Plant–animal interaction. Plant-animal interactions are important pathways for the transfer of energy within ecosystems, where both advantageous and unfavorable interactions support ecosystem health. [ 1][ 2] Plant-animal interactions can take on important ecological functions and manifest in a variety of combinations of favorable and ...
Linnaeus's Systema Naturae lists only about 10,000 species of organisms, of which about 6,000 are plants and 4,236 are animals. [9] According to the historian of botany William T. Stearn , "Even in 1753 he believed that the number of species of plants in the whole world would hardly reach 10,000; in his whole career he named about 7,700 species ...
Animals in the water column are almost entirely dependent on primary production from living phytoplankton, while animals on the ocean floor always or sometimes feed on detritus. [34] Coccolithophorids and mollusks (including ammonites , rudists , freshwater snails , and mussels ), and those organisms whose food chain included these shell ...
Rainforests are forests characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described.
Carl Linnaeus[ a] (23 May 1707 [ note 1] – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné, [ 3][ b] was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy ". [ 4] Many of his writings were in Latin; his name is ...
The English word "tissue" derives from the French word "tissu", the past participle of the verb tisser, "to weave". The study of tissues is known as histology or, in connection with disease, as histopathology. Xavier Bichat is considered as the "Father of Histology". Plant histology is studied in both plant anatomy and physiology.
Nucleolus. The nucleolus ( / njuːˈkliːələs, ˌnjuːkliˈoʊləs /; pl.: nucleoli /- laɪ /) is the largest structure in the nucleus of eukaryotic cells. [ 1] It is best known as the site of ribosome biogenesis, which is the synthesis of ribosomes. The nucleolus also participates in the formation of signal recognition particles and plays a ...
The plants and animals that live in grasslands are connected through an unlimited web of interactions. But the removal of key species—such as buffalo and prairie dogs within the American West—and introduction of invasive species , like cane toads in northern Australia, have disrupted the balance in these ecosystems and damaged a number of ...
