Do plants use mitosis or meiosis? Gametophytes produce gametes by mitosis. In animals, meiosis produces sperm and egg, but inplants, meiosis occurs to produce the gametophyte. The gametophyte is already haploid, so it produces sperm and egg by mitosis. How do plant cells go through mitosis?
Do somatic cells make gametes? Sperm and egg: Gametes or gametic cells are sperm cells in men and egg cells, or ovum, in women. The sperm is the smallest cell in the human body. The ovum is the largest cell found in the human body. ...

Spores are produced asexually or sexually and provide a dispersal and/or survival function for the fungus. The size, shape, color, and genesis of spores are also used as taxonomic criteria. Asexual reproduction Asexual reproduction, the result of mitosis, results in progeny that are genetically ...
Do somatic cells make gametes? Does mitosis produce somatic cells or gametes? Do somatic cells reproduce asexually? Are all somatic cells produced by mitosis? Do germline cells create somatic cells? Can meiosis occur in somatic cells? Does a zygote produce somatic cells by mitosis? Are diploid ...
Which cells do not undergo meiosis? All Answers (5) In multi cellular plants and animals, however, meiosis is restricted togerm cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes ( the ...
It may be preceded by a premeiotic endomitosis (Dawley and Bogart, 1989) or include an endomeiosis without separation of the two cells and followed by a gathering of the two chromosomal sets (Simon et al., 2003). This gathering may also concern two cells resulting from distinct meioses....
The real impact of nanoparticles on male fertility is evaluated after a careful analysis of the available literature. The first part reviews animal models to understand the testicular biodistribution and biopersistence of nanoparticles, while the second
