Here the question is asking about the epithelial tissue and we have to find the two statements for the epithelial tissues.
00:10
And here we have six different statements.
00:14
So such epithelial tissues, they can be classified based on the number of cells, the shape of cells and the type of cells and the type of cells and even from the number of layers of cells so if there is only single layer of cell then it can be known as the simple epithelial cells and if there is presence of many cell layers then it can be called as stratified epithelial tissues and according to the shapes it can be the squamished epithelial tissue cuboidal and columnar and epithelial tissues are widespread throughout the body and it can form the covering of all body surfaces function in the protection secretions absorption excretion filtration diffusion etc etc now let us look at the options given so the very first option a is epithelial tissue are characterized by shapes of cells and how many layers of cells are present in the tissue.
01:43
So this option is correct because epithelite tissues, they can be classified or categorized by shapes as well as how many layers of cells present.
01:56
Here we have already seen that categories and different shapes.
02:04
The b option given here is epithelial tissues have polarity.
02:08
So epithelial tissues have polarity, the statement is correct.
02:13
Epithelal cell polarity is characterized by the cells with apical and basolateral membrane domains, which are separated by adherence and tight junctions.
02:31
So the statement is true because epithelial tissues do have polarity.
02:36
The c option given here, that's saying the epithelial tissues are.
02:40
Are vascular and contain blood vessels.
02:47
So this statement is not true because avascular, they do not have vessels or they do not have the blood vessels crossing the tissues...
