Question

An example of fruit which is dispersed by bird is
A. Calotropis
B. Mirabilis
C. Argemone
D. Bignonia

Answer 1

Hint:-: Dispersion by birds is the process in which a bird carries seeds in its beak which is soft, fleshy and with vibrant colour commonly either red or orange and is called “syn zoochory”. Birds cannot carry complete fruit either they leave behind, or it just fall out but some of is part is left in their beak which contains small seeds and thus get a new spot for their germination.

Complete step-by-step solution:-Birds carry seeds which are fleshy and sticky either in its beak or they just stick upon their body and that is the way dispersion takes place. For reproduction in simpler language we can say that for increasing the number of their species, evolution and for continuation the survival of their species seeds dispersal is needed. Plants disperse their seeds in a variety of ways like wind dispersion, water dispersion, gravity are also important means and by animals. It is the transport or movement of seeds away from its parent plant is known as seeds dispersal. This is necessary for their regrowth to give height to the graph of its number of species. Bignonia’s flower is of bright colour that attracts the birds for their seed’s dispersal in a wider range. Seeds with the help of birds disperse and a new plant of Bignonia grows. This plant generally attracts hummingbirds towards it for seed dispersal. Hence the correct option is (D) Bignonia.

Note:-
 Bignonia is a flowering plant which is usually found in the southern USA and central region of South America. It is of vibrant colour in the shade of green and is called by the name cross vine. Its colour, blooming time and height can differ according to the climate in which it is grown, so it is necessary to look upon the environmental conditions.
