This PowerPoint presentation discusses the three main types of plant tissues: parenchyma, collenchyma, and sclerenchyma. Parenchyma tissue is composed of simple cells found in soft plant parts where photosynthesis and food storage occur. Collenchyma tissue has thick cell walls only at the corners, providing flexibility and support. Sclerenchyma tissue has uniformly thick cell walls all over, giving strength and support to plant structures.

3. PLANT TISSUES

4. INTRODUCTION
TISSUES ARE GROUPS OF SIMILAR
CELLS THAT HAVE A COMMON
ORIGIN AND PERFORM SPECIFIC
FUNCTIONS.

5. TYPES OF PLANT
TISSUES
PARENCHYMA
COLLENCHYMA
SCLERENCHYMA

6. PARENCHYMA
COMPOSD OF CELLS WITH THE
SIMPLEST STRUCTURE.
SEEN IN THE SOFT PARTS OF THE
PLANT.
HELPS IN PHOTOSYNTHESIS AND
THE STORAGE OF FOOD.

7. PARENCHYMA

8. COLLENCHYMA
COMPOSED OF CELLS THAT ARE
THICK ONLY AT THE CORNERS OF
THE WALL.
PROVIDES FLEXIBILITY AND
SUPPORT.

9. COLLENCHYMA

10. SCLERENCHYMA
COMPOSED OF CELLS THAT ARE
UNIFORMLY THICK ALL OVER THE
CELL WALL.
PROVIDES STRENGTH AND
SUPPORT TO PLANT PARTS.
