Question

In drumsticks, seeds are dispersed by
(a)Water
(b)Animal
(c)Wind
(d)Explosive mechanism

Answer 1

Hint: The seeds of the drumstick are dispersed by wind (anemochory). The wind is the natural and primary means by which seeds are dispersed. Such type of dispersal is mainly observed in those plants which produce very light seeds. Example: drumsticks, orchid plant, dandelions, ash, puya, willowherb.

Complete answer:
There are several other ways in which seeds are dispersed. These are as follows:
By Water: In such a mode of seed dispersal, seeds float away from their origin plant. These are chiefly found in those plants which live within the water or nearby the water bodies like beaches, lakes, ponds, etc. Example: coconut, palm, mangroves, water lily, water mint.
By Animals: There are different ways in which animals and birds disperse the seeds. Few animals and birds eat the entire fruit and only the juicy part is digested by their system and the seeds are excreted out with their droppings. There are a few plants that have seeds with hooks that catch on the fur of animals and are carried away to different places. Example: Blackberry, cherry, tomato, Burdock.
By Gravity: As the fruits fall on the ground from the tree due to the force of gravity, they seldom roll down to some smaller distance, get buried in the soil, and germinate into a new plant. Example: Apples, canna, coconuts, passion fruit
Explosions: Explosions in fruits actually suggest the bursting of fruits with all its energy. In such mode, as the fruits get ripened, it shoots out its seeds into the external environment like in okra, Lupins, gorse, and broom
So, the correct answer is “ wind”

Note: The seeds of drumsticks disperse from the pods when the ripe dry fruits burst and scatter the seeds and germinate in places with favorable conditions. The shape and size of the drumstick seed aid it in Aerial mode of dispersal.
