Plant anatomy or phytotomy is the general term for the study of the internal structure of plants. Originally, it included plant morphology , the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Internode: An interval between two successive nodes. It possesses the ability to elongate, either from its base or from its extremity depending on the species. Node: A point of attachment of a leaf or a twig on the stem in seed plants. A node is a very small growth zone.
A stalk-like structure, internode located between the calyx and the other parts of the flower. anticlinal Pointing up, away from, or perpendicular to a surface. Contrast periclinal. antrorse Directed forward or upward, e.g. of hairs on a stem. Contrast retrorse. apetalous Lacking petal s. apex. pl. apices. The tip; the point furthest from the ...
The point of insertion, on the stem, of leaves or buds is a node, and the space between two successive nodes, an internode. The leaves , which emerge from the shoot, are specialised structures that carry out photosynthesis, and gas ( oxygen and carbon dioxide ) and water exchange.
Angiosperms The receptacle (grey) in relation to the ovary (red) in three types of flowers: hypogynous (I), perigynous (II), and epigynous (III). In angiosperms, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow.
Botany, also called plant science or phytology, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. [1] A botanist, plant scientist or phytologist is a scientist who specialises in this field.
Internode may refer to: Internode (botany), a portion of a plant stem between nodes; Internode (ISP), an Internet service provider in Australia;
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.
