    1. 1. By: DORA INDRANA,S.Pd.M.Pd
    2. 2. Plant tissue Animal tissue
    3. 3. PLANT TISSUE GENErALLy PLANT TISSUES ArE dIvIdEd INTo : 1. Maristematic tissue 2. Permanent tissue
    4. 4. 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 
    5. 5. • 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
    6. 6. Base on placed in plant, there are two types of meristems: • APIcAL MErISTEMS • LATErAL MErISTEMS
    7. 7. Root Apical Meristem 1. Root cap initials 2. Protoderm 3. Ground meristem 4. Procambiu m 5. Root cap
    8. 8. Types of meristems base on basic formed : 1. 2. Primary growth Secondary growth
    9. 9. There are two theory that explain about primary growth   Histogen's theory Tunica Corpus's theory
    10. 10. S e c o n d a r y g r o w t h Secondary growth
    11. 11. PERMANENT TISSUES• Meristems which cannot divide further and have attained a definite form and size
    12. 12. PERMANENT TISSUES1. Epidermal tissue 2. Vascular tissue 3. Ground tissue
    13. 13. EpidErmal TissuE
    14. 14. 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 •
    15. 15. Vascular TissuE Pays the the role in carrying substances to cover the needs of plants • Divided into two: 1. Xylem 2. Phloem •
    16. 16. Vascular tissue
    17. 17. 1. XYLEM  Helps in transport of water and soluble mineral nutrients from roots to all the parts of the plant body.
    18. 18. 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.
    19. 19. Xylem
    20. 20. FLOEM To transport sugars and other food materials from the leaves to the rest of the parts of the plant body.
    21. 21. Phloem
    22. 22. Floem consist of : Fibers,  Parenchyma and  Ray cells
    23. 23. TYPE OF VASCULAR TISSUE 1. Consentris 2. Colateral 3. Bikolateral 4. Radial
    24. 24. Consentris CONSENTRIS
    25. 25. Colateral COLATERAL

Characteristics of and difference between xylem and phloem Characteristics  Definition  Xylem  Phloem Dead, complex permanent Living, complex permanent tissue tissue Xylem tracheids and tracheae Sieve tubes and companion cells  Associated elements Xylem fibres and xylem parenchyma Phloem fibres and phloem parenchyma  Non-living components Xylem tracheids Only Phloem fibres Only xylem parenchyma Sieve tubes companion cells and phloem parenchyma Conduction of water Conduction of food and other organic substances  Essential elements  Living components  Function (Source: http://www.tutorvista.com/content/biology/biology-iii/plant-histology/pholem.php)
    27. 27. Ground Tissue
    28. 28. 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.
    29. 29. 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
    30. 30. Collenchyma
    31. 31. PARENCHYM  The cell membranes composing the tissue are thin  Composed of living cells  Has a big vacuole  Polygonal  Has a space between cell
    32. 32. These cells synthesize and store organic products in the plant. Most of the plant's metabolism takes place in these cells.
    33. 33. Parenchyma
    34. 34. 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.
