The pronghorn (Antilocapra americana) is a species of artiodactyl mammal indigenous to interior western and central North America.
Palynology is the study of the pollen grain produced by the seed plant (Angiosperm and gymnosperm) and spores produced by Pteridophytes, Bryophytes, algae and fungi (Moore et al ., 1991). In present study Pollen analysis of Pollen loads were done to determine the beeflora of area under study.alynology is the study of the pollen grain produced by the seed plant (Angiosperm and gymnosperm) and spores produced by Pteridophytes, Bryophytes, algae and fungi (Moore et al ., 1991).

1 It is flanked by. 2  2 synergid cells. 3  In several (perhaps all) angiosperms, they secrete an attractant that guides the pollen tube through the micropyle into the embryo sac. 4  The large central cell, which in most angiosperms contains 2 polar nuclei, will after its fertilization develop into the endosperm of the seed.n angiosperms, meiosis in the sporophyte generation produces two kinds of spores. 1  microspores. 2  which develop in the microsporangium and. 3  which will germinate and develop into the male gametophyte generation and. 4  megaspores.
