A monophyletic group of green plants that includes all land plants (EMBRYOPHYTA) and all green algae (CHLOROPHYTA and STREPTOPHYTA).
The only living genus of the order Equisetales, class Equisetopsida (Sphenopsida), division Equisetophyta (Sphenophyta); distantly related to ferns. It grows in moist places. The hollow, jointed, ridged stems contain SILICATES.
A phylum of photosynthetic EUKARYOTA bearing double membrane-bound plastids containing chlorophyll a and b. They comprise the classical green algae, and represent over 7000 species that live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater.
The relationships of groups of organisms as reflected by their genetic makeup.
Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.
The process of cumulative change at the level of DNA; RNA; and PROTEINS, over successive generations.
A plant species, of the genus OENOTHERA, family ONAGRACEAE, that is the source of evening primrose oil.
A plant genus of the family ONAGRACEAE. Members contain oenotheins.
Higher plants that live primarily in terrestrial habitats, although some are secondarily aquatic. Most obtain their energy from PHOTOSYNTHESIS. They comprise the vascular and non-vascular plants.
A phylum of green plants comprising CHAROPHYCEAE (streptophyte green algae) and EMBRYOPHYTA (land plants).
A plant family of the order Polygalales, subclass Rosidae, class Magnoliopsida.
The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.
The above-ground plant without the roots.
A family of nucleocytoplasmic, large, double-stranded DNA viruses with extremely complex genomes.
A large family of narrow-leaved herbaceous grasses of the order Cyperales, subclass Commelinidae, class Liliopsida (monocotyledons). Food grains (EDIBLE GRAIN) come from members of this family. RHINITIS, ALLERGIC, SEASONAL can be induced by POLLEN of many of the grasses.
A plant genus of the family FABACEAE. Many species of this genus, including the medicinal C. senna and C. angustifolia, have been reclassified into the Senna genus (SENNA PLANT) and some to CHAMAECRISTA.
A plant genus of the family FABACEAE. Some species were reclassified from CASSIA and Senna.
Preparations of Cassia senna and C. angustifolia (see SENNA PLANT). They contain sennosides, which are anthraquinone type CATHARTICS and are used in many different preparations as laxatives.
A plant genus of the family FABACEAE. SENNA EXTRACT is obtained from members of this genus. Members contain ANTHRAQUINONES and have been an ingredient in laxatives (CATHARTICS). Many species of the CASSIA genus have been reclassified into this genus. This bush should not be confused with the Cassia tree (CINNAMOMUM).
Sound that expresses emotion through rhythm, melody, and harmony.
A plant species of the genus CINNAMOMUM that contains CINNAMATES and has been used in traditional Chinese medicine (DRUGS, CHINESE HERBAL).
The outer layer of the woody parts of plants.
A family of double-stranded DNA viruses containing one genus Asfivirus. It is the source of AFRICAN SWINE FEVER.
Viruses whose nucleic acid is DNA.
A family of DNA plant viruses that infect eukaryotic algae.
Usually refers to planned scientific data-gathering excursions.
The salinated water of OCEANS AND SEAS that provides habitat for marine organisms.
A body of water covering approximately one-fifth of the total ocean area of the earth, extending amidst Africa in the west, Australia in the east, Asia in the north, and Antarctica in the south. Including the Red Sea and the Persian Gulf, it constitutes the third largest ocean after the ATLANTIC OCEAN and the PACIFIC OCEAN. (New Encyclopaedia Britannica Micropaedia, 15th ed, 1990, p289)
