Reproduction and Growth topics include: Cell division modes, bacteria growth cycle and quantitative measurement. Reproduction is the process of creating new organisms that can grow. Growth is a way for living things to generate the materials needed for reproduction.  Here are some other differences between growth and reproduction: Growth: Organisms adapt to changes in their physiology, such as a child growing into an adult. Reproduction: A new organism is formed from another in the same species or family. Growth: Development of the body. Reproduction: Increase in number or formation of... Show more
