Photosynthesis (/ ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1 ] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Foxgloves produce toxic chemicals including cardiac and steroidal glycosides, deterring herbivory. Plant defense against herbivory or host-plant resistance (HPR) is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites, known as ...
During his Italian journey, Goethe formulated a theory of plant metamorphosis in which the archetypal form of the plant is to be found in the leaf – he writes, "from top to bottom a plant is all leaf, united so inseparably with the future bud that one cannot be imagined without the other". [72] In 1790, he published his Metamorphosis of Plants.
Ocean thermal energy conversion (OTEC) is a renewable energy technology that harnesses the temperature difference between the warm surface waters of the ocean and the cold depths to run a heat engine to produce electricity. It is a unique form of clean energy generation that has the potential to provide a consistent and sustainable source of power.
No, they're not quadruplets. Each girl was born on the same day, exactly three years apart. That's right — Sophia, 9, Giuliana, 6, Mia, 3, and Valentina, 2.5 weeks old — have the exact same ...
Boar’s Head announced Friday it has indefinitely shut down a Virginia deli meat plant and discontinuing the liverwurst that is linked to a deadly multi-state listeria outbreak that also sickened ...
A rotary hydroponic garden is a style of commercial hydroponics created within a circular frame which rotates continuously during the entire growth cycle of whatever plant is being grown. While system specifics vary, systems typically rotate once per hour, giving a plant 24 full turns within the circle each 24-hour period.
A domain contains one or more kingdoms. Intermediate minor rankings are not shown. In biology, a kingdom is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla (singular phylum). Traditionally, some textbooks from the United States and Canada used a system of six kingdoms (Animalia ...
