The miracle of meristems

Both cell enlargement and cell division occur in specific regions. In other words, growth does not occur randomly throughout a plant. Ask your students how they think plants grow. From the top? From the side? Meiosis, reproductive cell division, takes place in the reproductive structures, or the flowers. We will learn more about sexual reproduction later in the course. Mitosis primarily takes place in growth regions called meristems (Gr. meristos = divided). There are several types of meristems located in different parts of the plant body. In the regions adjacent to these meristems, the newly divided cells undergo the process of cell enlargement. Let's look at the different types of meristems.
