photosynthesis

what is photosynthesis

endothermic reaction that takes place in chloroplast which uses energy to change carbon dioxide and water into glucose and oxygen

1 of 13

what is the word and symbol equation of photosynthesis

carbon dioxide + water = GLUCOSE + OXYGEN

6CO^2 + 6H20 = C6H12O6 + 602

2 of 13

how do plants use glucose

- for respiration
- making cellulose
- making amino acids ( which are then made into protein )
- stored as oils or fats
- stored as starch ( ready for when photosynthesis isn't happening )

3 of 13

which are limiting factors that affect rate of photosynthesis

- light
- concentration of CO2
- temperature
- chlorophyll

4 of 13

equation for light intensity

1 / d^2

5 of 13

how to create ideal conditions for plants to grow in greenhouse gases

- in winter a farmer might use heater
- in winter they might use shades or ventilation
- artificial light after the suns gone down
- increase level of CO2 by using paraffin heater to heat greenhouse as paraffin burns it releases CO2
- keep plants enclose

6 of 13

what is respiration

the process of transferring energy from glucose , which goes on in every cell

7 of 13

how do organisms use energy transferred from respiration

- to build larger molecules from smaller ones
- in animals its used to allow muscle contraction
- in mammal and birds the energy is used to keep body temperature steady in cold temperature

8 of 13

what is metabolism

all the chemical reactions in one cell

9 of 13

how are lipid molecules made

1 glycerol and 3 fatty acids

10 of 13

how is excess protein used

its broken down in a reaction to produce urea which is then secreted in urine

11 of 13

what is aerobic respiration

respiration using oxygen its the most efficient way to transfer energy from glucose this occurs inside the mitochondria

12 of 13

word and symbol equation of aerobic respiration

glucose + oxygen = carbon dioxide + water

C6H1206 + 602 = 6CO2 + 6H20
