Control Systems in Plants
Growth and control of plants is due to both internal
(chemical) regulators and external (environmental)
Together these regulators determine the growth of the plant
Respiration: overall exchange of gasses between atmosphere lungs and blood.
Cells need a continuous supply of oxygen
Respiratory medium: Source of Oxygen, atmosphere or water
Respiratory surface- where gas exchange occurs (lungs gills)
