Answer 2

This procedure is called Self-fertilization. In self-fertilization, blossoms trade dust with same bloom or another bloom on a similar plant. Any remote dust that lands on a blossom from an alternate bloom are rejected.The pistil has the ability to recognise pollen, whether it is of right type (compatible) or of the wrong type (incompatible). It is mediated by chemical components of the pollen interacting with those of the pistil.
