Answer 1

Answer:

It wouldn't be interesting to watch a creeper entwine its tendril to the support as they don't have tendrils. Creepers have prostrate stems which root at intervals. Their stem is long, flexible and sensitive. Creepers are of three kinds :

a) Runners - They are special narrow, green and above ground horizontal or prostrate branches which develop at the bases of erect shoots. A number of runners arise from erect shoots and spread in different directions. For example, Oxalis, Lawn grass etc

b) Stolon - They are elongated, horizontal or arched runners which can cross over small obstacles e.g. Jasmine, Wild strawberry, Peppermint . The tip of stolon grows above the ground level.

c) Offsets - They are one internode long small runners which are found in rosette plants at the ground or water level e.g. Water lettuce, water hyacinth.
