Explain briefly :(i) Capillary water (ii) Osmosis (iii) Aeroponics

1.	Explain briefly :(i) Capillary water (ii) Osmosis (iii) Aeroponics
Answer» (i) Capillary water is present in the spaces between the soil particles as a thin film. It is readily available to plants. It is held in the soil against the forces of gravity. (ii) Osmosis is the process in which water molecules move through a semipermeable membrane from their higher concentration to their lower concentration. (iii) In aeroponics, roots of plant are suspended into a plastic vessel and sprayed with oxygenated nutrient rich water. This technique allows the roots to absorb nutrients much faster causing rapid growth and more yield.
