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
