Plant development. Important structures in plant development are buds, shoots, roots, leaves, and flowers; plants produce these tissues and structures throughout their life from meristems [ 1] located at the tips of organs, or between mature tissues. Thus, a living plant always has embryonic tissues. By contrast, an animal embryo will very ...

It is particularly decorative in winter; the best effect is achieved by coppicing it every two to three years to stimulate the production of longer ...
Auxin diffuses along the shaded side of the plant, and causes cellulose in the cell wall to break, allowing turgor (water pressure) to expand the cell. Growth of cells contributes to the plant's size, unevenly localized growth produces bending, turning and directionalization of organs- for example, stems turning toward light sources ...
Water sprouts or water shoots are shoots that arise from the trunk of a tree or from branches that are several years old, from latent buds. [1] The latent buds might be visible on the bark of the tree, or submerged under the bark as epicormic buds. They are sometimes called suckers, although that term is more correctly applied to shoots that ...
An epicormic shoot is a shoot growing from an epicormic bud, which lies underneath the bark of a trunk, stem, or branch of a plant . Epicormic buds lie dormant beneath the bark, their growth suppressed by hormones from active shoots higher up the plant. Under certain conditions, they grow into active shoots, such as when damage occurs to higher ...
