Chlorophytes are eukaryotic organisms composed of cells with a variety of coverings or walls, and usually a single green chloroplast in each cell. [4] They are structurally diverse: most groups of chlorophytes are unicellular, such as the earliest-diverging prasinophytes, but in two major classes (Chlorophyceae and Ulvophyceae) there is an evolutionary trend toward various types of complex ...
Chlorophytum (/ ˌ k l ɒr ə ˈ f aɪ t əm, ˌ k l ɔː-,-r oʊ-/, [3] [4]), sometimes colloquially referred to as the spider plants, is a genus of almost 200 species of evergreen perennial flowering plants in the century plant subfamily within the asparagus family. [5]
Researchers ventured into a nature reserve in Yunnan province as part of a wildlife survey in 2023, according to a study published Jan. 27 in the peer-reviewed journal Animals.
The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna (typically defined as animal species having body masses over 44 kilograms (97 lb)), [1] which resulted in a collapse in faunal density and diversity across the globe. [2]
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
Chlorophytum comosum grows to about 60 cm (24 in) tall, although as a hanging plant it can descend many feet. It has fleshy, tuberous roots, each about 5–10 cm (2–4 in) long. The long narrow leaves reach a length of 20–45 cm (8–18 in) and are around 6–25 millimetres (0.2–1.0 in) wide. [7] Flower of 'Vittatum'
The Meghalayan begins 4,200 years BP (c. 2251 BCE or 7750 HE). [6] [7] [8] Helama & Oinonen (2019) dated the start of the Meghalayan to 2190–1990 BCE. [9]The age began with a 200-year drought that impacted human civilizations in the Eastern Mediterranean, Mesopotamia, the Indus Valley and the Yangtze River Valley. [6] "
Corroborating this, a basal phagotroph Archaeplastida group has been found in the Rhodelphydia. [16] In some classification systems, the group has been treated as a kingdom, [17] under various names, e.g. Viridiplantae, Chlorobionta, or simply Plantae, the latter expanding the traditional plant kingdom of embryophytes to include the green algae.
