Aloe vera (/ ˈ æ l oʊ (i) v ɛr ə, v ɪər-/) [3] is a succulent plant species of the genus Aloe. [4] It is widely distributed, and is considered an invasive species in many world regions.
The discovery of the Casparian strip dates back to the mid-19th century, and advances in the understanding of the endodermis of plant roots. [15] In 1865, the German botanist Robert Caspary first described the endodermis of the root of plants, found that its cell wall was thickened, and named it Schuchtzscheide.
Mosses are examples of non-vascular plants.. Non-vascular plants are plants without a vascular system consisting of xylem and phloem.Instead, they may possess simpler tissues that have specialized functions for the internal transport of water.
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]A germination rate experiment. Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
The cuticle is composed of an insoluble cuticular membrane impregnated by and covered with soluble waxes. Cutin, a polyester polymer composed of inter-esterified omega hydroxy acids which are cross-linked by ester and epoxide bonds, is the best-known structural component of the cuticular membrane.
Alternanthera is a genus of flowering plants in the family Amaranthaceae.It is a widespread genus with most species occurring in the tropical Americas, [2] [3] and others in Asia, Africa, and Australia. [3]
Alocasia macrorrhizos is a species of flowering plant in the arum family that it is native to rainforests of Maritime Southeast Asia, New Guinea, and Queensland [1] and has long been cultivated in South Asia, the Philippines, many Pacific islands, and elsewhere in the tropics.
Roots are specialized for the uptake of water, nutrients (including ions for proper function). [12] Similar to the endodermis, the exodermis contains very compact cells and is surrounded by a Casparian band, two features which are used to restrict the flow of water to a symplastic fashion (through the cytoplasm) rather than apoplastic fashion which (through the cell wall) flow through passages ...
