1. SIMPLE PERMANENT PLANT TISSUES
CLASSIFICATION

3. PARENCHYMA CELLS HAVE THIN CELL WALLS LIVING CELLS
LOOSELY PACKED CELLS
LARGE INTERCELLULAR SPACES (SPACES BETWEEN CELLS)

4. FUNCTIONS OF PARENCHYMA TISSUE
PROVIDES SUPPORT
STORES FOOD FOR THE PLANT
PHOTOSYNTHESIS
HELPS THE AQUATIC PLANTS TO FLOAT BY MAKING THEM BOUYANT

6. CHLORENCHYMA

8. AERENCHYMA

11. COLLENCHYMA

12. FUNCTIONS OF COLLENCHYMA
IT ALLOWS EASY BENDING IN VARIOUS PARTS OF PLANTS WITHOUT BREAKING THEM
MECHANICAL SUPPORT TO PLANTS
PRESENT IN LEAF STALKS BELOW EPIDERMIS

15. COLLENCHYMA CELLS CELLS ARE THICKENED IRREGULARLY AT CORNERS
VERY LITTLE INTER CELLULAR SPACE

16. SCLERENCHYMA

17. SCLERENCHYMA TISSUE MAKES THE PLANT HARD AND STIFF CELLS ARE DEAD
CELL WALLS CONTAIN LIGNIN ( CEMENT LIKE SUBSTANCE WHICH HARDENS THE CELL)
NO INTERNAL SPACE INSIDE THE CELL
GIVES MECHANICAL SUPPORT

19. LOCATION OF SCLERENCHYMA
GRITTY FRUIT eg: GUAVA (AMROOD)
STEMS AROUND VASCULAR BUNDLES
LEAF VEINS
HARD COVERING OF SEEDS AND NUTS

20. EPIDERMIS UPPER MOST LAYER OF CELLS A SINGLE LAYER OF CELLS IS PRESENT
IT IS PROTECTIVE FOR THE PLANT.
NO INTERCELLULAR SPACES, NO SPACE BETWEEN CELLS BECAUSE THEY ARE PROTECTIVE IN FUNCTION.

21. RHOEO PLANT

24. COMPLEX
PERMANENT
TISSUE

30. PHLOEM
