What Is The Mechanism Of Excretion In Plants?
Transpiration Water is lost through transpiration or just used for maintaining the turgor in the cells. Vacuoles Plants cells have large vacuoles these can be used for substances. These may accumulate at the concentrations that lead to crystal formation in the vacuoles. Leaves Plants produce certain wastes of inorganic and organic nature, which are stored in the organs. The leaves are the prominent organs for this purpose, the falling of yellow leaves in autumn is the seasonal time for the plants to get rid of the accumulated wastes and because of this reason leaves are said to be excretophore. Branches and trunks Some trees deposit strange chemicals in their branches and trunks, especially in old xylem which is no longer used for water transport. This takes place in ebony which produces very black wood in centre. These are considers to be waste materials by plant physiologist.
