Question

Identify the type of creeper
A. Stolon
B. Offset
C. Thorn
D. None of these

Answer 1

Hint: Creepers are weak-stemmed plants which spread horizontally along the soil. They grow along the ground or up a wall by extending their branches or stems.

Complete answer:
Option A: Stolon is the stem which grows horizontally along the ground. They are also known as runners. Therefore this is a correct option.

Plants with stolons are called stoloniferous. Stolons is a plant propagation strategy. They produce new plans at the nodes which is a mean of asexual reproduction.The newly produced plants will be clones of the mother plant. Some plans use stolons for the spread of their tubers in order to survive the dry periods in aquatic habitat.

 Eg: strawberry, potato, hydrilla ec.

Option B: Offsets are plants which produce plantlets from a part still attached to the parental plant, usually from the very next nod. Offset are stem modification which are shorter and thicker and usually found in aquatic plants. Eg: pistia.Therefore, this is the incorrect option.
Option C: Thorn are small, sharp stem modification. They point outwards from the stem and protect plants from herbivorous animals. Eg: Bougainvillea.Therefore, this is the incorrect option.
Option D: option A is correct, Therefore, this is the incorrect option.

Hence, the correct answer is option (A)

Note: Stolons arise from the base of the plant. And the nodes of the stolon produce roots. After this, the hormones produced by roots will stimulate growth of the stem and shoot at the nod. Stolon dies away after the formation of new plants. The tubers of potato are modified stolons that can store food.
