2. Plant Tissue

3. Tissue
•Definition;
A collection of cells performing a specific function is
called tissue.
Types;
There are two types of plant tissue.
1) Meristematic Tissue
2) Permanent Tissue

4. Meristematic Tissue
•Meristematic tissue are cells or group of cells that have
the ability to devide.
•Occurrence; Growing region of plant (root, shoot, etc)
•Shape; spherical, Oval , rectangular.
•intercellular space are absent.
•Vacuoles are absent in this
tissue.
•Cytoplasm are dense.

5. Types of Meristematic Tissue
•1) Apical Meristem:
•Present at the growing region of the apex of the plant
organ.
•present at shoot and root apex.
•increase length of root and stem.
•2)Lateral Meristem:
•found along the sides of root and stems.
•increase diameter of root and stems.

6. Intercallary meristems:
•present at the base of leaves or internodes
•increase length of leaves and stem.

7. Parmanent tissue
•Tissue that have become muture and do not have the
ability to divide further are called parmanet tissue.
•They do not divid and have permanent shape and size.
Types:
•1) Simple tissue
•2)Complex tissue

8. Simple Permanent tissue
•These tissue are made of one type of cell.
•cell are structurally and functionally similar.
•Types:
•1)parenchyma.
•2)collenchyma.
•3)Sclerenchyma

9. Complex permanent tissue
•These tissue are made up of more then one type of
cells.
•There are two types of complex tissue.
•1) Xylem
•2) phloem
