Wood anatomy is a scientific sub-area of wood science, [1] which examines the variations in xylem anatomical characteristics across trees, shrubs, and herbaceous species to explore inquiries related to plant function, growth, and the environment. [2] [3]
Plant development is the process by which structures originate and mature as a plant grows. It is a subject studies in plant anatomy and plant physiology as well as plant morphology. The process of development in plants is fundamentally different from that seen in vertebrate animals. When an animal embryo begins to develop, it will very early ...
These cones, especially the woody female cones, are considered the "archetypal" tree cones. The female cone has two types of scale: bract scale and seed scale (or ovuliferous scale), one subtended by each bract scale, derived from a highly modified branchlet. On the upper-side base of each seed scale are two ovules that develop into seeds after ...
Young stars resembling a Christmas tree aglow with lights and a sparkling snow globe take center stage in new images from NASA’s space telescopes.
Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe. [2] [3] Many of these terms date back to the earliest herbalists and botanists, including Theophrastus.
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.
In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.
