The structure and function of the nucleus especially the nuclear envelope and nuclear lamina. Introduction: Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus). Organelles are structures present within a cell and are specialized to perform a particular metabolic task essential for the survival of the cell. Organelles that are enclosed by a membrane are called as membranous organelles. For example, mitochondria and nucleus. Ribosomes and centrioles are organelles that are not bound by a membrane.
