Differentiate between sclerenchyma and parenchyma tissues. Draw well labelled diagram.



PARENCHYMA TISSUES



SCLERENCHYMA TISSUES



● Parenchyma is made up of living cells.


● The cells are thin walled.


● Cell wall is made of cellulose.


● Parenchyma tissues store food and also help in photosynthesis.


● These tissues are found in soft parts of the plant such as mesophyll of leaves, etc.


● Cells of this tissue are loosely packed and have large intercellular spaces between them.



● Sclerenchyma is composed of dead cells.


● The cells are equally thickened.


● Cell wall of Sclerenchyma tissues are made of lignin.


● Sclerenchyma tissues provide mechanical strength, flexibility and elasticity to the plant.


● Sclerenchyma tissues are found in roots, veins of leaves, etc.


● Cells of this tissue are tightly packed so they have no intercellular spaces in them.
