  2. Green algae - Wikipedia

    en.wikipedia.org/wiki/Green_algae

    Green algae are a group of photosynthetic, eukaryotic organisms that include species with haplobiontic and diplobiontic life cycles. The diplobiontic species, such as Ulva , follow a reproductive cycle called alternation of generations in which two multicellular forms, haploid and diploid, alternate, and these may or may not be isomorphic ...

  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. Ulvophyceae - Wikipedia

    en.wikipedia.org/wiki/Ulvophyceae

    The Ulvophyceae or ulvophytes are a class of green algae, [3] distinguished mainly on the basis of ultrastructural morphology, life cycle and molecular phylogenetic data. [4] The sea lettuce, Ulva, belongs here. Other well-known members include Caulerpa, Codium, Acetabularia, Cladophora, Trentepohlia and Monostroma.

  5. Alternation of generations - Wikipedia

    en.wikipedia.org/wiki/Alternation_of_generations

    The term "plants" is taken here to mean the Archaeplastida, i.e. the glaucophytes, red and green algae and land plants. Alternation of generations occurs in almost all multicellular red and green algae, both freshwater forms (such as Cladophora) and seaweeds (such as Ulva). In most, the generations are homomorphic (isomorphic) and free-living.

  6. Pediastrum - Wikipedia

    en.wikipedia.org/wiki/Pediastrum

    Pediastrum possesses a haplontic life cycle, and can be divided into three types. [12] The most commonly seen is the first kind of asexual life cycle (ALC1), which generates autocolonies. In ALC1 the zoospores aggregate into an orderly flat disk, with concentric rings (central cell, six cells, and then nine cells.)

  7. 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. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700.

  8. Bryopsis - Wikipedia

    en.wikipedia.org/wiki/Bryopsis

    The life history patterns of Bryopsis are highly variable, potentially the most diverse among any genus of green algae. [12] Bryopsis have highly variable life history patterns, even within species. The life cycle of Bryopsis has two stages alternating between an erect macroscopic stage which form macrothalli and a small branched phase which ...

  9. Algae - Wikipedia

    en.wikipedia.org/wiki/Algae

    The endosymbiotic green algae may have been acquired through myzocytosis rather than phagocytosis. [23] (Another group with green algae endosymbionts is the dinoflagellate genus Lepidodinium, which has replaced its original endosymbiont of red algal origin with one of green algal origin. A nucleomorph is present, and the host genome still have ...
