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).

Gametophyte size ranges from three cells (in pollen) to several million (in a lower plant such as moss). Alternation of generations occurs in plants, where the sporophyte phase is succeeded by the gametophyte phase. The sporophyte phase produces spores by meiosis within a sporangium.The gametophyte phase produces gametes by mitosis within an antheridium (producing sperm) and/or archegonium (producing eggs).These different stages of the flowering plant life cycle are shown in Figure 4.ametophyte size ranges from three cells (in pollen) to several million (in a lower plant such as moss).
