WebDescribe the steps of meiosis I. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase, which is also called the first gap phase, is the first phase of the interphase and is focused on cell growth. The S phase is the second phase of interphase ... Web1 jun. 2010 · Meiosis is a mode of cell division specific to eukaryotic organisms whereby four haploid daughter cells are produced from a single diploid parent cell ( Villeneuve and Hillers, 2001; Hamant et al., 2006; Mezard et al., 2007 ).

Web20 nov. 2024 · Mitosis is the process by which body cells divide and create copies of themselves for growth and repair. In meiosis, the new cells have half the genetic material of the parent cell and is the process by which egg and sperm cells are formed. Difference Between Mitosis and Meiosis WebMeiosis leads to formation of cells that contain half the number of chromosome than parental cells. In ferns, these cells are the spores. So a spore is the product of meiosis in ferns. Gametes, prothallus are formed at later stages of spore germination. Protonemal cells are found only in mosses and not ferns. Hence, answer is "Spores" north minnesota cabins

WebMeiosis is a kind of cell division that results in the production of four gamete cells and a halving of the parent cell's chromosome count.
