Summary Introduction
Introduction:
All living organisms are made up of cells and its products. 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. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. The cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. The protoplasm denotes all living materials that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).
