Answer:
this is your answer
Explanation:
ans 7 Collenchyma, in plants, support tissue of living elongated cells with irregular cell walls. Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross section. The strength of the tissue results from these thickened cell walls and the longitudinal interlocking of the cells.
ans 9Epiblema is an outermost single layer of the root. They are the imperfect epidermis that replaces a true epidermis in submerged plants to protect the growing roots from the extremities of the environment.
