Question

Which of the following seeds is scattered through water?
A. Ragma
B. Coconut
C. Mango
D. None of the above

Answer 1

The seeds produced by plants are scattered through various agents. They can be either biotic or abiotic. Biotic factors are animals, or birds and abiotic agents are water and air.

Complete answer:
Seeds that are dispersed through water can be transported to a large distance. These seeds should have special characteristics for this mode of scattering. They should possess a spongy or fibrous layer on the outer portion. This layer is helpful in cases where it should be dispersed on the water surface for long periods. The seeds like coconut are scattered by means of water. Once it reaches the shore, it starts to germinate.
-Ragma is also known as kidney beans. They are seeds involved in the class of pulses. These are dispersed through the wind. . Thus it is not an appropriate answer.
-The seeds of mango are scattered utilizing Biotic agents such as animals, birds, and also humans. These organisms consume the fruit and disperse the seeds. Thus it is not an appropriate answer
-It is not the right option, since there is an answer among the given options.
Thus, the most appropriate option is B-Coconut which is dispersed through water.

Note: There are broadly two kinds of seed dispersal. Autochory and Allochory. In Autochory, the dispersal mechanisms are by the plant’s mechanisms. That is there is no involvement of an externally occurring vector or transporter. In allochory, the plant takes the help of various external vectors such as water, wind, and animals. The dispersion through allochory attains larger distances.
