  Meristems are tissues within a plant that are undifferentiated-that is, they have no defined identity like being "leaf tissue" or "stem tissue". I think this is analogous to stem cells in animals; they can turn into a number of different types of cells and tissues depending on chemical and environmental cues. Meristems are the location of growth for plants including the root, base of roots, stems, flowers, and leaves. There are specific names for these types of meristems. For example, root (or shoot or floral) apical meristem and basal meristem. 

There are two major types of meristems: primary and secondary. Primary meristems are tissues that make the plant taller, or a plant's appendages (e.g. branches) grow longer. Secondary meristems make a plant fatter. Not all plants have secondary meristems, namely most monocots (corn and grass fall into this group). Dicots, like a maple tree, undergo this lateral growth that gives it wood and bark.
