Name one kind of cell found in the human body?
"7.12(D)
7.12(F)"
Learning objective:
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.
Concepts:
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.
