Describe the process of photosynthesis?
Light energy is absorbed by chlorophyll which is used to convert the carbon dioxide and water into sugar and glucose. As well as this oxygen is relaesed as a by -product.
2 of 12
What is gucose used for?
Respiration.
3 of 12
What can glucose be coverted into and what is it used for?
Starch for storage.
4 of 12
Is the starch later coverted back into glucose?
Yes.
5 of 12
What are the three limiting factors of photosynthesis?
Light intensity, carbon dioxide concentration and temperature.
6 of 12
Whit temperature too little is bad, too much is bad. What is the case with the other two limiting factors?
The more the better.
7 of 12
How can farmers prevent there being limiting factors?
Greenhouses.
8 of 12
How do greenhouses make carabon dioxide?
Parrifin heaters.
9 of 12
How do greenhouses control the temperature?
Heaters in the winter and coolers in the summer.
10 of 12
How do mainatin and increase light intensity?
Glass to let sunlight through in the dau and artificial light at night.
11 of 12
Apart from respiration and for storage, what can glucose be used for?
Making cell walls (turned in to cellulose which strengthens cell wall) and for making proteins by joining with nitrate ions to make amino acids.
