Document Summary
Seven characteristics that all forms of life share. The fundamental unit of life is the cell. A plant can adjust the size of the pore of the surface of a leaf (a stomata) to regulate gas exchange: exhibit homeostasis: organisms are able to regulate their internal environment such that conditions remain relatively constant. Sweating is one way which the body attempts to remove heat and thereby maintain a constant temperature: growth and development all organisms increase their size by increasing the size and/or number of cells. Many organisms also change overtime: evolve: population of living organisms change over the course of generations to become better adapted to their environment. Cell theory: all organisms are composed of one of more cells. Single cells from multicellular organisms can be extracted and maintained in vitro and survive. The cell is the smallest unit that has the properties of life.
