Question

Describe the various ways by which seeds are dispersed.​

Answer 1

Answer:

 Dispersal by wind:-Winged seeds of drumstick and maple, light seeds of grasses or hairy

seeds of aak (Maddar),get blown off with the wind to far away places as they are light.

 Dispersal by water:-Seeds develop floating ability in the form of spongy or fibrous outer

coat as in coconut thus get dispersed by water.

 Dispersal by animals:-Seeds dispersed by animals are spiny with hooks which get

attached to animal body and get carried to distant places.

Answer 2

Answer:

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.

Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.
