carbon dioxide + water —light—> glucose + oxygen
2
Q
What is the balanced symbol equation for photosynthesis?
A
6CO2 + 6H2O —–> C6H12O6 + 6O2
3
Q

4
Q
What are some limiting factors for photosynthesis?
A
- temperature
- carbon dioxide concentration
- light intensity
- chlorophyll concentration
5
Q
What is glucose used for in a plant?
A
Respiration
6
Q
What can glucose be changed into in a plant?
A
- insoluble starch, stored in the stem, leaves or roots
- fat or oil, which is also stored
- cellulose, to strengthen cell walls
- proteins, which are used for growth and for enzymes
7
Q
What do plants need, in addition to glucose, to make proteins?
A
Nitrate ions from the soil
8
Q
What is the inverse square law?
A
Doubling the distance between the lamp and pondweed will reduce the light intensity by a quarter
