A cell, in biology, is the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function, becoming a building block of a multicellular organism.

Let us make an in-depth study of the structure and functions of cell. After reading this article you will learn about: 1. Comparison of Prokaryotic Cells and Eukaryotic Cells and 2. Structure and Components of a Human Cell. Cell is a compartment where all the activities of life takes place.

The goal of this tutorial is for you to be able to describe cell theory, differences between prokaryotic and eukaryotic cells and understand cell structure and function.

cell theory that emphasised the unity underlying this diversity of forms, i.e., the cellular organisation of all life forms. A description of cell structure and cell growth by division is given in the chapters comprising this unit. Cell theory also created a sense of mystery around living phenomena, i.e., physiological and behavioural processes.

The cell structure comprises individual components with specific functions essential to carry out life’s processes. These components include- cell wall, cell membrane, cytoplasm, nucleus, and cell organelles. Read on to explore more insights on cell structure and function. Cell Membrane. The cell membrane supports and protects the cell.
