Question

I have a doubt that tissue has a definition that a group of cell having similar in structure origin and function so why Complex tissue is made up of two type of tissue how does it possible please answer me in easy language

Answer 1

Answer:

Let me first write down the exact definition of a Tissue. It says that:

"A tissue of a group of structurally similar or dissimilar cells having a common origin, which perform a similar function or a set of similar functions"

Explanation:

Now the definition clearly suggests that the types of cells in a single tissue can be same or not. That's why there are two categories of tissues. One is the simple one which consists of all similar types of cells and the other one is the Complex one which consists of more than one types of cells. So I feel like you might have read an incomplete definition somewhere. The definition that I've mentioned above covers both simple and complex tissues. Hope you like the answer!
