis?

Back

Light energy is the energy from the sun that drives photosynthesis. It is absorbed by chlorophyll and used to excite electrons, initiating the light-dependent reactions.

5.

FLASHCARD QUESTION

Front

What role does carbon dioxide play in photosynthesis?

Back

Carbon dioxide is absorbed from the atmosphere through stomata and used in the Calvin Cycle to form glucose during carbon fixation.

6.

FLASHCARD QUESTION

Front

What role does water play in photosynthesis?

Back

Water is a raw material for photosynthesis, absorbed by plant roots. It is split during the light-dependent reactions, producing oxygen and providing electrons and protons for energy production.

7.

FLASHCARD QUESTION

Front

What is oxygen's role in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere when water molecules are split during the light-dependent reactions.
