Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. [1] The presence of numerous sclereids form the cores of apples and produce the gritty texture of guavas .
The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. [ citation needed ] Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues ...
Sclerenchyma 6. Cortex 7. Epidermis. In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. [1] The cortex is composed mostly of large thin-walled parenchyma cells of the ground tissue system and shows little to no structural differentiation. [2]
Ground tissue usually consists mainly of parenchyma, collenchyma and sclerenchyma cells, and they surround vascular tissue. Ground tissue is important in aiding metabolic activities (eg. respiration, photosynthesis, transport, storage) as well as acting as structural support and forming new meristems. [7]
The term parenchyma is Neo-Latin from the Ancient Greek word παρέγχυμα parenchyma meaning 'visceral flesh', and from παρεγχεῖν parenkhein meaning 'to pour in' from παρα-para-'beside' + ἐν en-'in' + χεῖν khein 'to pour'.
