  • Mitosis is the process that undergoes a cell to give two new identical cells. This is how our body makes or renovates tissues.
  • The nucleus is the part of the cell that contains the DNA, which is necessary to synthesize the proteins that the cell and our body need. It is in the center of the cell and has a nuclear membrane that separates it from the rest of the organelles.
  • The cytoplasm is a solution that surrounds the nucleus, and it contains the rest of the organelles that the cell needs for its functions.
  • The cell membrane is the structure that encloses all the cytoplasm and the nucleus. It is made of phospholipids, proteins, and cholesterol, which allows the passage of certain substances.
