Explain life cycle of pteridophytes ?
Life Cycle of Pteridophyta:
Vegetative reproduction of Pteridophyta is by rhizome. Rhizome grows all of direction as colony. Pteridophyta have life cycle known as metagenesis with two generations, they are sporophyte and gametophyte generations.
Sporophyte Generation: Sporophyte generation producing spores is a Pteridophyta itself. So, the Pteridophyta that we see in daily life is sporophyte generation. This generation is longer than gametophyte. Sporophyte can grow and produce some bud in order to add new individual. It is called asexual reproduction. While the spores is exited from sporangium and spread by wind, if it fall in suitable place it will grow as new individual plant that called as protalium.
Gametophyte Generation: Gametophyte generation is producing gamet known as protalium. Protalium is talus formed have 1-2 cm approximately in size. This form like a heart that is usually lives in moist place. Unlike Bryophyta, gametophyte in Pteridophyta only lives on some weeks. Protalium formed antheridium as male gamet and archegonium as female gamet. Antheridium produce sperm while archegonium produce ovum. Fertilization between sperm and ovum formed zygote. Furthermore, zygote will grow as new Pteridophyta that have roots, stems, and leaves.
