$<i>$
Micropyle plays a significant part in the germination of the seed.

To start with, the pollen tube reaches the ovule to deposit the sperm for fertilization from the micropylar end.

Secondly at the time of germination of the seed the micropyle assists in the function of water absorption and finally the roots emerge through the micropyle during seeds germination.

The hilum of a liberated seed is a small scar marking its former place of attachment. The short ridge (raphe) that sometimes leads away from

the hilum is formed by the fusion of seed stalk and testa. In many seeds, the micropyle of the ovule also...

Answer 2

Microphyle(Botany):-a small opening in the surface of an ovule, through which the pollen tube penetrates, often visible as a small pore in the ripe seed.

The micropyle helps in absorbing the water at the time of germination of the seed.
