Permanent Tissue
Permanent Tissue The Permanent tissues develop from apical meristem. They lose the power of cell division either permanently or temporarily. They are classified into two types: Simple permanent tissues. Complex permanent tissues
Simple Permanent Tissues
Simple Permanent Tissues Simple tissues are composed of one type of cells only. The cells are structurally and functionally similar. It is of three types. Parenchyma Collenchyma Sclerenchyma
Parenchyma
Parenchyma Parenchyma is generally present in all organs of the plant. It forms the ground tissue in a plant. Parenchyma is a living tissue and made up of thin walled cells. The cell wall is made up of cellulose. Parenchyma cells may be oval, polyhedral, cylindrical, irregular, elongated or armed. Parenchyma may store various types of materials like, water, air, ergastic substances. It is usually colourless.
The turgid parenchyma cells help in giving rigidity to the plant body. Partial conduction of water is also maintained through parenchymatous cells.
