HORTICULTURE

Detailed explanation-1: -They are made up of thin cell wall made up of cellulose, hemicellulose. The cells of parenchyma are isodiametric or polyhedral in shape. They may be polygonal, oval, round or elongated.

Detailed explanation-2: -Parenchyma have thin walls of cellulose, whereas collenchyma have cell walls with thickened areas of additional cellulose. Sclerenchyma cells have lignified cell walls. They can be further categorised into narrow long cells (fibers) and cells of various other shapes (sclereids).

Detailed explanation-3: -Xylem Parenchyma: It is made up of thin-walled cells. The cell wall is made up of cellulose. Storage Parenchyma: These store various substances like water, starch, proteins etc. They act as a food and water reservoir.

Detailed explanation-4: -parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions.

Detailed explanation-5: -In the cell walls of higher plants, the tensile fibers are made from the polysaccharide cellulose, the most abundant organic macromolecule on Earth, tightly linked into a network by cross-linking glycans.
