WebIn many animals, the germ cells originate in the primitive streak and migrate via the gut of an embryo to the developing gonads. There, they undergo meiosis, followed by cellular differentiation into mature gametes, either eggs or sperm. Unlike animals, plants do not have germ cells designated in early development. http://www.differencebetween.info/difference-between-meiosis-in-plant-and-animal-cells listworthy

WebMeiosis I : Reductional Cell Division Sexual reproduction in organisms takes place through the fusion of male and female gametes, the sperm and the egg respectively. Gametes are haploid in nature, i.e., they contain only half the number of chromosomes. This genetic content makes them different from other body cells. WebFeb 10, 2024 · In animal cells, centrosomes are treated very much the same way as DNA. Each daughter cell gets one centrosome from the parent cell during cell division. The centrosome is then copied during the cell cycle, so that the cell can give one to each daughter cell when it divides.
