Video Summary
Cells are the smallest structural and functional unit of life. All living things are made up of cells, from single-celled organisms to the largest animals. Cells have small parts called organelles that carry out vital functions necessary for a cell's life. Major organelles include: The cell membrane: surrounds and protects the cell. The nucleus: contains the DNA. The endoplasmic reticulum: helps in protein synthesis, lipids, and steroids. The mitochondria: are responsible for providing the cell with energy.
