Learn about the comparison between Mitosis and Meiosis. Comparison # Mitosis: 1. Nuclear division and chromosome duplication: Mitosis involves one nuclear division. It is the chief process of reproduction in many unicellular organisms. Each division ensures duplication of chromosomes. 2. Chromosome number: As a consequence of mitosis daughter nuclei maintain the same number of chromosomes as before the division (diploid [...]
The following points highlight the three main types of cell division in animals and plants. The types are: 1. Amitosis 2. Mitosis 3. Meiosis. Cell Division: Type # 1. Amitosis: The amitosis or direct cell division is the means of asexual reproduction in unicellular organisms like bacteria and protozoans and also a method of multiplication or growth in foetal membranes [...]
In this article we will discuss about the meiotic division of a cell. The meiotic division includes two complete divisions of a diploid cell resulting into four haploid nuclei. The first meiotic division includes a long prophase in which the homologous chromosomes become closely associated to each other and interchange of hereditary material takes place between them. Further, in the [...]
