Question

1. Meristematic tissues

2. Permanent tissues

Answer 1

Meristematic tissues are cells or group of cells that have the ability to divide. These tissues in a plant consist of small, densely packed cells that can keep dividing to form new cells. Meristems give rise to permanent tissues and have the following characteristics:

the cells are small,

the cells walls are thin,

cells have large nuclei,

vacuoles are absent or very small, and

there are no intercellular spaces.

Meristematic tissues is found in the following locations:

near tips of roots and stems. This is called apical meristems.

in the buds and nodes of stems.

in the cambium between the xylem and phloem in dicotyledonous trees and shrubs.

under the epidermis of dicotyledonous trees and shrubs (cork cambium).

in the pericycle of roots, producing branch roots.

______________________________________...

The cells of permanent tissues do not have the ability to divide. These cells are already differentiated in different tissue types and is now specialized to perform specific functions. They are subdivided into two groups, viz, simple tissues consisting of cells which are more or less similar, e.g. epidermis, parenchyma, chlorenchyma, collenchyma, sclerenchyma and complex tissues consisting of different kinds of cells, e.g. xylem and phloem.

Simple tissues are:

Epidermis

Parenchyma

Chlorenchyma

Collenchyma

Sclerenchyma

Complex tissues are:

Xylem

Phloem
