Water beads on the waxy cuticle of kale leaves. A plant cuticle is a protecting film covering the outermost skin layer of leaves, young shoots and other aerial plant organs (aerial here meaning all plant parts not embedded in soil or other substrate) that have no periderm. The film consists of lipid and hydrocarbon polymers infused with wax ...
The epicuticular wax produced by Dudleya brittonii has the highest ultraviolet light (UV) reflectivity of any known naturally occurring biological substance. Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs.
Storage pattern is a root axis swollen near the apical portion, thus forming a bulbous or tuberous structure at or near the root tip. It is commonly seen associated with a rhizomatous stem. It is seen in Costus speciosus , [ 12 ] Curcuma amada , [ 12 ] [ 13 ] Curcuma domestica , Asparagus sprengeri , Arrowroot ( Maranta ), etc. [ 13 ] and some ...
leaf tip: Ending abruptly in a small sharp point as a continuation of the midrib [4] multifid: multi + findere: whole leaf: Cleft into many parts or lobes obcordate: obcordatus: whole leaf: Heart-shaped, stem attaches at the tapering end oblanceolate: oblanceolatus: whole leaf: Much longer than wide and with the widest portion near the tip ...
1. A space between the threads of a net, e.g. that part of a leaf surface defined by each of the elements of a vein network; as with cacti, the area between the veinlets of a leaf. 2. A structure on the stem node of a cactus, morphologically a specialised branch; the region of a cactus upon which spine s, glochid s, and flowers are borne. aril
Some plants can store water in their root structures, trunk structures, stems, and leaves. Water storage in swollen parts of the plant is known as succulence. A swollen trunk or root at the ground level of a plant is called a caudex and plants with swollen bases are called caudiciforms .

When structures in different species are believed to exist and develop as a result of common, inherited genetic pathways, those structures are termed homologous. For example, the leaves of pine, oak, and cabbage all look very different, but share certain basic structures and arrangement of parts. The homology of leaves is an easy conclusion to ...
