plant : any of a kingdom (Plantae) of multicellular eukaryotic mostly photosynthetic organisms typically lacking locomotive movement or obvious nervous or sensory organs and possessing cellulose cell walls — Webster
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is today generally limited to the green plants, which form an unranked clade Viridiplantae (Latin for “green plants”). This includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae, and excludes the red and brown algae. Historically, plants formed one of two kingdoms covering all living things that were not animals, and both algae and fungi were treated as plants; however all current definitions of “plant” exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria).
Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although asexual reproduction is also common. — Wikipedia
Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including ca 369,000 species of flowering plants), and ca 20,000 are bryophytes. — Wikipedia

Botanical garden is a garden dedicated to the collection, cultivation and display of a wide range of plants labelled with their botanical names. It may contain specialist plant collections such as cacti and other succulent plants, herb gardens, plants from particular parts of the world, and so on; there may be greenhouses, shadehouses, again with special collections such as tropical plants, alpine plants, or other exotic plants. Visitor services at a botanical garden might include tours, educational displays, art exhibitions, book rooms, open-air theatrical and musical performances, and other entertainment.
Botanical gardens are often run by universities or other scientific research organizations, and often have associated herbaria and research programmes in plant taxonomy or some other aspect of botanical science. In principle, their role is to maintain documented collections of living plants for the purposes of scientific research, conservation, display, and education, although this will depend on the resources available and the special interests pursued at each particular garden. — Wikipedia

Grazing animals drove domestication of grain crops

Nature Plants, Published online: 08 July 2019; doi:10.1038/s41477-019-0470-4Herbacious grain annuals in the mid-Holocene period were typically so hard to forage and eat that their use by humans was seen as a ‘last resort’, but this Perspective argues that a switch from animal to human dispersal allowed for domestication into the crops that became the foundation for societies around the world.

Nature Plants, Published online: 08 July 2019; doi:10.1038/s41477-019-0468-yThe Early Cretaceous record of monocots is poor compared to other angiosperms. A well-preserved fossil monocot from the Crato plattenkalk limestone supports the possibility of an early radiation of monocots into the tropics of Northern Gondwana. […]

When tornadoes touch down, we brace for news of property damage, injuries, and loss of life, but the high-speed wind storms wreak environmental havoc, too. They can cut through massive swaths of forest, destroying trees and wildlife habitat, and opening up opportunities for invasive species to gain ground. […]

on July 17, 2019 at 12:43 pm
Bee populations are declining, and neonicotinoid pesticides continue to be investigated -- and in some cases banned -- because of their suspected role as a contributing factor. However, limitations in sampling and analytical techniques have prevented a full understanding of the connection. Now, researchers describe a new approach to sample neonicotinoids and other pesticides in plants, which could explain how bees are exposed to the substances. […]
Timing is everything for the mutualistic...
on July 16, 2019 at 9:41 pm
Ant-acacia plants attract ants by offering specialized food and hollow thorns in which the ants live, while the ant colony in turn defends its acacia against herbivores. This mutualistic relationship only occurs in older plants. New findings by plant biologists identify the genetic pathway that appears to regulate the timing of the acacia's ant-sustaining arsenal.

Carnivorous plants: No escape for mosquitoes
on July 9, 2019 at 11:44 am
Physically bound to a specific location, plants have to devise special ways to secure their supply of vital nutrients. Most plants have developed a root system to the nutrients they need in order to survive out of the soil. But what if nutrient-poor soils fail to provide the necessities of life? Carnivorous plants such as the Venus flytrap have found a way out of this dilemma. […]
