Detailed explanation-1: -All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
Detailed explanation-2: -(i) Seeds need moisture (water) and air for sprouting. If the seeds do not get the right amount of moisture and air they will not sprout at all. (ii) Seeds spread to far places as they are carried away by birds, animals, air and water from one place to another place.
