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.

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.

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.

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.
