The cell is the basic unit of life. Eukaryotic cells have a true nucleus, membrane-bound organelles, and multiple linear chromosomes. These structures are partitioned and carry out specific functions that make a cell an organized and functional unit. The nucleus houses the chromosomes that direct and are responsible for protein synthesis. The chromosomes are made up of DNA which contains the genetic material or hereditary information that could be passed on. Other organelles such as the Endoplasmic reticulum, ribosomes, Golgi apparatus, and mitochondria have different functions including transport, modification of proteins, and generating energy throughout the cell. Cells can also maintain homeostasis or stabilize their internal environment from the external changes to prevent any damage.
