Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Mangifera indica, commonly known as mango, is an evergreen [3] species of flowering plant in the family Anacardiaceae. [4] It is a large fruit tree, capable of growing to a height and width of 30 m (100 ft). [5] There are two distinct genetic populations in modern mangoes – the "Indian type" and the "Southeast Asian type". [6]
Mangiferin was first isolated from the leaves and bark of Mangifera indica (the mango tree). [1] It can also be extracted from mango peels and kernels, [2] [3] Iris unguicularis, [4] Anemarrhena asphodeloides rhizomes [5] and Bombax ceiba leaves. [6] It is also found in the genera Salacia and Cyclopia, as well as in coffee leaves and some ...
The genus Pistacia has sometimes been separated into its own family, the Pistaciaceae, based on the reduced flower structure, differences in pollen, and the feathery style of the flowers. [3] The nature of its ovary, though, does suggest it belongs in the Anacardiaceae, a position supported by morphological and molecular studies, and recent ...
A true root system consists of a primary root and secondary roots (or lateral roots). the diffuse root system: the primary root is not dominant; the whole root system is fibrous and branches in all directions. Most common in monocots. The main function of the fibrous root is to anchor the plant.
Most trees begin life with a taproot, [3] but after one to a few years the main root system changes to a wide-spreading fibrous root system with mainly horizontal-growing surface roots and only a few vertical, deep-anchoring roots. A typical mature tree 30–50 m tall has a root system that extends horizontally in all directions as far as the ...
As stems and roots mature lenticel development continues in the new periderm (for example, periderm that forms at the bottom of cracks in the bark). [citation needed] Lenticels are found as raised circular, oval, or elongated areas on stems and roots. In woody plants, lenticels commonly appear as rough, cork-like structures on young branches.
The seasonal variation in growth from the vascular cambium is what creates yearly tree rings in temperate climates. Tree rings are the basis of dendrochronology, which dates wooden objects and associated artifacts. Dendroclimatology is the use of tree rings as a record of past climates. The aerial stem of an adult tree is called a trunk.
