A group of cells that are specialized to perform a particular function forms a tissue.

1. Plant tissues
Plants do not move, i.e., they are stationary.
Most of the tissues they have are supportive, which provides them with structural strength.
Most of these tissues are dead, as they can provide better mechanical strength than the live ones, and need less maintenance.
Some of the plant tissues keep on dividing throughout the plant life. These tissues are localised in certain regions.
