Q. 55 C5.0( 2 Votes )

Name any two simple and two complex permanent tissues in plants.

Answer :

Simple permanent tissue- these are group of cells that originate similarly, have similar structure and function. Eg- Parenchyma, Epidermis, Collenchyma and Sclerenchyma.


Parenchyma provides support to plants and stores food. Epidermis protects from pathogens, regulates water loss from plant’s body etc. Collenchyma gives strength to the plant and sclerenchyma makes the cell wall strong and impermeable to water.


Complex permanent tissue- These tissues contain more than one type of cells that form a unit and work collectively. Eg- Xylem and Phloem ; Xylem is composed of 4 cells(tracheids, vessel elements, xylem fibers and xylem parenchyma) that work together in carrying water and minerals up and down in the plant. Phloem is too composed of 4 cells (sieve tubes, phloem parenchyma, companion cells and phloem fibers.) that work together in transporting food from leafs to other parts of plant.
