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]
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.
The emergent layer contains a small number of very large trees called emergents, which grow above the general canopy, reaching heights of 45–55 m, although on occasion a few species will grow to 70–80 m tall. [21] [22] They need to be able to withstand the hot temperatures and strong winds that occur above the canopy in some areas.
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.
The habitat of Paraceratherium appears to have varied across its range, based on the types of geological formations it has been found in. [30] The Hsanda Gol Formation of Mongolia represents an arid desert basin, and the environment is thought to have had few tall trees and limited brush cover, as the fauna consisted mainly of animals that fed ...
Chlorophyll is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. [2] Its name is derived from the Greek words χλωρός (khloros, "pale green") and φύλλον (phyllon, "leaf"). [3] Chlorophyll allows plants to absorb energy from light.
It is often found in the chloroplasts of C 4 plants, though it has also been found in some C 3 angiosperms, [23] and even some gymnosperms. [128] The chloroplast peripheral reticulum consists of a maze of membranous tubes and vesicles continuous with the inner chloroplast membrane that extends into the internal stromal fluid of the chloroplast.
