Tree Diagram Three

      Draw Tree Diagram with the help of following points. A Tissue may be defined as a group of cells having some shape, size, origin, function and the same type of development. Tissues are basically classified into two groups namely, meristematic tissues, and  permanent tissues. Meristematic tissues are divided into two, these are position based and origin based. Permanent tissues are further divided into two groups. They are simple tissues and complex tissues. On their basis of their position in the plant body meristematic tissues are classified as aplicle – intercalary, and lateral. On the basis of origin, meristematic tissues are divided into 3 groups; they are Pro – meristem, Primary – meristem and secondary – meristem. Simple tissues are classified into 3 groups, namely parenchyma, collechyma, sclerenchyma, The two complex tissues are found in vascular plant. They are xylem and phloem.
