Question

briefly describe the life cycle of an advanced pteropsida?​​

Answer 1

Life Cycle of Pteridophytes:

• There is alternation of generation in the lifespan of pteridophytes. This is known as metagenesis. Just like in the seed bearing plants and mosses there is a diploid generation alternating with a haploid generation.

• The diploid generation is the sporophyte which produces the spores.

• The haploid generation is the gametophyte which produces the gametes.

• Both the sporophyte and gametophyte are independent and free living.

• Introduction to Pteropsida (Ferns):

Pteropsida represent the most highly evolved group among the lower vascular plants. In this group are included some of the most beautiful, and most familiar plants called Ferns which are the joy and pride of a gardener.The delicate, varied and highly attractive foliage of ferns have made them a must in any garden. Of all the pteridophytes, ferns are the most widely distributed. The living ferns are represented by 305 genera and nearly 10,000 species.
