5C: Factors affecting Photosynthesis Flashcards
(5 cards)
1
Q
Light
A
- Plants need light to photosynthesise, therefore the amount/intensity of light can affect the rate of photosynthesis
- ‘Light Saturation Curve’: When the plant is saturated with light, preventing the rate of reaction from increasing anymore
2
Q
Light Colour
A
- Photosynthesis works fastest under red or purple light
- Works slowest under green light (Because chlorophyll reflects green light)
3
Q
Temperature
A
- Greatest when the environmental temperature matches the enzyme’s optimal temperature
4
Q
pH
A
- Photosynthesis occurs fastest within its enzymes’ optimal pH range
5
Q
A
