On the gametophyte, cells in the archegonium and antheridium form the eggs and sperm. The sperm swim to the egg and fertilize it, forming the zygote. The embryo develops into the sporophyte, still attached to the gametophyte.

What is archespirium?
Archesporium is a cell or cell structure in a sporophyte from which spores may later develop during the alternate generation.
What stage is dominant in ferns?
the Sporophyte generation
What process occurs when haploid cells come together to form a diploid cell?
The sporophyte stage! just found the answer to my homework
What does the sporophyte grow out of?
In moss, where the sporophyte grows directly out of the top of the gametophyte.
What generation is dominant in both gymnosperms and angiosperms?
gymnosperm- sporophyte angiosperm- sporophyte
What is archespirium?
Archesporium is a cell or cell structure in a sporophyte from which spores may later develop during the alternate generation.
What cell did the sporophyte develop?
On the gametophyte, cells in the archegonium and antheridium form the eggs and sperm. The sperm swim to the egg and fertilize it, forming the zygote. The embryo develops into the sporophyte, still attached to the gametophyte.
Why do gametophytes die after the sporophyte starts to grow?
The gametophyte is responsible for producing gametes, both male and female. When a male gamete fertilizes the female gamete, a zygote, or fertilized cell is created. This zygote matures and grows (through mitosis) into a sporophyte. At this point, the gametophyte has already done its job, and is not needed. Therefore it dies. The sporophyte releases spores, which eventually develop into gametophytes, and the cycle restarts.
Do maple trees have leaves?
The maple trees that you see are in the sporophyte stage of the plant life cycle. A sporophyte will produce spores which then develop into gametophytes. So, yes, maple trees have spores (if you are talking about the sporophyte stage). The sporophyte stage is part of the life cycle of all land plants.

How many sporopytes develop from one prothallus?
One sporophyte developes from one prothallus
How do you grow a fern from a spore?
Fern spores on germination produce prothalli; later on these prothalli develop the archegonia and anthredia.The sexual reproduction after fertilization of egg cell in the archegonium forms the zygote and this zygote develops in a sporophyte. This sporophyte leads an independent life and a new fern plant comes in existence from the spore.
What is Amphithecium?
The outer, "Ectodermal" cell layer of the Sporophyte in basal plants.
What is the first cell of the sporophyte generation in the life cycle of a pine tree?
the first cell in sporophytic generation is the zygote
What is the dominant generation of Bryophytes?
In vascular plants, the principal generation phase is the sporophyte, which is usually diploid with two sets of chromosomes per cell. By contrast, the principal generation phase in non-vascular plants is usually the gametophyte, which is haploid with one set of chromosomes per cell.http://en.wikipedia.org/wiki/Vascular_plants
What stage is dominant in ferns?
the Sporophyte generation
How does the gametophyte generation of a plant differ from the sporophyte generation?
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.
