A tissue is a group of cells which are
similar in origin, but dissimilar in form and function.
dissimilar in origin, form and function.
dissimilar in origin, but similar in form and function.
similar in origin, form and function.
Correct Answer :
D. similar in origin, form and function.
A group of structurally similar or dissimilar cells that perform a common function and have a common origin is called a tissue. A plant is made up of different kinds of tissues. The complex tissues are, however, composed of different kinds of cells and they perform different types of functions.
