Cell and Molecular Biology

Every known living entity has a cell as its fundamental structural and functional element. It is frequently referred to as the foundation of life since it is the tiniest piece of life that may be considered a living entity. There are roughly 10 trillion cells in an adult human. Only under a microscope can one see the majority of plant and animal cells, which range in size from 1 to 100 m. In 1665, Robert Hooke found the cell. All organisms are made up of one or more cells, According to the cell theory, which was first put forth in 1839 by Matthias Jakob Schleiden and Theodor Schwann. It also states that all cells are descended from preexisting cells, that vital functions of an organism take place within cells, and that all cells contain the genetic information required to control cell functions and pass information to the next generation of cells.
