A cell is a structure as well as a functional unit of life. 3.Every living thing has cells: bacteria, protozoans, fungi, plants, and animals are the main group of living things. The Cell and General Physiology:  4.Some organisms are made up of just one cell are called unicellular. (e.g. bacteria and protozoans), but animals, including human beings, are multi-cellular. An adult human body is composed of about 100,000,000,000,000 cells!  Human Physiology:  In human physiology, we will explain the specific characteristics and mechanisms of the human body that make it a living being.  The very fact that we remain alive is the result of complex control systems, for hunger makes us seek food and fear makes us seek refuge. Sensations of cold make us look for warmth. Other forces cause us to seek fellowship and to reproduce. Cells as the Living Units of the Body:  The basic living unit of the body is the cell. Each organ is an aggregate of many different cells held together by intercellular supporting structures.  Each type of cell is specially adapted to perform one or a few particular functions.  Almost all cells also have the ability to reproduce additional cells of their own kind. Fortunately, when cells of a particular type are destroyed, the remaining cells of this type usually generate new cells until the supply is replenished. Cell: Cells, the smallest structures capable of maintaining life and reproducing, compose all living things, from single-celled plants to multibillion-celled animals. The human body, which is made up of numerous cells, begins as a single, newly fertilized cell. A cell consists of three parts: the (1)cell membrane, the (2)nucleus, and, between the two, the (3)cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
