Gametophyte - English Definition & Meaning

Definition

A gametophyte is the haploid (n) generation in plants and algae that exhibit alternation of generations. It produces gametes (sex cells) through mitosis, a type of cell division that maintains the chromosome number. Think of it as the gamete-producing stage of a plant's life cycle. The gametophyte is the dominant phase in non-vascular plants, like mosses and liverworts. It's a vital step in sexual reproduction, leading to genetic diversity.

Etymology

The word "gametophyte" comes from the Greek words "gamete" (sexual cell) and "phyton" (plant). The name literally means "gamete plant." This refers to its function: producing gametes. The etymology emphasizes its role in gamete formation.
