Are all animals diploid?
No, not all animals are diploid. Some animals, like nematode worms and some insects, can have variations in their ploidy levels. For example, some species of insects exhibit haplodiploidy, where males are haploid and females are diploid.
Basic kind of life cycle found in the simplest animals?
Live, eat, reproduce, die.
Do Amanita muscaria reproduce asexualy?
Because the Amanita muscaria reproduces with spores, it reproduces sexually. The spores are called basidiospores. The spores are spread by wind, and also by animals ingesting the mushrooms and spreading the spores in their waste.
What stage of the fern life cycle is dominant?
The sporophyte stage is dominant in the fern life cycle. It is the visible, leafy plant that produces spores through meiosis. The gametophyte stage is much smaller and less conspicuous, developing from the spores and producing the reproductive gametes.
How does fertilization restores the diploid number of chromosome in an orgaism with a haploid chromosome of 8 how many chromosomes are present in the spermatogonium?
Fertilization restores the diploid number by combining one haploid gamete from the mother with one haploid gamete from the father to form a zygote with the full diploid set of chromosomes. In an organism with a haploid chromosome number of 8, each spermatogonium would have 16 chromosomes because they are diploid cells that undergo mitosis to produce sperm cells with the haploid number.
What cells divide by meiosis to produce male and female spores?
In plants, meiosis occurs in specialized cells called sporophytes, which are diploid. These sporophyte cells undergo meiosis to produce haploid spores—male spores (microspores) in the anthers and female spores (megaspores) in the ovules. In fungi, similar processes occur where specialized diploid cells, known as sporogenous cells, divide by meiosis to produce spores.
What does a diploid cell inside a basidium produce as a result of meiosis?
A diploid cell inside a basidium produces four haploid spores as a result of meiosis. These spores can germinate to form new haploid organisms.
Compare and contrast plants and animals?
Plants Alteration of generations Meiosis produces spores Animals Diploid Meiosis produces gametes
In what stage does the plant produce spores?
The plant produces spores during the reproductive stage, known as the sporophyte stage in the plant life cycle. Spores are typically produced in structures like sporangia or sori and are responsible for reproduction in plants such as ferns and mosses.
Spores are produced by what in the diploid phase?
Spores are produced by the sporophyte in the diploid phase of a plant's life cycle through meiosis. The sporophyte is the multicellular, diploid phase of a plant that produces haploid spores as part of its reproductive process. These spores will eventually develop into the gametophyte phase of the plant.
What structure directly precedes the development of both a male and female gametophyte?
The development of both a male and female gametophyte is preceded by meiosis, where a diploid sporophyte cell undergoes two rounds of division to produce haploid cells called spores. These spores then develop into the gametophytes through mitotic division.
The diploid generation of the plant life cycle always?
produces spores! :)
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.
Compare the haploid life cycle found in chlamydomonas with a diploid life cycle?
In the haploid life cycle of Chlamydomonas, the organism exists as a single-celled haploid individual that produces gametes through mitosis. After fertilization, it forms a diploid zygote that undergoes meiosis to produce haploid spores, completing the life cycle. In a diploid life cycle, the organism exists as a diploid individual that undergoes meiosis to produce haploid gametes, which fuse to form a diploid zygote that develops into a multicellular diploid individual.
What produces spores in the diploid phase?
By meiosis in the sporogenous cells of the sporangium.
Spores are produced by what in diploid phase?
By meiosis in the sporogenous cells of the sporangium.
What spores are produced in the diploid phase?
By meiosis in the sporogenous cells of the sporangium.
