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]
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 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.
This video clip shows a visualization of the three-dimensional structure of the Pillars of Creation. Closer view of one pillar. Pillars of Creation is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle Nebula, in the Serpens constellation, some 6,500–7,000 light-years (2,000–2,100 pc; 61–66 Em) from Earth.

At 8 kilometres (5 mi) across, and estimated at 100,000 years old, [3] it may be one of the largest and oldest clonal colonies on Earth. [4] [5] [6] Among animals, the largest species are all marine mammals, specifically whales. The blue whale is believed to be the largest animal to have ever lived. [7]
Tardigrades live over the entire world, including the high Himalayas. [4] Tardigrades are also able to survive temperatures of close to absolute zero (−273 °C or −459 °F), [5] temperatures as high as 151 °C (304 °F), radiation that would kill other animals, [6] and almost a decade without water. [7]
Along the Norwegian coast these forests cover 5,800 km 2, [29] and they support large numbers of animals. [ 30 ] [ 31 ] Numerous sessile animals (sponges, bryozoans and ascidians) are found on kelp stipes and mobile invertebrate fauna are found in high densities on epiphytic algae on the kelp stipes and on kelp holdfasts.

The classification of living things into animals and plants is an ancient one. Aristotle (384–322 BC) classified animal species in his History of Animals, while his pupil Theophrastus (c. 371 –c. 287 BC) wrote a parallel work, the Historia Plantarum, on plants. [7]
