4.4.1.1 Photosynthetic Reaction Flashcards
1
Q
Equation for representing photosynthesis (word and symbol equation):
A
- Carbon dioxide + water —> (light) glucose + oxygen
- 6CO2+ 6H2O → C6H12O6+ 6O2
2
Q
How are leaves adapted to maximise photosynthesis?
A
Large surface area
3
Q
Describe what takes place during photosynthesis:
A
- Light energy is absorbed by a green substance called chlorophyll which is found in chloroplasts in some plant cells and algae
- This energy is used by converting carbon dioxide (from the air) and water (from the solid) into glucose (sugar)
- Oxygen is released as a by-product
4
Q
Where does the energy for photosynthesis come from?
A
The Sun
5
Q
Photosynthesis:
A
an endothermic reaction in which energy is transferred from the environment to the chloroplasts by light
