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 [...]
Some of the major function preformed by vacuoles in all cell organisms are as follows: Vacuole is an important organelle which is present in the cells of plants, animals, protests, fungi and bacteria see Fig. 2.8. These cell organelles along with water contain different organic/inorganic molecules. Vacuoles used to contain a variety of enzymes. Apart from water and inorganic/organic molecules, [...]
Structural units of Cell: Membranes, Microtubules and Granules! Previously, the structure of the cell was thought to be as two-phase system, consisting of nucleus and cytoplasm. It was realized that the two phases functioned as an integrated whole and contained within them various organoids such as nucleoli, mitochondria and paraplasm or Golgi complex embedded in a semifluid medium. Thus, cell [...]
