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. WebIn animals, haploid cells containing a single copy of each homologous chromosome are found only within gametes. Gametes fuse with another haploid gamete to produce a …

WebSomatic cells have a diploid set of chromosomes as compared to gametes, which are produced by meiosis (reduction division) and have a haploid set of chromosomes. Many species like wheat have a varied set of chromosomes in their somatic cells, e.g. hexaploid, triploid, tetraploid, etc. Somatic cells are used for cloning by which an identical ... WebIn nearly all species of animals and some fungi, cytokinesis separates the cell contents via a cleavage furrow (constriction of the actin ring that leads to cytoplasmic division). In plants, a cell plate is formed during cell cytokinesis by Golgi vesicles fusing at the metaphase plate.
