Topics related to "cambium"

cambium
cambium , thin layer of generative tissue lying between the bark and the wood of a stem, most active in woody plants. The cambium produces new layers of phloem on the outside and of xylem ( wood ) on the inside, thus increasing the diameter of the stem . In herbaceous plants the cambium is almost i... Read more
meristem
meristem , a specialized section of plant tissue characterized by cell division and growth. Much of the mature plant's growth is provided by meristems. Apical meristems found at the tips of stems and roots increase the length of these sections. Stems and roots may also grow in thickness or in diamet... Read more
bark
bark outer covering of the stem of woody plants, composed of waterproof cork cells protecting a layer of food-conducting tissue—the phloem or inner bark (also called bast). As the woody stem increases in size (see cambium ), the outer bark of inelastic dead cork cells gives way in patterns c... Read more
cork
cork protective, waterproof outer covering of the stems and roots of woody plants. Cork is a specialized secondary tissue produced by the cork cambium of the plant (see meristem , bark ). The regularly arranged walls of cork cells are impregnated with a waxy material, called suberin, that is almo... Read more
herbaceous plant
herbaceous plant , plant whose stem is soft and green and shows little growth of wood. The term is used to distinguish such plants from woody plants. Herbaceous plants, or herbs, as they are commonly called, may be annual —that is, the plants die after a year's growth, and the plants are pr... Read more
stem
stem supporting structure of a plant, serving also to conduct and to store food materials. The stems of herbaceous and of woody plants differ: those of herbaceous plants are usually green and pliant and are covered by a thin epidermis instead of by the bark of woody plants. There is relatively more... Read more
xylem
xylem A tissue that transports water and dissolved mineral nutrients in vascular plants. In flowering plants it consists of hollow vessels that are formed from cells (vessel elements) joined end to end. The end walls of the vessel elements are perforated to allow the passage of water. In less advanc... Read more
grafting
grafting horticultural practice of uniting parts of two plants so that they grow as one. The scion, or cion, the part grafted onto the stock or rooted part, may be a single bud, as in budding , or a cutting that has several buds. The stock may be a whole mature plant, such as an apple tree, or i... Read more
tissue
tissue in biology, aggregation of cells that are similar in form and function and the intercellular substances produced by them. The fundamental tissues in animals are epithelial, nerve, connective, and muscle tissue; blood and lymph are commonly classed separately as vascular tissue. In the higher... Read more
woodpecker
woodpecker common name for members of the Picidae, a large family of climbing birds found in most parts of the world. Woodpeckers typically have sharp, chisellike bills for pecking holes in tree trunks, and long, barbed, extensible tongues with which they impale their insect prey. Their spiny tail ... Read more
