Climber plants have weak stem so in order to reach Sun light they climb up some support with some special organ.
Creepers , on the other hand literally ' creep ' along the soil surface and spread over a long distance.
1 )A climbing habit has evolved independently in several plant families, using many different climbing methods.
Some plants climb by twining their stems around a support (e.g., morning glories, Ipomoea species).
Others climb by way of adventitious, clinging roots (e.g., ivy, Hedera species), with twining petioles (e.g., Clematis species), or using tendrils, which can be specialized shoots (Vitaceae), leaves (Bignoniaceae), or even inflorescences (Passiflora).
Species of Parthenocissus (Vitaceae) produce twining tendrils that are modified stems, but which also produce adhesive pads at the end that attach themselves quite strongly to the support.
The evolution of a climbing habit has been implicated as a key innovation associated with the evolutionary success and diversification of a number of taxonomic groups of plants.
2 ) Creeper = It is a prostrate or trailing plant that spreads by means of stems that creep.
