Question

enlist the function of micropyle prior to fetilization in the ovule of angiosperm .​

Answer 1

$\huge\tt{Answer:-}$

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 the micropyle, the so-called pollination drop mechanism. ... In angiosperms, only a pollen tube enters the micropyle..
