Welcome back students, we were seeing the topic on plant tissues. Let's continue. We were seeing the mesmeratic tissue in which the mesmeratic tissue also becomes a permanent tissue. The first type of permanent tissue is the simple permanent tissue. And these are the tissues which are also called as simple because they are composed of similar type of cells and they have the common origin and permanent function. So they are called as simple tissues. Now they are further classified into four types of tissues. First is the parent chima, second is colon chima, third is chlaren chima and fourth one is the epidermis. So simple permanent tissue are mainly simple due to the similar type of cells as well as they have common origin and function. Let's start with the parent chima tissue. Parent chima tissue in which the moment is the most specialized primitive tissue. But it can say old. It mainly consists of thin world cells. So cells are mainly thin world and the main function of parent chima tissue is the assimilation. Assimilation is also called as absorption and storage of reserve food material like starch, fats and proteins. So parent chima tissue mainly involves the process of absorption and storage of starch, fats and proteins. They also store the waste products like gums, raisins and the inorganic waste material. So these are the parent chima tissue cells where the mainly have the function of absorption and storage and their cell wall is they have a thin world cells. The location of parent chima tissue cells is that these tissues formed in the palliacid or the spondy tissue in the green leaves and stem cortex in the herbs where the photos and the leaves are cut. So parent chima is a form of parent chima is a form of parent chima possessing large air cavities. Okay. When aquatic plants, the cavities in the industrial spaces gives buoyancy to the plant and helps them float in water. So the large cavities in the present in the parent chima tissue cells in the aquatic plant is responsible for the buoyancy. Next comes the colon chima. Colon chima cells in which colon means the gum and in chima means the infusion. So the infusion of gum that means it is chiefly in the hypothalamus of the stems and leaves where and it is abstained to the monocorting the root. So as you can see here, so the infusion of the gum in the cells, so the dendritus, so due to this they are called as colon chima. So students in this session we have seen the simple permanent tissues meaning divided into parent chima, colon chima, sclerin chima and epidermis. Parent chima are the cells which have thin world and they are responsible for the assimilation and storage. They are located in this palliacid or you can say the spondy tissue, spondy tissues in the green leaves and stem cortex. Next comes the colon chima which is mainly responsible for the infusion of gum in the cells and it is present in the hypothalamus of the stems and leaves. The location of colon chima tissue acts as a supporting tissue in the stems of the young plants. It provides mechanical support elasticity and tensile, that means strong strength to the plant body. So the plants in the manufacturing of sugar and storing it as, storing it as a starch. Next it is present in the margin of the leaves and resists the tearing effect of the vent as it gives the tensile strength to the body that means it can resist a very tearing effect of the vent also. The students in this session we have seen the plant tissues and for the session we will have a more detailed look regarding the plant tissues. Thank you.
