Tissue
Characteristics
Functions
Parenchyma
- consist of thin-walled cells
- have large vacuoles
- least specialized
- can be found in all the organs  plant
- store products of photosynthesis
   (sugar/starch)
- *palisade mesophyll cells
   *spongy mesophyll cells
     ~specialised(photosynthesis)

Collenchyma
- consist of elongated, polygonal
   cells
- cell walls are thickened by
  *cellulose
   *pectin
- strong and flexible
- source of support in herbaceous
   plants
Sclerenchyma
- more rigid
- thickened by lignin
- most of cells are dead at
   maturity
- supports and strengthen plant
   body
- provides protection for the plant
