Examples of gametophyte
gametophyte
The kelp life cycle involves a diploidsporophyte and haploid gametophyte stage.
From the en.wikipedia.org
The sporophyte is short-lived and remains dependent on its parent gametophyte.
From the en.wikipedia.org
The spores are therefore once again haploid and develop into a haploid gametophyte.
From the en.wikipedia.org
In many plants the gametophyte is not only small-sized but also short-lived.
From the en.wikipedia.org
The bryophyte life-cycle is strongly dominated by the haploid gametophyte generation.
From the en.wikipedia.org
A tiny gametophyte develops inside the wall of a microspore, producing a pollen grain.
From the en.wikipedia.org
The horn-shaped sporophyte grows from an archegonium embedded deep in the gametophyte.
From the en.wikipedia.org
In flowering plants, cells of the gametophyte can undergo this process.
From the en.wikipedia.org
Unlike the seed plants, the pteridophytes have a gametophyte stage that is free-living.
From the en.wikipedia.org
- The gamete-bearing individual or phase in the life cycle of a plant having alternation of generations
- A gametophyte is the haploid, multicellular phase of plants and algae that undergo alternation of generations, with each of its cells containing only a single set of chromosomes.
- The plant (or the haploid phase in its life cycle) which produces gametes by mitosis in order to produce a zygote
- (gametophytic) In this system, the sterility/fertility reaction is imparted to the pollen by the genetic constitution of the pollen itself and is controlled by a single gene which may have large numbers of allelic forms.
- A plant bearing sexual organs; in ferns a small discrete plant, very different from the sporophyte, also known as the prothallus. cf. sporophyte
- The phase of the life cycle of sexually reproducing plants and algae in which the gametes (egg and sperm) are produced. The gametophyte arises from the germination of a haploid spore.
- The haploid generation of plants which produce eggs and sperm
- In plants, the haploid structure that produces gametes. It contrasts with sporophyte.
- The part of the life cycle of plants having haploid nuclei and giving rise to the sex cells that on fusing produce a diploid stage, usually the sporophyte.
