▫️Alternation of generation is observed in pteridophyte.

▫️In pteridophyte, sporophytic and gametophytic generation are independent of each other.

▫️Due to this unique character in pteridophyte, the both generation are equally distributed over a plants life and hence “alternate”.

Answer:

Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages. In these groups, a multicellular gametophyte, which is haploid with n chromosomes, alternates with a multicellular sporophyte, which is diploid with 2n chromosomes, made up of n pairs. A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n.
