Question

Widely distributed plants are dispersed by which of the following?
(a) Spores
(b) Vegetative means
(c) Seeds
(d) Fruits

Answer 1

Hint: The product formed after fertilization in the flowering plants which is an embryonic plant covered in an outer layer.

Complete answer:
Seeds are formed from ripened ovules, which are formed after fertilization of pollen with the egg cell. Seed dispersal is the movement of seeds from the parent plants to other plants with the help of insects, winds, birds, etc. It is the main reason for the dispersal of widely distributed plants.

Additional information:
-Seed formation is part of the process of reproduction in angiosperm and gymnosperm.
-The embryo develops from the zygote and the seed coat develops from the integuments of the ovule.
-These plants are dominant in lands, forests, grasslands niches, etc.
-The general meaning of the seed is anything that can be sown.
-The seeds of angiosperm are covered while in gymnosperm seeds are naked.
-Dispersal of seeds is very important for the plants to produce offspring.
-Plants have evolved various ways of seed dispersal.
-The seeds need to be landed on other plants during the favorable condition for germination and growth.
-The development of seeds is a special character of angiosperms and gymnosperms, the seed formation is absent in the case of mosses, liverworts, and ferns, but they propagate themselves only through water.

So, the correct answer is ‘Seeds'.

Note: Seeds protect and nourish the young embryo by giving food. The seeds are dispersed in various ways: by wind (anemochory, example - pine), by water (hydrochory, example - Mucuna), by animals (zoochory, example - apple), by ants (myrmecochory, example - acacias), etc. The seeds adapt according to their mode of dispersion.
