Question

identification of parenchyma,collenchyma and sclernchyma tissue in plants from prepared slides and drawing of their labeled diagram

Answer 1

Parenchyma cells have thin primary wallsand usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root.

Collenchyma cells have thin primary walls with some areas of secondary thickening. Collenchyma provides extra mechanical and structural support, particularly in regions of new growth.

Sclerenchyma cells have thick lignifiedsecondary walls and often die when mature. Sclerenchyma provides the main structural support to a plant.[1]
