*BUTTRESS ROOT
-Thick support roots that grows from the stem above the ground
-These roots hold the tree firmly to the ground, giving it extra support
-example: angsana tree, casuarina tree, durian tree
*PROP ROOTS
- Roots which grows from the stem or brances into the ground to support the plant
- Example: banyan tree, pandan plant, maize plant
*PRICKLES
- Sharp outgrowth of the epidermis and can be easily removed from the stem
- Exampel: rose plant
*TENDRILS
- Curly string like structures modified from stems and leaves
- Curl and twine round parts of other plants or object to help the plant to climb
- Example: cucumber plant, bitter ground
plant, pumpkin plant
*THORNS
- Sharp modified branches that cannot be easily removed.
- Act as hooks to hold on the supports
- Example: bougainvillea shrub
*CLASPING ROOTS
- Roots that grip onto other plants or structures to get support
- Example: money plant, betel vine plant
*STILT ROOTS
- Roots that develop from the main stem and grow onto ground for support
- Example: mangrove tree
