Question

Seeds travel with water is filled with
A. Water
B. Air
C. Protein
D. None of the above

Answer 1

Hint: Seed is the embryonic part of the plant that is enclosed by an outer covering or may be fruit. The formation of seeds in plants results due to the process of sexual reproduction in plants. The seed can give rise to the new plant.

Complete Answer:
Dispersal of seed: Seed dispersal is a way by which seeds get away from the parent plant to a new place in order to start their lives or for germination. The word ‘Dispersal’ means spread or scatter. As the plants cannot move because they have put down roots, so the method of seed dispersal is an advantage for the plants.

Modes of seed dispersal:
 There are many ways of seed dispersal.
1. Wind dispersal: In this method seeds get dispersed by the action of wind. The seeds that get dispersed through this mode must be small and light in weight. Example – dandelion seeds, Orchid seeds, etc.
2. Explosive action: In this type of seed dispersal method fruits can fling or throw their seeds away from them to a new place when the fruit is ripened. This is a rapid type of plant movement. Example – Pea pods, Gorses and violets, etc.
3. Animal dispersal: In this mode of seed dispersal animals help in seed dispersal. For example – mice, ants, squirrel monkeys, etc collect nuts or fruits in the spring season and store them in the ground by burying them for the winter season. But when the winter season comes they leave a few seeds buried which can germinate into a new plant.
4. Water dispersal: In this mode of seed dispersal seeds are dispersed by water currents. For this the seed that floats on water must be buoyant. The seeds that float on water have an air cavity inside which is filled with air and provide buoyancy to the seed. Example – water lily, coconuts, etc.

So, it is clear from the above discussion that the seeds travel with water and are filled with air.

Hence, option B is the correct answer for this question.

Note: Dispersal of seeds is very important for the survival; of any plant species. Seeds dispersal allow the spread of that particular plant to a wide range area. This also avoids competing with other plants for food and other resources.
