Accessory bud – an embryonic shoot occurring above or to the side of an axillary bud; also known as supernumerary bud. Adventitious bud – a bud that arises at a point on the plant other than at the stem apex or a leaf axil. Axillary – an embryonic shoot which lies at the junction of the stem and petiole of a plant. Dormant – see "Latent ...
Arranged on a conical surface (like a snail shell); used to describe inflorescence s in which the bud s are arranged in an almost helical manner on the outside of a long, tapering, conical rachis. bract A modified leaf associated with a flower or inflorescence and differing in shape, size, or color from other leaves (and without an axillary bud ...
Stoma in a tomato leaf shown via colorized scanning electron microscope image A stoma in horizontal cross section The underside of a leaf. In this species (Tradescantia zebrina) the guard cells of the stomata are green because they contain chlorophyll while the epidermal cells are chlorophyll-free and contain red pigments.
European beech (Fagus sylvatica) bud. In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem.Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately.
The mouth is developed partly from the stomodeum, and partly from the floor of the anterior portion of the fore-gut.. By the growth of the head end of the embryo, and the formation of the cephalic flexure, the pericardial area and the buccopharyngeal membrane come to lie on the ventral surface of the embryo.
Recaulescences is the fusion of the subtending leaf with the stem holding the bud or the bud itself, [7] thus the leaf or bract is adnate to the stem of flower. When the formation of the bud is shifted up the stem distinctly above the subtending leaf, it is described as concaulescent.
Bud: An embryonic shoot with immature stem tip. Bulb : A short vertical underground stem with fleshy storage leaves attached, e.g. onion , daffodil , and tulip . Bulbs often function in reproduction by splitting to form new bulbs or producing small new bulbs termed bulblets.
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
