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 ...
Life forms: (1) Phanerophyte, (2; 3) Chamaephyte, (4) Hemicryptophyte, (5; 6) Geophyte, (7) Helophyte, (8; 9) Hydrophyte. Therophyte and epiphyte are not shown. The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors.
The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced / ɑːr k ɪ ˈ p l æ s t ɪ d ə /) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes. [6]
Warming developed his life-form scheme further in his "On the life forms in the vegetable kingdom". [10] He presented a hierarchic scheme, first dividing plants into heterotrophic and autotrophic , the latter group then into aquatic and terrestrial , the land plants into muscoid , lichenoid , lianoid and all other autonomous land plants, which ...
The plant lives for many years until it flowers; estimates of its life span range from 5–15 years to 40 years. [ 5 ] [ 6 ] Flowering occurs mostly from mid-June to November. Atypical plants possess branches that flower and die independently from the main plant, so that these individuals die only after the last branch flowers.
Chlorophytum comosum, usually called spider plant or common spider plant due to its spider-like look, also known as spider ivy, airplane plant, [2] ribbon plant (a name it shares with Dracaena sanderiana), [3] and hen and chickens, [4] is a species of evergreen perennial flowering plant of the family Asparagaceae.
The distinctions between the genera are artificial, since they do not correspond with monophyletic groupings; [7] occasionally, Ankistrodesmus is found as single cells. [6] Other similar genera include Keratococcus and Elakatothrix. [3] Identification of species chiefly depends on details of the size and shape of cells. [2]
Most research has showed the maximum age to be about 9–10 years, with a few living past 11 years. The preferred temperature range for the yellow perch is 17 to 25 °C (63 to 77 °F), with an optimum range of 21 to 24 °C (70 to 75 °F) and a lethal limit in upwards of 33 °C (91 °F) and a stress limit over 26 °C (79 °F).
