While branches can be nearly horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings; they are natural examples of fractal patterns in nature, and, as observed by Leonardo da Vinci , their cross-sectional areas closely follow the da Vinci ...
All the branches of a tree at every stage of its height when put together are equal in thickness to the trunk [below them]. [ 39 ] A more general version states that when a parent branch splits into two or more child branches, the surface areas of the child branches add up to that of the parent branch. [ 40 ]
Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world. Trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses. In much of the world, forests are shrinking as trees ...
Botany is a natural science concerned with the study of plants.The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for ...

Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
"Our tree (on the 50th Street beach) is a true celebration of nature," Lisa Walsh of the OCNJ Queens wrote in an email, "adorned with handmade ornaments crafted from bird seed, peanut butter ...
Leopards are great climbers and can carry their kills up trees to keep them out of reach from scavengers and other predators. Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are ...
