example the following with examples
a) tendril climbers
b) twiners
c) thorns

Dear Student,

Ans a)

Tendril are thread-like structures that develop from the stem and are spirally coiled to help the plant to climb (E.g. grapevines)

Climbers are plants that take support from neighbouring structures such as trees, walls etc. to climb up. The examples of climbers are money plant, jasmine etc.

 Ans b)

Twinners are such plants that are able to curl around a strong support (Example: rods, stems of other plants,etc) which helps them to grow upwards. These plants may use their leaves or their stems for curling/twining around the support. 
Examples: Morning glory, Pole beans 

P.S. kindly post separate questions in separate threads.
