Vedclass · Answer

$I, II, III \;and \;IV$ are correct Flowering plants have developed many devices to discourage self-pollination. In some species, pollen, releases and stigma receptibility is non-syncronised, ie, either the pollen is released before the stigma becomes receptive or stigma becomes receptive much before the release of pollen.In some other species the anther and stigma are placed at the different positions so that the pollen can not come in contact with the stigma of same flower: Both these devices prevent autogamy.
