Answer 1

epidermis means outer covering
it protects roots from external injury .

Hey dude here is the one ........❗❗✌✌⤵⤵

#At first....let us try to know what we have to study....in the plant...⤵⤵✌☺

❗❗ ...........PLANT TISSUE.......❗❗

MERISTEMATIC. PERMANENT.
⤵⤵
1), Apical. 1), Simple Perm. 2), Complex permanent 3), Special prm.
2), Intercalary
3,) Lateral

Here , #( from simple permanent tissue), ⤵⤵

1) ,Simple permanent tissue =

#) Supporting tissue = Parenchyma, Collenchyma, Sclerenchyma.....❗❗☺
#) Protective tissue = Epidermis, Cork....❗☺❗☺

Now, PROTECTIVE TISSUE..... ⤵⤵

#, Epidermis ..➖➖1),It is the outermost protective layer of plant organs.....❗❗
2), It is commonly single layered . Cells of epidermis tissue are elongation and closely packed.......❗❗
3), The cells are generally thickened on their outer and thin - walled on inner side........❗❗
4), In aerial parts of plants, the epidermal tissue is comprised of cuticle [ IT IS NON- CELLULAR COATING OF WAXY SUBSTANCE LIKE - CUTIN AND WAX].......❗❗

5), In many plants, the epidermal tissue bear cutinised hair over , called Trichiomes....It helps in developing an insulating stationary layer of air over surface in order to reduce rate of transpiration.......❗❗
