Where did dissemination occur in lower plants during the sporophyte generation?
Dissemination occurs in lower plants during the sporophyte generation in ferns. This would happen then so the spores could blow away.
During the life cycle of a plant gametophyte is to n as sporophyte is to?
Basically, plants have two stages in their life cycle, they can appear as a gametophyte or a sporophyte.
What are the two stages of plant life?
Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle. The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle. This is much easier to understand if you see a diagram.
does the sperm cell come from male or female?
Gametes come from both the mother and the father. The mother's gamete is known as an egg and the father's gamete is known as a sperm.
What is the correct order in which these structure form during the plant reproduction process?
Plants have two phases during reproduction: sporophyte and gametophyte. The sporophyte is doploid and the gametophyte is haploid. Plants cycle between these seasonally.
What is a gametophyte?
A gametophyte is an organism in the life cycle of a plant that produces haploid gametes. It is the sexual phase of the plant life cycle and is the first stage in the alternation of generations between the gametophyte and sporophyte generations. The gametophyte produces male and female gametes, which are haploid cells that fuse to form a diploid zygote. The zygote develops into the sporophyte generation, which produces haploid spores that divide to form the next generation of gametophytes.
What is archespirium?
Archesporium is a cell or cell structure in a sporophyte from which spores may later develop during the alternate generation.
In what stage does the plant produce spores?
Plants produce spores during the gametophyte, or haploid, stages. Spores are the sex cells for the plant. The spores will then germinate and produce new plants.
During alternation of generations cells reproduce by what?
both meiosis and mitosis.
Do bryophytes produce seeds?
Yes, bryophytes produce pollen, but they also produce spores through alternation of generations. During the haploid (N) gametophyte stage of the pant's life, eggs and sperm are produced. The eggs are fertilized to form a diploid (2N) sporophyte plant which produces spores.
How many spores are in a capsule?
1
What do gametophyte produce during a plant life cycle?
The gametophyte produces gametes.
