- The female gametophyte of gymnosperms is a large and multicellular structure that serves the double function of supporting the gametes as well as nurturing the growing embryo which is in contrast to the state in angiosperms, wherein female gametophyte is minute and typically eight-nucleated with a single operational gamete.

Female Gametophyte. The female cone also has a central axis on which bracts known as megasporophylls (Figure 3) are present. In the female cone, megaspore mother cells are present in the megasporangium. The megaspore mother cell divides by meiosis to produce four haploid megaspores.

Oct 31, 2023 · In angiosperms, the female gametophyte in the ovule exists in an enclosed structure, the ovary; in gymnosperms, the female gametophyte is present on exposed bracts of the female cone and is not enclosed in an ovary.
Female Gametophyte: Embryo sac. The female gametophyte of gymnosperms is a large and multicellular structure that serves the double function of supporting the gametes as well as nurturing the growing embryo which is in contrast to the state in angiosperms, wherein female gametophyte is minute and typically eight-nucleated with a single ...
- The gametophyte is the sexual phase in the alternation of generations of plants and a few algae. This stage produces gametes that undergo alternati...
- The sporophyte is the diploid phase in the plant life cycle that develops from the zygote. Sporophytes give rise to spores from which the gametophy...
- The pollen grains are released from the pollen-sacs at the two-celled stage. The generative cell further divides to form two male gametes. These ma...

- The two different types of gametophytes are- male gametophytes and female gametophytes. Male gametophytes are the pollen grains whereas female game...
- Gametophytes are haploid multi-cellular organisms. On reaching maturity, the gametophyte produces one or more gametangia. these are the organs that...
- Mosses and hornwort are some of the examples of gametophytes.
The life cycle of a gymnosperm involves alternation of generations, with a dominant sporophyte in which the female gametophyte resides, and reduced gametophytes. All gymnosperms are heterosporous. The male and female reproductive organs can form in cones or strobili.
Apr 27, 2017 · Gametophyte Definition. 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.
The female gametophyte of angiosperms develops in the ovule (located inside the female or hermaphrodite flower). Its precursor is a diploid megaspore that undergoes meiosis which produces four haploid daughter cells.
