Question

Enlist the functions of micropyle prior to fertilization and after fertilization in the ovule of angiosperms​

Answer 1

Answer:

The micropyle opening allows the pollen (a male gametophyte) to enter the ovule for fertilization. In gymnosperms (e.g., conifers), the pollen is drawn into the ovule on a drop of fluid that exudes out of themicropyle, the so-called pollination drop mechanism. In angiosperms, only a pollen tube enters themicropyle.
