BVP MedicalBVP Medical 2009

Solution:

In pteridophytes, spore is a haploid structure. which develops after meiosis in the spore mother cell. On germination, it gives rise to a green haploid prothallus (gametophyte) which is monoecious, ie, has both antheridia ;male sex organs) and archegonia (female sex organs).
