3. PLANT TISSUE
GENErALLy PLANT TISSUES ArE
dIvIdEd INTo :
1. Maristematic tissue
2. Permanent tissue

5. Meristematic tissue
Increase in plant length by produce new
cells continuously.
 Located at the growing shoot and root
apex
 The cells are relatively smaller in size
compared to mature cells
 Has large nucleusand the cytoplasm is in
abundance


6. • Every cell has a nucleus, which is
situated in the center of the cell
• The cells have a thin cell wall, which is
composed of only cellulose

7. Base on placed in plant, there are two
types of meristems:
• APIcAL MErISTEMS
• LATErAL MErISTEMS

14. PERMANENT TISSUES• Meristems which cannot divide
further and have attained a
definite form and size

15. PERMANENT TISSUES1. Epidermal tissue
2. Vascular tissue
3. Ground tissue

16. EpidErmal TissuE

17. Epidermal Tissue
Consisting of the cells in polygonal
or flat shapes
• The functions of epidermal
tissue: those are as a protector for
the tissue beneath; as a protector of
the plant from the presence of
excessive evaporation; also has an
important role in gases exchange,
metabolic substance ecretion and
water absorbtion
•

18. Vascular TissuE
Pays the the role in carrying substances to
cover the needs of plants
• Divided into two:
1. Xylem
2. Phloem
•

19. Vascular tissue

20. 1. XYLEM

Helps in transport of water and soluble
mineral nutrients from roots to all the parts
of the plant body.

21. Xylem consist of :




Parenchyma cells,
Fibers,
vessels,
Tracheids
Xylem cell types. (A) Sclereid
reinforced witrh lignin;
(B) tracheid of Woodwardia,; (C)
Pinus, a conifer (one-third of cell
show); (D) fiber tracheid; (E-G)
angiosperm xylem
-- (E-F) tracheids, (G) vessel
member.

22. Xylem

23. FLOEM
To transport sugars and other food materials from
the leaves to the rest of the parts of the plant body.

24. Phloem

25. Floem consist of :
Fibers,
 Parenchyma and
 Ray cells

30. Ground Tissue

31. Ground Tissue
The ground tissue system synthesizes organic
compounds, supports the plant and provides
storage for the plant. It is mostly made up
of parenchyma cells but can also include
some collenchyma and sclerenchyma cells as
well.

33. COLLENCHYM
- Homogenous tissue
- Has no lignin
- The primary cell wall is thickened by pectin
compound, cellulose and hemicellulose
- Located in stems and leaf, located right
under epidermis, rarely in root
- Function : as a plant lasing, particularly in
growing active organs of plants

35. Collenchyma

36. PARENCHYM
 The cell membranes composing the tissue are
thin
 Composed of living cells
 Has a big vacuole
 Polygonal
 Has a space between cell

37. These cells synthesize
and store organic
products in the plant.
Most of the plant's
metabolism takes place
in these cells.

38. Parenchyma

39. SCLERENCHYM
The cell walls are evenly thickened and lignified
and usually pointed at both ends. The nucleus
is absent and hence the tissues are made up of
dead cells.
They have simple pits in the walls and the wall
between adjacent cells is prominent. It is found
abundantly in cells like coconut, jute and hemp.
 They provide elasticity, flexibility and rigidity to
the plant body forming a mechanical support.

40. Sclerenchyma
SCLERIDS
