Name one kind of cell found in the human body?
Cells are the basic unit of structure and function in living organisms. They come in many shapes and sizes and can be single-celled or multi-celled. Cells contain genetic material, DNA, that is passed from generation to generation.
Cells: The Building Blocks of Life
Cell Theory: A core scientific principle that states that cells are the fundamental unit of life, all living things are composed of one or more cells, and all cells come from pre-existing cells. Organelle: Specialized structures within a cell that perform specific functions. Examples include mitochondria, the nucleus, and the cell membrane. Cell Division: The process by which a single cell divides into two daughter cells. This is an important process for growth, repair, and reproduction in living organisms.
Cells can recognize one another by smell. They can detect chemicals called pheromones, which act as signals between cells. Certain cells in the brain can live up to a hundred years. Cells communicate with each other using a language of electrical and chemical signals called synaptic transmission.
