Question

Why is seed dispersal important?
A.Survival of plants.
B.Introduction of plants.
C.Adaptation of plants.
D.None of these.

Answer 1

Hint: Seed dispersal is the movement, transport or spread of the seeds from the parent plant to any other place or surface. As plants have limited mobility, they are dependent on the dispersal vectors to transport their seeds from one place to the other for a variety of reasons.

Complete answer:
 There are various abiotic and biotic vectors involved in the dispersal of the seeds from one place to the other. These vectors are wind, water, and living animals. They help to transport the seeds from the plant from one part to another for demographic and genetic structure of the plant population. There are some plants known as serotinous and disperse their seeds in response to the environmental stimulus.
There are different benefits of dispersal of the seeds such as survival rate is higher away from the parent plant. It also helps to save the new seeds from the competition of other seeds and place them in one place. Seed dispersal also helps the plant to reach favorable habitat for survival through their movement, it also results in reaching of the plants to new habitats. Thus, overall seed dispersal helps in the survival of plants in new environments and saves the species by providing them different habitats for survival.

Hence the correct answer is OPTION(A)

Note: Seed dispersal also has many consequences for both ecology and evolution of the plants. It is important for the species migration and plays a vital role in the origin and maintenance of species diversity thus helping to maintain ecological balance.
