In this article we will discuss about the structure of nucleus with the help of suitable diagrams. The nucleus (Fig. 1.11) is generally a round body occupying the centre of the cell. Its shape, size, position and number vary. The nucleus may contain many lobes. Usually most mature cells possess a nucleus, but there are certain larger cells in the [...]

In this article we will discuss about the structure of nucleus. This will also help you to draw the structure and diagram of nucleus. 1. It was discovered by Robert Brown (1831). 2. It is the major part of a eukaryotic cell that contains the genetic material. Prokaryotic cells have no nucleus as such. 3. Each nucleus remains enclosed in [...]
