Grapevine tendrils and leaves. Thorns. Cladodes. Aerial stem modifications are modifications to the aerial stems, [1] vegetative buds and floral buds of plants growing in different conditions and which perform functions such as climbing, protection, support, synthesis of food, or vegetative propagation.
Subaerial stems are the stems that do not rise up but grow just above the ground. As a type of asexual propagation, these subaerial stolons, also called runners, often develop roots and leaves from their nodes. [7] Some pond plants have subaerial leaves as well as submerged leaves (water plantain, flowering rush). [8]
The California Institute of Technology, long a bastion of male STEM students, enrolls an undergraduate class of majority women this fall, the first time in its 133-year history.
In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots ...
Underground stems are modified plant parts that derive from stem tissue but exist under the soil surface. [1] They function as storage tissues for food and nutrients, facilitate the propagation of new clones, and aid in perennation (survival from one growing season to the next). [ 2 ]
In geology, a subaerial unconformity is a surface that displays signs of erosion by processes that commonly occur on the surface. [1] These processes generating the subaerial unconformity can include wind degradation, pedogenesis, dissolution processes such as karstification as well as fluvial processes such as fluvial erosion, bypass and river rejuvenation.
The Technology Student Association (TSA) is a national non-profit career and technical student organization (CTSO) of over 300,000 middle and high school student members engaged in science, technology, engineering, and mathematics (STEM). TSA's mission is to enhance personal development, leadership, and career opportunities in STEM, whereby ...
Mathematics, Engineering, Science Achievement (MESA) is an academic preparation program for pre-college, community college and university-level students.Established in 1970 in California, the program provides academic support to students from educationally disadvantaged backgrounds throughout the education pathway so they will excel in math and science and ultimately attain four-year degrees ...
