photosintesis
requirements of photosintesis
the ability of light
the presence of a pigment that absorb light
a supply of carbon dioxide and water
a temperature suitable for enzyme activity
factors
if one of these factors is in short supply the photosintesis would be less maximun
limiting factors
controls the rate of the overall proses
variates depending te time
factors of photosintesis
charbon dioxide
water
temperature
chlorophil
ability of light
provides energy
absortion of light
affects the enzyme activities
major influence on the rate of photosinesis
closes the stoma
plants and minerals
used to generate food molecules
plants absorbes minerals from de soil
minaras in soil
minerals are taken out of the soil to the plant
natural fertillisers
depends on he type of rock and the descompotion of animal and plants
products of photosintesis
oxidation
condensation
the food that the plant produce can be consumed by eavry organizm
reduction
plants manufacture their one food
problems with fertilizers
exesive fertilizers generate problems on eutrophication
water becomes oxigen defitient
fertilizers end in lakes, rivers
gloucouse + oxigen = carbon dioxide + water
