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.

    Structure of Nucleus. Nucleus is a membrane bound structure that contains the cell’s hereditary information and controls the cell’s growth and reproduction.; Nucleus is present in all eukaryotic cells, they may be absent in few cells like the mammalian RBCs. The shape of the nucleus is mostly round, it may be oval, disc shaped depending on the type of cell. Start studying Cell Nucleus Structure & Function.

    Organelle Structure and Function. Organisms are composed of cells, and these cells have specific structures within in them that allow them to carry out their functions. These structures are called Organelles. The fine detail of the cell (which may be revealed by an electron microscope) is called the cell’s ultrastructure.
