Are microspores and megaspores produced by mitosis or meiosis?
Microspores and megaspores are produced by meiosis. In plants, microspores develop into male gametophytes (pollen), while megaspores develop into female gametophytes (embryo sacs). This process occurs in the reproductive structures of seed plants, where diploid sporophytes undergo meiosis to produce these haploid spores.
Can haploid cells undergo mitosis?
No, haploid cells cannot undergo mitosis. Mitosis is a type of cell division that occurs in diploid cells, which have two sets of chromosomes. Haploid cells only have one set of chromosomes and undergo a different type of cell division called meiosis.
What is the process of pollen production?
Pollen is produced in the anthers of flowers through a process called microsporogenesis. It begins with the division of microspore mother cells, which then undergo meiosis to produce haploid microspores. These microspores further develop into pollen grains, which contain the male gametes necessary for plant reproduction.
Are spermatagonia haploid or diploid?
Haploid. They may be diploid when they are first formed, but by the time they undergo all the stages of mitosis, they are haploid.
Does mitosis occur in germ cells?
NoGerm layers produce haploid cells.For this they should undergo meiosis
Can germ cells be involved in mitosis?
No, germ cells undergo meiosis to produce haploid gametes (sperm and egg cells), not mitosis. Mitosis is the process of cell division that produces genetically identical daughter cells for growth and repair in somatic cells.
Daughter cells produced when cells undergo mitosis are genetically and daughter cells produced when cells undergo meiosis are genetically .?
Identical, different.
Why must gametes undergo meiosis instead of mitosis?
Gametes don't undergo Meiosis, but are CREATED in Meiosis.Gametes should be haploid. Otherwise chromosomal number will be doubled in offspring
What generation undergo mitosis in a sporic life cycle?
both the haploid and diploid generations
Is the end product of mitosis haploid or diploid?
Mitosis produces DIPLOID cells- remember in mitosis your INCREASING the number of CELLS but the chromosome number is the SAME as the parentso a parent that has a (DIPLOID number of 10)will produce at the end of mitosis will produce 2 children with a diploid number of (10)That is why Mitosis is CONSERVATIVE.So in actuality, 1 diploid cell will produce 2 diploid cells in mitosisThe above is only true if the starting cell is itself diploid. However there are plenty of instances, especially in plants, in which cells that are haploid (the ones that give rise to pollen and egg, and endosperm nuclei, for example) or multiploid (hexaploid wheat, for example) undergo mitosis, and the cells that are produced have the same ploidy as the starting cell. Always. As noted above, mitosis is conservative. However, you ought not assume that you started with a diploid cell.
The diploid cells that eventually give rise to haploid sperm are known as?
spermatogonia. These are the diploid cells found in the testes that undergo mitosis followed by meiosis to produce haploid sperm cells.
Do only animals undergo mitosis?
noEvery organism with a nucleus can undergo mitosis. Prokariyotes cannot undergo mitosis
