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, 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.
Cryptantha is a genus of flowering plants in the borage family, Boraginaceae.They are known commonly as cat's eyes and popcorn flowers (the latter name is also used to refer to the closely related genus Plagiobothrys, [1] and members of the subtribe of Amsinckiinae). [2]
As the plant develops and throws off babies, or "pups", these may be optionally removed and propagated, either in a vessel of water for a time or directly planted into new substrate. Conversely, if the pups are allowed to remain connected to the mother plant and hang naturally, the appearance vaguely mimics spiders hanging by their silken ...
Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Viridiplantae, together with red algae and glaucophyte algae, form the supergroup Primoplantae, also known as Archaeplastida or Plantae sensu lato. The ancestral green alga was a unicellular flagellate. [20]
Depending on the species, Chlorophyceae can grow unicellular (e.g. Chlamydomonas), colonial (e.g. Volvox), coenocytic (e.g. Characiosiphon), or filamentous (e.g. Chaetophora). In their vegetative state, some members have flagella while others produce them only in reproductive stages; still others never produce flagella. [2]
Ulva lactuca is a thin flat green alga growing from a discoid holdfast. The margin is somewhat ruffled and often torn. The margin is somewhat ruffled and often torn. It may reach 18 centimetres (7 in) or more in length, though generally much less, and up to 30 cm (12 in) across. [ 3 ]
Both the "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis. [ 22 ] [ 23 ] The classification of Bryophyta is supported both by Puttick et al. 2018, [ 24 ] and by phylogenies involving the hornwort genomes that have also since been sequenced.
