Photosynthesis
Photosynthesis
1 of 11
What is the equation for photosynthesis?
Carbon Dioxide + water -> Glucose + Oxygen with light energy
2 of 11
What absorbs light energy in plant cells and algae?
During photosynthesis light energy is absorbed by a green substance called chlorophyll, found in chloroplasts
3 of 11
How is light energy used by plants and algae?
Used by converting carbon dioxide (from air) and water (from soil) into sugar (glucose)
4 of 11
What is a by-product of photosynthesis?
Oxygen
5 of 11
What 3 factors may limit the rate off photosynthesis?
1- shortage of light 2- low temperature 3- shortage of carbon dioxide
6 of 11
...... and the availibility of ....... interact and in practice any one of them may be the factor that ....... photosynthesis?
Light, Temperature and the availability of carbon dioxide interact and in practice any one of them may be the factor that limits photosynesis
7 of 11
How do gardeners and farmers use our knowledge of limiting factors?
-Maximise rate of photosynthesis, increase yield, and profit, By controlling conditions inside greenhouses and polytunnels 1-hight light intensity 2-Optimum temperature 3- optimum CO2 concertration OR Hydroponics
8 of 11
The ..... produced in photosynesis may be converted into soluble ...... for storage. Plant cells use some of the glucose produced during photosynthesis for ....?
The glucose produced in photosynthesis may be converted into soluble starch for storage. plant cells use some of the glucose produced during photosynthesis for respiration.
9 of 11
Describe 3 ways plants and algae use glucose?
1- Produce fat or oil for storage 2- to produce cellulose, which strengthens the cell wall 3- To produce proteins
10 of 11
What do plants need to make proteins?
The produce proteins, plants also use nitrate ions that are absorbed from the soil
