Cells are marvelous and incredibly complicated living things. They are self-sufficient and function like a miniature chemical factory. We think we understand it, but the more we research into the cell, the less we find that we know. The amount of coded knowledge, practical technology, systems management, manufacturing specialties, storage, and maintenance that goes on every moment in the living human cell is astounding. Yet it is only one-thousandth of an inch across.
For example, the cell membrane is a wonder in itself. If it were too porous harmful solutions would enter and cause the cell to burst. On the other hand, if the membrane were too impervious, nourishment could not come in and waste products would not be able to be expelled, and the cell would quickly die. This outer covering of the cell, in some way decides what shall enter and leave the cell. The nucleus is the largest single part of the cell and contains the chromosomes. Enclosed within a double-membrane wall, the nucleus is the command and control center of the cell.The nucleus is were the crucially-needed ribosomes are assembled. The chromosomes are the master blueprint of the cell, the DNA is located here. Mitochondria are the bean-shaped bodies that manufacture ATP (adenosine triphosphate) which is stored within. Mitochondria are the storage batteries which provide energy for the cell. Golgi bodies are curved “Q-tips” that package and distribute proteins made elsewhere in the cell. Endoplasmic Reticulum sounds like an alien creature, but actually these are both protein storage warehouses and street boulevards for their transportation to other areas in the cell. Most of the protein-manufacturing ribosomes in the cell are attached to them. Centrioles are vital to cell division process (mitosis). Vacuoles are fluid-filled, membrane-surrounded cavities inside a cell. Without any special shape or size, they are used for a variety of miscellaneous storage needs.
The human body contains about 10 trillion (10,000,000,000,000) brain, nerve, muscle and other types of cells. How marvelous these cells work together to make a complete organism. Ever wonder how the brain that is made up of specialized cells retains the knowledge we learn about. The human brain has been called the most complex object in the world. A hundred billion neurons with close to a quadrillion connections between them and yet we do not understand a single cell. We are definitely “fearfully and wonderfully made” by the Creator. (Psalm 139:14)
