Question

Differentiate between the following:

Homosporous and heterosporous pteridophytes

Solution 1

Homosporous and heterosporous pteridophyte

  Homosporous pteridophytes Heterosporous pteridophytes
  In this pteridophytes only only one kind of spore is produced  In these pteridophytes two kinds of spores are produced
  The spores are equal in size The smaller spores are called microspores and larger spores are called megaspores
  The spores are produced from the same sporangia The microspores are produced fromthe microsporangia and the megaspores are
  The spores develop one kind of gametophyte The microspores develops into male gametophyte whereas the megasspore develops into female gametophyte
  Spores germinate in soil and produce independent gametophyte Spores germinate within sporangia and produce dependent gametophyte
  eg. Lycopodium  eg. Selaginella Salvinia

Solution 2

Homosporous and heterosporous pteridophyte

  Homosporous pteridophytes Heterosporous pteridophytes
  In this pteridophytes only only one kind of spore is produced  In these pteridophytes two kinds of spores are produced
