plant tissue by simranjot singh

1. PLANT TISSUE
Tissues in plants that divide throughout their
life.
Plant tissues can be classified as:
Growing or Meristematic tissue
Permanent tissue

3. MERISTEMATIC TISSUE
The growth of plants occurs in certain
specific regions.
This is because the dividing tissue is known
as meristematic tissue.
Composed of actively dividing ceIIs,
responsible for the production of cells.
Capacity for division is restricted to certain
parts of the plant body called meristems.
Which are active throughout the life of the
plant body.

4. KINDS OF MERISTEMATIC TISSUE
• Apical meristems – found at the tip of stems &
roots.
• Lateral meristems – a.k.a. cambia
• Intercallary meristems – found at the bases of
young leaves & internodes.

5. PERMANENT TISSUE
Tissues that attained their mature form and
perform pacific functions.
They stop dividing
Types:
• Simple permanent tissues
• Complex permanent tissues

1.Formed of only
one type of cell
1.Formed of more
than one type of
cell
2.All cells perform
the same function
2.Different cells
carry out
different function
