  2. Chlorophyta - Wikipedia

    en.wikipedia.org/wiki/Chlorophyta

    Simplified diagram of a chlorophyte cell combining structures seen across the phylum: 1) flagellum; 2) synistosome with fibers adhering to a pair of basal bodies; 3) basal body; 4) microtubular rootlet belonging to the "X-2-X-2" arrangement, in this case 4-2-4-2 (only front-facing rootlets are shown); 5) flagellar pit (only two of four flagella ...

  3. Volvox carteri - Wikipedia

    en.wikipedia.org/wiki/Volvox_carteri

    Volvox carteri [1] is a species of colonial green algae in the order Volvocales. [2] The V. carteri life cycle includes a sexual phase and an asexual phase.V. carteri forms small spherical colonies, or coenobia, of 2000–6000 Chlamydomonas-type somatic cells and 12–16 large, potentially immortal reproductive cells called gonidia.

  4. Chlorophyceae - Wikipedia

    en.wikipedia.org/wiki/Chlorophyceae

    Their body plans are diverse and range from single flagellated or non-flagellated cells to colonies or filaments of cells. [2] The class Chlorophyceae has been distinguished on the basis of ultrastructural morphology; [ 3 ] molecular traits are also being used to classify taxa within the class.

  5. Volvox - Wikipedia

    en.wikipedia.org/wiki/Volvox

    Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. Volvox species form spherical colonies of up to 50,000 cells, and for this reason they are sometimes called globe algae.

  6. Raunkiær plant life-form - Wikipedia

    en.wikipedia.org/wiki/Raunkiær_plant_life-form

    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.

  7. Viridiplantae - Wikipedia

    en.wikipedia.org/wiki/Viridiplantae

    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.

  8. Archaeplastida - Wikipedia

    en.wikipedia.org/wiki/Archaeplastida

    Both the "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis. [ 39 ] [ 40 ] The classification of Bryophyta is supported both by Puttick et al. 2018, [ 41 ] and by phylogenies involving the hornwort genomes that have also since been sequenced.

  9. Chlamydomonadales - Wikipedia

    en.wikipedia.org/wiki/Chlamydomonadales

    Volvocine algae range from the unicellular Chlamydomonas to the multicellular Volvox through various intermediate forms and are used as a model for research into the evolution of multicellularity. The spheroidal colony is thought to have evolved twice independently within this group: once in the Volvocaceae, from Pandorina to Volvox, and the ...
