Thirdly, plant morphology studies plant structure at a range of scales. At the smallest scales are ultrastructure, the general structural features of cells visible only with the aid of an electron microscope, and cytology, the study of cells using optical microscopy. At this scale, plant morphology overlaps with plant anatomy as a
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...

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 bud". Epicormic – vegetative buds that lie dormant beneath the bark, shooting after crown disturbance [14] Flower bud –
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage , as in "autumn foliage", [ 2 ] [ 3 ] while the leaves, stem, flower , and fruit collectively form the shoot system. [ 4 ]
Once the embryo germinates from its seed or parent plant, it begins to produce additional organs (leaves, stems, and roots) through the process of organogenesis. New roots grow from root meristems located at the tip of the root, and new stems and leaves grow from shoot meristems located at the tip of the shoot. [8]
The sterile leaves are modified leaves whose function is to protect the fertile parts or to attract pollinators. [1] The branch of the flower that joins the floral parts to the stem is a shaft called the pedicel, which normally dilates at the top to form the receptacle in which the various floral parts are inserted.
The functions of a plant's growing tips – its apical (or primary) meristems – include: lengthening through cell division and elongation; organising the development of leaves along the stem; creating platforms for the eventual development of branches along the stem; [4] laying the groundwork for organ formation by providing a stock of ...
