Suspensor cells lie towards micropylar end and divide transversally to produce a row of 7 to 8 cells called suspensor whose main function is to push in foodladen endosperm to provide nutrition to the developing embryo.
Double fertilisation is an event unique to angiosperms (monocot and dicot plants).
Emasculation is a step of artificial hybridisation where satmen are removed from bisexual flower.
A few flowering plants such as some species of Asteraceae and grasses, have evolved a special mechanism, to produce seeds without fertilisation, called apomixis.
