Tissue is an ensamble of cell which has the same origin, function, and structure. Cell and tissues develope into mature form in a process know as differentiation. Based on the cell composition, tissue is distinguished into simple tissue and complex tissue. Simple tissue is a tissue composed of only one cell type and performing only one function, while complex tissue is a tissue composed of more than one cell and performing more than one functions.
Plant Tissue
In plant, the process of cell formation and differentiation begins form embryonic tissues called meristem. All plant tissues are devired from meristem.
Structure and Function of plant Tissue
In 1875, Sach divided plant tissue into tree tissue system as follows.
Plant tissue is composed of meristem, epidermis, cortex (parenchyma, colenchyma, and scelenchyma), vascular bundle (xylem and phloem), pith and pith rays.

Structure and Function of plant Tissue
In 1875, Sach divided plant tissue into tree tissue system as follows.
- Dermal tissue system which includes epidermis and peridrem tissue. The function ia as the outer protection layer of plant.
- Ground tissue system, which includes parenchyma, collenchymas, and sclerenchyma. The function is to form the base of plant body.
- Vascular tissue system, which includes xylem and phloem. The function is to conduct water and nutrition in plant.
Plant tissue is composed of meristem, epidermis, cortex (parenchyma, colenchyma, and scelenchyma), vascular bundle (xylem and phloem), pith and pith rays.
