Variation of ages (otherwise called metagenesis) is the kind of life cycle that happens in those plants and green growth in the Archaeplastida and the Heterokontophyta that have unmistakable haploid sexual and diploid agamic stages. In these gatherings, a multicellular haploid gametophyte with n chromosomes interchanges with a multicellular diploid sporophyte with 2n chromosomes, comprised of n sets. A develop sporophyte produces haploid spores by meiosis, a procedure which lessens the quantity of chromosomes to half, from 2n to n. 

The haploid spores sprout and develop into a haploid gametophyte. At development, the gametophyte produces gametes by mitosis, which doesn't adjust the quantity of chromosomes. Two gametes (starting from various living beings of similar species or from a similar living being) circuit to deliver a diploid zygote, which forms into a diploid sporophyte. This cycle, from gametophyte to sporophyte (or similarly from sporophyte to gametophyte), is the manner by which all land plants and numerous green growth experience sexual generation.
