HEY DEAR .
------------------------------------------
1.) OSMOSIS =) a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
2.) TRANSPIRATION =) Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
3.) GUTTATION =) Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface.
HOPE , IT HELPS .

Heya Dear !!
----------------
In higher plants water is absorbed through root hairs which are in contact with soil water and form a root hair zone a little behind the root tips Root hairs are tubular hair like prolongations of the cells of the epidermal layer (when epidermis bears root hairs it is also known as piliferous layer) of the roots.
The walls of root hairs are permeable and consist of pectic substances and cellulose which are strongly hydrophilic (water loving) in nature.
Root hairs contain vacuoles filled with cell sap.When roots elongate, the older hairs dieand new root hairs are developed so that they are in contact with fresh supplies of water in the soil.
Hope it Helps You☺
