Answer 1

A plant is made up of different kinds of tissues . Tissues are classified into two main groups namely, meristematic and permanent tissues based on whether they are capable of division or not.
Meristematic tissues are capable of division, the meristems which occur at the tips of the roots and shoots and produce primary tissues are called apical meristems. Root apical meristem occupies the tip of root and shoot apical meristem occupies tip of shoot, and intercalary meristem occurs between mature tissues.
The cells of permanent tissues do not divide further.
permanent tissues are of two types 1.simple permanent tissue and 2.complex permanent tissues.
simple tissue are made of one kind of cells and they are categorised into 1.parenchyma 2.collenchyma 3.sclerenchyma.
complex tissues are made up of more than one kind of cells. they are categorised as 1.xylem 2.phloem.
