In biology, tissue is a cellular organisational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

The English word "tissue" is derived from the French word "tissu", meaning that something that is "woven", from the verb tisser, "to weave".
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue.

Epidermis - Cells forming the outer surface of the leaves and of the young plant body.
Vascular tissue - The primary components of vascular tissue are the xylem and phloem. These transport fluids and nutrients internally.
Ground tissue - Ground tissue is less differentiated than other tissues. Ground tissue manufactures nutrients by photosynthesis and stores reserve nutrients.
Plant tissues can also be divided differently into two types:
Meristematic tissues
Permanent tissues.
