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. [citation needed] Non-vascular plants include two distantly related groups: treat as three separate land-plant divisions, namely: Bryophyta ...
Phosphorus cycle. The phosphorus cycle is the biogeochemical cycle that involves the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based materials do not enter ...
Pinus merkusii is a medium-sized to large tree, reaching 25–45 metres (82–148 feet) tall and with a trunk diameter of up to 1 m (3 ft 3 in). The bark is orange-red, thick and deeply fissured at the base of the trunk, and thin and flaky in the upper crown. The leaves ('needles') are in pairs, very slender, 15–20 centimetres (6–8 inches ...
Aloe vera ( / ˈæloʊ ( i) vɛrə, vɪər -/) [ 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. [ 4][ 5] An evergreen perennial, it originates from the Arabian Peninsula, but also grows wild in tropical, semi-tropical, and arid climates around the ...
Botanists define vascular plants by three primary characteristics: Vascular plants have vascular tissues which distribute resources through the plant. Two kinds of vascular tissue occur in plants: xylem and phloem. Phloem and xylem are closely associated with one another and are typically located immediately adjacent to each other in the plant.
A more well-known xerophyte is the succulent plant Agave americana. It is cultivated as an ornamental plant popular across the globe. Agave nectar is garnered from the plant and is consumed as a substitute for sugar or honey. In Mexico, the plant's sap is usually fermented to produce an alcoholic beverage.
Perennial. In botany, a perennial plant or simply perennial is a plant that lives more than two years. [ 1][failed verification] The term ( per- + -ennial, "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth ...
Casparian strip. The Casparian strip is a band-like thickening in the center of the root endodermis (radial and tangential walls of endodermal cells) of vascular plants ( Pteridophytes [ 1] and Spermatophytes ). The composition of the region is mainly suberin, lignin and some structural proteins, which are capable of reducing the diffusive ...
