Differentiate between microsporogenesis and megasporogenesis.
MicrosporogenesisMicrosporogenesisIt is a meiotic formation of haploid microspores from diploid microspore mother cell.It is meiotic formation of haploid megaspores from diploid megaspore mother cell.All the four microspores of a spore tetrad are functionalOnly one megaspore of a tetrad is functionalA large number of microspore mother cells are functional in a microsporangiumGenerally a single megaspore mother cell is functional in a megasporangium
