Write difference between parenchyma and colenchyma in tabular form ?
Answers
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:
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.
