But remember, if a high stress level continues for a long period of time, or if potential problems from stress continue to interfere with activities of daily living, it is important to reach out to a licensed mental health professional, such as a psychologist.
Noun. 1. meiosis - (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants). miosis, reduction division.
In most plants meiosis and fertilization divide the life of the organism into two distinct phases or generations. The gametophyte generation begins with a spore produced by meiosis. The spore is haploid, and all the cells derived from it (by mitosis) are also haploid. In due course, this multicellular structure produces gametes â by mitosis â and sexual reproduction then produces the diploid sporophyte generation.
