Rates of photosynthesis Flashcards
1
Q
Seasons plants grow best in
A
spring
summer
2
Q
How to increase rate of photosynthesis
A
- more carbon dioxide
- more light
- a warm temp
3
Q
Availability of light
A
- energy to drive photosynthesis
- more light, fast rate of photosynthesis is
4
Q
Amount of carbon dioxide
A
- raw materials required for photosynthesis
- more carbon dioxide, faster rate is
- often limiting factor
5
Q
A suitable temperature
A
- temp affects how quickly the enzymes work
- enzymes make reaction work
- as temp rises, rate increases
- if it becomes too hot, enzymes denature and photosynthesis stops
6
Q
Graph of light intensity / rate of photosynthesis
Limiting factors
A
light levels are limiting initially, the rate of photosynthesis then levels off. it increases at a higher temp, so at higher light levels, temp becomes the limiting factor.
