for ex Hypanthodium. wht is this???
hypanthodium is an infloroscence…
as in case of composite fruits….

Question are very helpful & provide lot’s of information .
please publish more question on this site.
it is really tough to answer within 40sec.
It is slight tough to compete it…
answer of Q 15 should be option D i.e ABSENT not THIN
Thanks Ruchi,
The Structure of Microspore or Pollen Grain where
Cell wall of microspore consists of two layers, outer (exine) and inner (intine). Outer exine is made up of sporopollenin.
Three weak points are present upon the exine, where the exine is either weak or absent which is called germ pores.
no ruchi if you use your government text book just refer that diagram of DEVELOPMENT OF MALE GAMETOPHYTE the first diagram…!!!
