Reproduction in Pteridophytes
Pteridophytes have a dominant sporophytic (diploid) phase that undergoes meiosis to produce spores and then comes a gametophytic (haploid) phase that undergoes mitosis to produce gametes. The gametophyte of pteridophyte bears the male sex organ called the antheridia and the female sex organ called the archegonia. Transferring the male gamete (antherozoids) to the female archegonia is achieved with the help of water. The male and female gametes then fuse to form the zygote which develops into the sporophyte that further undergoes meiosis to form the similar kind of spores (homospory).
Pteridophyta – Definition, Characteristics, Classification, Uses
Pteridophyta is a division of the kingdom Plantae that consists of plants that dominated the planet before the evolutionary appearance of seed-producing plants. Pteridophytes lack both flower and seed and reproduce mainly with the help of spores. Pteridophytes are the first group of plants that have evolved to show the vascular system.
