Gametophyte - Wikipedia
A gametophyte (/ ɡ ə ˈ m iː t ə f aɪ t /) is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae.
Gametophyte | Definition & Examples | Britannica
gametophyte, in plants and certain algae, the sexual phase (or an individual representing the phase) in the alternation of generations—a phenomenon in which two distinct phases occur in the life history of the organism, each phase producing the other.
What is Gametophyte? - Male Gametophyte, Female Gametophyte…
The gametophyte is a stage in the life cycle that is found in all plants and certain species of algae. This process includes both multicellular diploid generation known as Sporophyte and a multicellular haploid generation known as Gametophyte.
Gametophyte - Definition, Function and Examples - Biology …
2017年4月27日 · Gametophytes are the stage which produces sex cells in plants and algae that undergo alternation of generations. Among land plants, these sex cells may be referred to as “sperm” and “eggs,” with “male” and “female” sex cells combining to produce offspring.
Plant Life Cycles: Gametophyte and Sporophyte Stages Detailed
2024年8月2日 · The gametophyte stage represents a fascinating phase in the life cycle of plants, characterized by its role in sexual reproduction. This stage is marked by the production of gametes—sperm and eggs—through mitosis.
Gametophyte Structure and Sporophyte Generation - ThoughtCo
2018年4月28日 · A gametophyte represents the sexual phase of the plant life. This cycle is named alternation of generations and organisms alternate between a sexual phase, or gametophyte generation and an asexual phase, or sporophyte generation.
Gametophyte - Encyclopedia.com
2018年5月23日 · A gametophyte, or gamete-bearing plant, is one of the two multicellular phases that occur in alternation of generations. The gametophyte is the haploid phase; that is, its cells contain only one set of chromosomes, in contrast to the sporophyte phase, where the cells contain two sets.
The Difference Between a Sporophyte and Gametophyte
2019年7月11日 · The plants’ haploid phase is called the gametophyte, and the diploid phase is called the sporophyte. Offspring alternate from diploid sporophytes to haploid gametophytes and back again in generations. This means plants generate two different kinds of plants with the same genetic material.
Biology for Non-STEM Majors - Fiveable
Gametophytes are the haploid stage in the life cycle of plants, which produces gametes through mitosis. This generation is crucial for the sexual reproduction of seedless plants, where the gametophyte develops from spores and ultimately leads to fertilization and the formation of a diploid sporophyte.

Describe how the male gametophyte is formed. Describe how the female gametophyte is formed. List which cells unite during double fertilization. Explain how the embryo goes through developmental stages that are identified according to the developing embryo’s shape.
