In desert plants, rate of water loss gets reduced due to the presence of :-
Cuticle are protective, hydrophobic waxy covering produced by epidermal cells of leaves, young shoots and other aerial parts. It minimises the water loss through transpiration (with the help of stomata) and also reduces pathogen entry. Lignin hardens the cell wall and provides flexibilty, tensile and compressional strength to the cell wall. Suberin is present in cork cells and makes the cell impervious to water.
A long tree has several branches. The tissue that helps in the side way conduction of water in the branches is :-
Xylem vessels are very long tube-like structures formed by a row of cells placed end to end. The transverse wails between these cells are partially or completely dissolved to form continous water channels.
If the tip of sugarcane plant is removed from the field, even then it keeps on growing in length. It is due to the presence of :-
Intercalary meristems are present in stems at the base of nodes and leaf blades. Cells of such meristems can divide and form new cells.
Sugarcane is a monocot plant, which possesses intercalary meristem at the nodes.
Hence, if the tip of the sugarcane is removed then it can still grow using the intercalary meristem present at nodes.
