Question

Write difference between parenchyma and colenchyma in tabular form ?

Answer 1

Answer:

Parenchyma Cells

These are the living plant cells known to repair and heal and also to store food, forms a thin layer known as primary cell wall of the plant. They occur as a continuous mass, widely distributed from stems, roots to leaves and fruits

Generates other special cells and tissues

Isodiametric in shape, having thin cell walls hence experience pressure and force around the cells, therefore, cells increase its volume capacity to equalize all-over pressure on the cells

Cells composed of cellulose and hemicellulose

Show abundance in cell organelles such as – Golgi bodies, ribosomes, Chloroplast, Endoplasmic Reticulum, and other constituents such as pigments, fats, starch, proteins.

Collenchyma Cells

Known to render mechanical support to plants by protecting the delicate inner structure of plants

They have thick cell walls composed of cellulose, hemicellulose and pectin and are living cells. Cells comprise of prominent nucleus and organelles

It carries out storage of food, checks for the tearing of leaves, carry out photosynthesis. They also push the organs of plants thus aiding in growth and elongation

Difference Between Parenchyma and Collenchyma Cells

Listed below are some differences between these cells:

Parenchyma Cells Collenchyma Cells

What it means

Originate from ground and protoderm meristems Originate from pro-cambium. Epidermal layer of plants are composed of collenchyma cells

Location

Found in every delicate plant part Specifically found in leaves, stems and petioles

Cell type

Living and unspecialized cells Living and specialized cells

Shape of the cell

Isodiametric generally, may vary in shape Elongated cells

Cell wall

Present and thin-walled

Made of cellulose

Present, uneven cell wall

Made of pectin and hemicellulose

Intercellular spaces

Present between cells Less space present

Function

Food storage

Gaseous exchange

Photosynthesis

Renders mechanical support

Answer 2

Answer:

Hi mate

Good morning

Here is your answer

Parenchyma

Parenchyma is the most common type of unspecilalised simple tissue.

It is composed of collection of cells which are more or less isodiametric in shape with or without intercellular space. These are the living cells with active protoplast.

Collenchyma

Collenchyma The cells of this tissue are living cells with vacuolated protoplast.

The most important distinctive character of collenchyma is that either walls are unevenly thickened or these thickenings are confined to the corners of the cells. It is usually absent in monocot.
