Cell and its Function - Medical Transcription - Lesson 8a
The fundamental unit of every animal or plant is cells. Combination of cells is called TISSUES. Every ORGAN in the body is made up of combination of many tissues. SAMENESS OF THE CELLS: All cells are same and they contain a gelatinous substance made up of or composed of water, protein, acids, fats, and various minerals. See the figure-1 and 2, to know the cell and its structures photographically.Now we see each and every part of the cell one by one. 1. CELL MEMBRANE: Cell membrane protects the cell and surrounds it that passes into and out of the cell. 2. NUCLEUS: The nucleus controls the structure of the cell. Cell reproduction process is directed by the nucleus only and which determines the function of the cell and the structure of the cell. 3. CHROMOSOMES: These are rod-like structures inside the cell. Human body cells (other than sex cells, the egg, and sperm cells) contain 23 pairs of chromosomes. Sex cells, such as sperm and egg cells have 23 single chromosom...
