Green growth is a concept in economic theory and policymaking used to describe paths of economic growth that are environmentally sustainable. [1][2] It is based on the understanding that as long as economic growth remains a predominant goal, a decoupling of economic growth from resource use and adverse environmental impacts is required. As such ...
Thigmotropism. Redvine (Brunnichia ovata) tendrils coil upon contact. In plant biology, thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants ...
Zygnematophyceae. Cladistically included but traditionally excluded taxa. Embryophyta. Charophyta (UK: / kəˈrɒfɪtə, ˌkærəˈfaɪtə /) is a group of freshwater green algae, called charophytes (/ ˈkærəˌfaɪts /), sometimes treated as a division, [2] yet also as a superdivision [3] or an unranked clade.
The green world hypothesis proposes that predators are the primary regulators of ecosystems: they are the reason the world is 'green', by regulating the herbivores that would otherwise consume all the greenery. [1][2] It is also known as the HSS hypothesis, after Hairston, Smith and Slobodkin, the authors of the seminal paper on the subject. [3]
Life history theory (LHT) is an analytical framework [1] designed to study the diversity of life history strategies used by different organisms throughout the world, as well as the causes and results of the variation in their life cycles. [2] It is a theory of biological evolution that seeks to explain aspects of organisms' anatomy and behavior ...
Prochlorococcus, an influential marine cyanobacterium which produces much of the world's oxygen. Cyanobacteria are globally widespread photosynthetic prokaryotes and are major contributors to global biogeochemical cycles. [ 25 ] They are the only oxygenic photosynthetic prokaryotes, and prosper in diverse and extreme habitats. [ 26 ]
Reproduction completes and perpetuates the cycle. In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then ...
Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Viridiplantae, together with red algae and glaucophyte algae, form the supergroup Primoplantae, also known as Archaeplastida or Plantae sensu lato. The ancestral green alga was a unicellular flagellate.
