Plant
A plant is a living organism that belongs to the kingdom Plantae and is characterized by its ability to produce its own food through photosynthesis. Most plants are rooted in soil, have stems and leaves, and contain the green pigment chlorophyll, which captures sunlight to convert carbon dioxide and water into glucose and oxygen. This process not only sustains the plant itself but also supports life on Earth by generating oxygen and serving as the foundation of most food chains.
Plants come in a wide variety of forms, from tiny mosses and grasses to towering trees and flowering shrubs. They play critical roles in ecosystems by stabilizing soil, regulating water cycles, providing habitats, and storing carbon. Many plants also have reproductive structures such as flowers or cones and produce seeds that enable them to reproduce and spread.
In addition to their ecological importance, plants are essential to human life. They provide food, medicine, fiber, fuel, and raw materials for countless industries. Their beauty and diversity also contribute to cultural and aesthetic value around the world. Understanding and protecting plant life is key to preserving biodiversity and sustaining the health of the planet.

Sep. 4, 2026 Puerto Rico’s normally rainy season has instead brought a severe and fast-growing drought. By August 25, three-quarters of the territory was in at least moderate drought, with extreme drought covering 44 percent and some areas receiving less than ...
Sep. 4, 2026 A giant iceberg measuring more than 76 square kilometers broke from Greenland’s Petermann Glacier in August 2026, marking the Arctic’s largest glacier calving event since 2020. The berg later slammed into Joe Island but survived without breaking ...
Sep. 3, 2026 Morning glories may be getting caught in an evolutionary tug-of-war between surviving climate change and attracting increasingly scarce pollinators. Over just nine years, researchers found that the plants’ rate of adaptation plunged by 96%, even ...
Sep. 3, 2026 Elephant Butte Reservoir, New Mexico’s largest reservoir, plunged to just 1.4 percent capacity in July 2026 after years of extreme drought and record early snowmelt. The dramatic decline exposed long-submerged debris and underscored the growing ...
Sep. 1, 2026 Rare storms covered huge stretches of Chile’s Atacama Desert in snow and dumped extraordinary amounts of rain on one of the driest regions on Earth. The extreme weather shut down observatories, triggered damaging floods and mudflows, and unfolded ...
Aug. 30, 2026 Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near the marine edge of the Thwaites Glacier. Many appear to be glacial earthquakes caused when huge icebergs break off, capsize, and collide with ...
Aug. 30, 2026 Researchers have produced a form of Spirulina containing biologically active vitamin B12 at levels comparable to beef. By carefully controlling the light used to grow the algae, they overcame a major problem with conventional Spirulina, which mainly ...
Aug. 29, 2026 Researchers have discovered a way to turn notoriously difficult-to-recycle PVC plastic into a key ingredient used in high-performance lubricants such as engine oil. The technique could give mountains ...
Aug. 29, 2026 Researchers have discovered that Western Australia’s iron-rich rocks can naturally generate hydrogen and that the process may be boosted to produce much larger amounts. If it can be scaled up, the vast formations beneath the Pilbara could become a ...
Aug. 28, 2026 More than 1,000 volunteers buried cotton underwear across Switzerland to help scientists measure how active different soils are. The faster the fabric disappeared, the more biological activity was taking place underground. Gardens showed the fastest ...
Aug. 27, 2026 Beneath the rocky slopes of Mount Timpanogos lies far more ice than anyone walking across the surface might suspect. Researchers used gravity measurements to map the buried glacier in 3D and found it is about 83% ice, with enough frozen water to ...
Aug. 26, 2026 A Manhattan-sized ice island has broken away from Greenland’s Petermann Glacier after years of growing fractures weakened its floating ice tongue. Scientists expect two more huge sections could soon detach, potentially removing about 22 percent of ...
