Every living thing has cells. It is the basic functional unit in humans. Humans are multi cellular organisms, which roughly have trillions of cells in the human body. They all play an important role in various bodily functions.<\/p>\n

They form the body\u2019s structure, take in and transport nutrients from foods to the host, convert nutrients to energy, and carry the genetic materials of the body. The cell, though extremely minute does have different parts on it. (1, 2<\/strong>)<\/sup><\/p>\n

How many cells are in the human body ?<\/h3>\n

Ans : Approx … 37.2 trillion cells<\/span><\/em><\/h3>\n<\/blockquote>\n

What are the different parts of the human cells? How do these parts function?<\/strong><\/em><\/p>\n

Cell membrane<\/h2>\n

It is the outer covering of the cell, which consists of proteins and lipids. It is semisolid, which aids in the movement of the cell organs to other places. It contains four molecules: carbohydrates, proteins phospholipids, and cholesterol.<\/p>\n

The functions of the cell membranes are:<\/p>\n

    \n
  1. It protects the cell.<\/li>\n
  2. It regulates the exchange of substances in and out of the cell. (1, 2, 3<\/strong>)<\/sup><\/li>\n<\/ol>\n

    Cytoplasm\/Protoplasm<\/h2>\n

    It is the fluid inside the cells, which allow a number of cell organs to float inside the cell. It contains a nucleus surrounded by a nuclear membrane. It consists of molecules, enzymes, fatty acids, sugar, and amino acids. (3<\/strong>)<\/sup><\/p>\n

    The functions of cytoplasm are:<\/p>\n

      \n
    1. It contains molecules that aid in various metabolic functions of the body and facilitates the breakdown of waste materials.<\/li>\n
    2. It gives the cell its shape.<\/li>\n
    3. It keeps the organelle in place. (3, 4<\/strong>)<\/sup><\/li>\n<\/ol>\n

      Endoplasmic Reticulum<\/h2>\n

      It consists of a network of membranes such as the tubules and vesicles. There are two kinds of endoplasmic reticulum: the rough and smooth. (4<\/strong>)<\/sup><\/p>\n
