Double fertilization is a complex fertilization mechanism of flowering plants. This process involves the joining of a female gametophyte with two male gametes. It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower.
Following the treatment, the Fetal Stem Cells will travel throughout the body, detecting damaged cells and tissue and attempts to restore them. The Fetal Stem Cells can also stimulate existing normal cells and tissues to operate at a higher level of function, boosting the body’s own repair mechanisms to aid in the healing process. These highly adaptive cells then remain in the body, continually locating and repairing any damage they encounter.
Cnidarians were the first phylum that scientists saw tissue level organization in. Tissue level organization meaning cells all of one type start to function in a unified way.
