The cell.
We are made out of cells. The cells have many are found everywhere in our body and can also be found in plant. They are twotypes of cells Eukaryotes and Prokaryotes. Prokaryotes were the first living organism on earth, and they are single cell organisms. Theprokaryotes have not developed, so they do not have as much organelles as the eukaryotes therefore they are primitive. These only have onechromosome and no nucleus. While the Eukaryotes are divided into two sub groups which are plants and animals. These are can have a variety ofthings. Both of the cells prokaryotes and eukaryotes have organelles that have specific functions to help the cell. For example cell wallonly the plant cell has that and not the animal cell. Cells are so small that millions can fit on the top of a needle. The cell goesthrough a cell cycle called Meiosis needs to happen to restore the cell, or if the cell is damaged it can eliminate itself to so a new cellcan take over. It is has many steps but it all can occur in a very brief time. The cell can send messages with each other to help restoreor renew an entire new cell for the growth and stability of the individual. Cells contain genetic material which is most commonly known asDNA, which is all the genetics and traits of the individual. DNA is a double stranded helix that contains instructions for that individual.
