  2. Algae - Wikipedia

    en.wikipedia.org/wiki/Algae

    A type of algae, Ancylonema nordenskioeldii, was found in Greenland in areas known as the 'Dark Zone', which caused an increase in the rate of melting ice sheet. [89] The same algae was found in the Italian Alps, after pink ice appeared on parts of the Presena glacier. [90] The various sorts of algae play significant roles in aquatic ecology.

  3. Marine protists - Wikipedia

    en.wikipedia.org/wiki/Marine_protists

    Some modern authors prefer to exclude multicellular organisms from the traditional definition of a protist, restricting protists to unicellular organisms. [9] [10] This more constrained definition excludes all brown, the multicellular red and green algae, and, sometimes, slime molds (slime molds excluded when multicellularity is defined as ...

  4. Brown algae - Wikipedia

    en.wikipedia.org/wiki/Brown_algae

    Although not all brown algae are structurally complex, those that are typically possess one or more characteristic parts. A holdfast is a rootlike structure present at the base of the alga. Like a root system in plants, a holdfast serves to anchor the alga in place on the substrate where it grows, and thus prevents the alga from being carried ...

  5. Phycology - Wikipedia

    en.wikipedia.org/wiki/Phycology

    Phycology (from Ancient Greek φῦκος (phûkos) 'seaweed' and -λογία 'study of') is the scientific study of algae. Also known as algology, phycology is a branch of life science. Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms

  6. Seaweed - Wikipedia

    en.wikipedia.org/wiki/Seaweed

    "Seaweed" lacks a formal definition, but seaweed generally lives in the ocean and is visible to the naked eye. The term refers to both flowering plants submerged in the ocean, like eelgrass, as well as larger marine algae. Generally, it is one of several groups of multicellular algae; red, green and brown. [7]

  7. Dinoflagellate - Wikipedia

    en.wikipedia.org/wiki/Dinoflagellate

    Botanists treated them as a division of algae, named Pyrrophyta or Pyrrhophyta ("fire algae"; Greek pyrr(h)os, fire) after the bioluminescent forms, or Dinophyta. At various times, the cryptomonads, ebriids, and ellobiopsids have been included here, but only the last are now considered close relatives. Dinoflagellates have a known ability to ...

  8. Marine primary production - Wikipedia

    en.wikipedia.org/wiki/Marine_primary_production

    Green algae and plants possess two forms of this pigment: chlorophyll a and chlorophyll b. Kelps, diatoms, and other photosynthetic heterokonts contain chlorophyll c instead of b, while red algae possess only chlorophyll a. All chlorophylls serve as the primary means plants use to intercept light in order to fuel photosynthesis.

  9. Chlamydomonas - Wikipedia

    en.wikipedia.org/wiki/Chlamydomonas

    Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -⁠də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]
