Where in a plant cell does photosynthesis take place?
In the chloroplasts
1 of 18
How is energy transferred to a plant from its environment for photosynthesis?
Energy is transferred to the chloroplasts from the environment by light
2 of 18
What is an endothermic reaction?
Energy is transferred from the environment
3 of 18
Name the products of photosynthesis
Carbon dioxide + Water - Glucose + Oxygen
4 of 18
What type of molecule is formed from combining glucose molecules with nitrate ions?
Glucose is combined with nitrate ions (absorbed from the soil) to make amino acids, which are then made into proteins
5 of 18
Why do plants store glucose as starch?
Glucose is turned into starch and stored in roots, stems and leaves, ready for use when photosynthesis isn’t happening (winter). Starch is insoluble, which makes it much better for storing than glucose

What effect would a low carbon dioxide concentration have on the rate of photosynthesis?
It will slow it down
7 of 18
What effect would a very low temperature have on the rate of photosynthesis?
It will slow down. The temperature has to be just right not above 45 Degrees Celsius
8 of 18
Give one way that the temperature can be decreased in a greenhouse
Shades and ventilation
9 of 18
Give one way that the level of carbon dioxide can be increased in a greenhouse
Use a paraffin heater

What is respiration?
Respiration is the process of transferring energy from glucose, which goes on in every cell
11 of 18
What is an exothermic reaction?
It transfers energy to the environment
12 of 18
Name the products of aerobic respiration
Glucose + Oxygen - Carbon dioxide + Water
13 of 18
What is produced by anaerobic respiration in muscle cells?
Glucose - Lactic acid
14 of 18
What is the word equation for anaerobic respiration in yeast cells?
Glucose - Ethanol + Carbon dioxide
15 of 18
Name 2 products of the food and drink industry that fermentation is needed for
Bread and Alcoholic drinks

What happens to muscles when they become fatigued?
Long periods of exercise also cause muscle fatigue- the muscles get tired and then stop contracting efficiently
17 of 18
In what organ is lactic acid converted back to glucose?
In the liver
