is pollen produced in pteridophytes
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).

If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. pollen tube is produced, which grows into the nucellus to provide nutrients for the developing sperm cells. Sperm cells of Pinophyta and Gnetophyta are without flagella, and are carried by the pollen tube, while those of Cycadophyta and Ginkgophyta have many flagella.
