PLANT TISSUES In plants meristematic tissues are classified into
three types of permanent tissue.• Simple permanent tissue• Complex permanent tissue• Special or Secretary tissue Common types of simple permanent tissues are
parenchyma, Collenchyma, Sclerenchyma. Complex tissue is also known as vascular tissue.
Common types of complex tissue are Xylem and Pholem.
Parenchyma
Composed of cells with the simplest structureSeen in the soft parts of the plantHelps in photosynthesis and the storage of food
Collenchyma
Composed of cells that are thick only at the corners of the cell wallProvides flexibility and support to plant parts
Sclerenchyma
Composed of cells that are uniformed thick all over the wallProvides strength and support to plant parts
Xylem
Transports water and minerals absorbed by the roots to the leaves . Has thick cell walls and therefore provide support and strength to the plant.
Tubes formed from elongated cells
Phloem
Transports food synthesized in the leaves to various parts of the plant body.
Composed of tubular inter –connected cells.
