What is archespirium?
Archesporium is a cell or cell structure in a sporophyte from which spores may later develop during the alternate generation.
What process accomplishes the change from sporophyte to gametophyte?
The process that accomplishes the change from sporophyte to gametophyte is called meiosis. During meiosis, a diploid sporophyte cell undergoes two rounds of division, resulting in four haploid spores. These spores then develop into gametophytes through mitotic divisions.
What process occurs when haploid cells come together to form a diploid cell?
The process that occurs when haploid cells come together to form a diploid cell is called fertilization. During fertilization, the haploid egg cell and haploid sperm cell fuse to form a zygote, which is a diploid cell that will develop into a new organism.
Is sporophyte the stage that begins with fertilization?
No, the sporophyte stage does not begin with fertilization; it actually begins with the zygote formation, which occurs after fertilization. The zygote develops into the sporophyte through a series of growth stages. The sporophyte then produces spores through meiosis, which can develop into the gametophyte stage, completing the life cycle of plants.
What is at the top of the sporophyte?
At the top of the sporophyte in plants is the sporangium, which is a structure that produces and contains the spores. Spores are reproductive cells that can develop into a new individual in certain plants.
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.
What process accomplishes the change from sporophyte to gametophyte?
The process that accomplishes the change from sporophyte to gametophyte is called meiosis. During meiosis, a diploid sporophyte cell undergoes two rounds of division, resulting in four haploid spores. These spores then develop into gametophytes through mitotic divisions.
How does a moss sporophyte acquire nutrients in its environment?
A moss sporophyte acquires nutrients through its connection to the gametophyte, which provides it with water and nutrients through a structure called the seta. This allows the sporophyte to grow and develop in its environment.
Do the spores belong to the gametophyte or the sporophyte generation?
Spores belong to the sporophyte generation in the plant life cycle. They are reproductive structures that develop from sporangia on the sporophyte and give rise to the gametophyte generation through germination.
What process occurs when haploid cells come together to form a diploid cell?
The process that occurs when haploid cells come together to form a diploid cell is called fertilization. During fertilization, the haploid egg cell and haploid sperm cell fuse to form a zygote, which is a diploid cell that will develop into a new organism.
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 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.
Do maple tree leaves have spores?

What is Amphithecium?
The outer, "Ectodermal" cell layer of the Sporophyte in basal plants.
How many sporopytes develop from one prothallus?
One sporophyte developes from one prothallus
