Embryogenesis is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum, egg, which, after fertilization, is then called a zygote. The zygote undergoes rapid mitotic divisions, the formation of two exact genetic replicates of the original cell, with no significant growth (a process known as cleavage) […]

The following article will guide you about how do amoeba reproduce asexually during favourable and unfavourable environmental conditions. Binary Fission: This is the commonest and simplest method of reproduction in amoeba. In this, the whole body divides, like an ordinary cell, into two daughter amoebae by mitosis. Hence, it is termed binary fission. In favourable […]

The following article will guide you about how do Paramecium reproduces asexually by transverse binary fission and also undergoes several types of nuclear reorganization. Transverse Binary Fission: During favourable conditions, the paramecium reproduces by transverse binary fission. Before division, the animal stops feeding and the oral groove and buccal structures begin to disappear. The micronucleus […]
