Prokaryotic cells. Singled celled organisms. Like bacteria, fungi, plants, etc.
A baby's immune system is not fully developed until he/she is about six months-old. In the meantime, pregnant mothers pass immunoglobulin antibodies from their bloodstream, through the placenta, and to the fetus. These antibodies are an essential part of the fetus's immune system. They identify and bind to harmful substances, such as bacteria, viruses, and fungi that enter the body. This triggers other immune cells to destroy the foreign substance.
Without cell's people, animals, and plants wouldn't be able to grow or reproduce. The cell cycle makes a duplicate of the same cell making a living object grow or reproduce. How ever plants do not reproduce that is another process.
Hope this helps!!
