The small opening in a plant ovule through which the pollen tube passes in order to effect fertilisation

minute opening in the wall of an ovule through which the pollen tube enters

A small seed surface opening usually found in dicot seeds where the pollen tube entered the ovule

The opening in a ripe seed through which moisture may enter prior to germination.

a small opening in the integument at the apex of a seed through which either pollen (gymnosperms) or the pollentube (angiosperms) enters

A small canal in the integument surrounding the ovule of a flowering plant, through which the pollen tube usually enters the ovule on the way to the embryo sac. Water enters the seed via the micropyle prior to germination.

Opening or mouth (orifice)of a ovule.

a small canal through the integument(s) of an ovule, persisting as a pore in the seed coat.

an opening in the surface of a plant ovule through which the pollen tube passes.

Hole through seed coat.

The micropyle is the small pore in a seed that that allows water absorption.

The end of the embryo sac where the egg cell and synergids are located.

On the surface of the egg, there is a small indention with a miniscule hole known as the micropyle. This hole allows for the developing embryo inside to respire.

The minute opening in a butterfly egg.

The micropyle is the large depression at the top of a butterfly's egg. This small pit marks where the sperm entered the egg. While the egg is developing, air and water enter the egg through the micropyle.

In nematodes: A minute opening in the membrane of an egg through which the spermatozoa enter. ( 14)
