	Meristem - Wikipedia, the free encyclopedia
		The most general form of meristem is the apical meristem (also called terminal meristem), found in buds at the tips of shoots, and at the root tip, and responsible for shoot and root growth, respectively.
		Meristems located at a bud on a branch or shoot are known as a node.
		Root apical meristems are not readily cloned, however.

	Apical meristem - Wikipedia, the free encyclopedia
		The apical meristem, or growing tip, is a completely undifferentiated meristematic tissue found in the buds and growing tips of root in plants.
		Apical meristems are very small, compared to the cylinder-shaped lateral meristems.
		The root apical meristem is covered by the root cap, which protects the apical meristem from the rocks, dirt and other pathogens.

	meristem
		Meristems found in the tip of roots and stems, the apical meristems, are responsible for the growth in length of these organs.
		The cambium is a lateral meristem that is responsible for increase in girth in perennial plants.
		Meristem culture involves growing meristems taken from shoots on a nutrient-containing medium, and using them to grow new plants.

		MERISTEM [meristem], a specialized section of plant tissue characterized by cell division and growth.
		In one type of lateral meristem, called cambium, or vascular cambium, the cells divide and differentiate to form the conducting tissues of the plant, i.e., the wood, or xylem, and the phloem (see bark ; stem).

		They are actively growing meristems that differ clearly from apical meristems and are located between more or less differentiated tissues usually at the base of each internode.
		A meristem does not only include the initial cells and their immediate progenitors, but also some parts of the shoot.
		The situation is similar in root meristems, although their anatomy is different.

	Growth from apical meristems (Site not responding. Last check: 2007-10-18)
		The apical meristem is a group of cells that retain the ability to continue divisions, forming new cells continuously as the plant grows.
		Woody plants have SECONDARY growth, in that they have a special lateral meristem called the vascular cambium, that allows for growth in diameter.
		The cambium makes large cells early in the year, and smaller ones later in the summer, and this cycling of large and small cells is responsible for the appearance of growth rings in the wood, usually 1 "ring" per year.

		meristems are especially suitable for studies of stem cell biology.
		In this model of shoot meristem initiation, the first leaf primordia (green) arise before the central cells appear to be specified (red), whereas subsequent leaves are derived from the stem cells.
		Mutations affecting partitioning of the shoot meristem primordium could result in an altered size of the stem cell region, represented by stm (with fused organ primordia, arrow) and clv (with an increased meristem, arrow) mutants.
