Epidermis aids in protection against loss of water, mechanical injury and invasion by parasitic fungi. Collenchyma is one of the three fundamental tissues in plants. What are the roles of epidermis in plants? Q13. Page - 5 . Epidermal cells of roots have hairs that greatly increase the absorptive surface areas for the absorption of water and nutrients. All three types of plant cells are found in most plant tissues. Class- IX-CBSE-Science Tissues. The epidermis may be thicker in some plants living in dry habitats or often secrete a waxy, water- resistant layer on their outer surface called cutin (chemical substance with waterproof quality) to prevent water loss. Back of Chapter Questions . CBSE; ... Q13: What is the role of epidermis in plants? The epidermis is the outer layer of your skin, and it plays an important role in protecting your body from things like infection, UV radiation, and losing important nutrients and water. The epidermis is formed of single contimous layered cells. Question 14. Components of plant epidermal tissue Epidermis Thus, cork cells prevent water loss from plants and also make them more resistant to bacterial and fungal infection. Class 10 Class 12. This is an answered question from Chapter 6. View Answer Q14:How does the cork act as a protective tissue? Though useful to plants as they increase in size and girth, lignin does have its drawbacks. It protects all the external parts of the plant against loss of water, mechanical injury and invasion by parasites etc. Epidermal cells on the aerial parts of the plant often secrete a waxy, water-resistant layer on their outer surface. Root hair present on epidermis of root help in absorption of water and mineral from soil. Like the skin epidermis, the epidermis of the plant covers the outer surface and thus covers all plant tissue from the roots to the tip. Question 2: Name the three types of transpiration. What is the role of epidermis in plants? Dermal Tissue. Tags: ... Dermal, Vascular and epidermis . What is the role of epidermis ? The prevention of water loss. aerenchyma( in case of aquatic plants) and chlorenchyma (in terrestrial plant) . Three major types of plant tissues are dermal, ground, and vascular tissues. Complex tissues are made of more than one type of cells. HARD. The epidermis in desert plants is covered by a waxy coating. NCERT Solutions. Short Questions. Epidermis is the outermost layer of cells of the primary plant body, covering all external surfaces of herbaceous plants and forming an interface between the plant and its environment. Upvote(0) How satisfied are you with the answer? (e) Connective tissue whose matrix is fluid, ... For example parenchyma, epidermis etc. It is usually single layered .
