8. (1) how many days do the cell in the plant tissue will live?

(2) what is a tissue?

(4)how many varies of tissues are present in plant?

9.Bark cells are mostly impervious to water and gases due to deposition of a material calledsuberin. However, there are pores at some locations in the bark called lenticels that allowexchange of gases.

         There is no specific experiment to prove this. However, by studying the anatomy of plants, it has been proved that they are impervious to water and gases.

10.The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss. Some of the many types of cells in the epidermis are shown below. Most epidermal cells lack chloroplasts.

12.Plant looks very simple from out but entire system needs a good coordination from process of photosynthesis to storage and utilizing in leaves the inner tissues sponge parenchyma and palisade parenchyma ams at the center xylem and phloem tissue these two carry water and other carry food material to all the body parts and absorption of water involves osmosis process as root hair contains a membrane called as cell sap which is more concentrated next is absorbing sunlight by chlorophyll the green pigment in the chloroplast all these functions need to be coordinated and it is a complex process but happens in seconds.
