They have extremely long roots to seek water from very far under ground. As a legume, mesquites are one of the few sources of fixed nitrogen in the desert habitat. The trees bloom from spring to summer. They often produce fruits known as "pods".
Auxin moves toward higher concentrations on the bottom side of the root and suppresses elongation. The asymmetric distribution of auxin leads to differential growth of the root tissues, causing the root to curve and follow the gravity stimuli. Statoliths are also found in the endodermic layer of the hypocotyl, stem, and inflorescence stock. The ...
Buttress roots, also known as plank roots, are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They may prevent the tree from falling over (hence the name buttress ).
The roots of a tree serve to anchor it to the ground and gather water and nutrients to transfer to all parts of the tree. They are also used for reproduction, defence, survival, energy storage and many other purposes. The radicle or embryonic root is the first part of a seedling to emerge from the seed during the process of germination.
Aerial roots are roots growing above the ground. They are often adventitious , i.e. formed from nonroot tissue. They are found in diverse plant species, including epiphytes such as orchids ( Orchidaceae ), tropical coastal swamp trees such as mangroves , banyan figs ( Ficus subg.
The unique ecosystem found in the intricate mesh of mangrove roots offers a quiet marine habitat for young organisms. [30] In areas where roots are permanently submerged, the organisms they host include algae , barnacles , oysters , sponges , and bryozoa , which all require a hard surface for anchoring while they filter-feed.

Carya aquatica, the bitter pecan or water hickory, is a large tree, that can grow over 30 metres (98 ft) tall of the Juglandaceae or walnut family. In the American South it is a dominant plant species found on clay flats and backwater areas near streams and rivers. The species reproduces aggressively both by seed and sprouts from roots and from ...
