Question

describe parenchyma with diagram

Answer 1

Parenchyma, in plants, tissuetypically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved inphotosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) andcollenchyma (living support tissues with irregular walls).Parenchyma makes up thechloroplast-laden mesophyll (internal layers) of leaves and thecortex (outer layers) and pith (innermost layers) of stems androots; it also forms the soft tissues offruits. Cells of this type are also contained in xylem and phloem as transfer cells and as the bundle sheaths that surround the vascular strands. Parenchyma tissue may be compact or have extensive spaces between the cells.

Answer 2

Answer:

parenchyma:-

A few layers of cell form the basic packing tissue and are present in cortex and pithe of stem and roots in the mesophyll of leaves .

characteristics:-

- simple living cell with little specialisation

- having thin cell wall

- cells are usually loosely packed with large space between them

function:-

- serve food storage tissue

- provide support to plant

- parenchyma of stem and root also contain nutrients and water
