  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. 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]

  4. Thallus - Wikipedia

    en.wikipedia.org/wiki/Thallus

    Although a thallus is largely undifferentiated in terms of its anatomy, there can be visible differences and functional differences. A kelp, for example, may have its thallus divided into three regions. The parts of a kelp thallus include the holdfast (anchor), stipe (supports the blades) and the blades (for photosynthesis). [2]

  5. 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 algae. 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 ...

  6. Diatom - Wikipedia

    en.wikipedia.org/wiki/Diatom

    Heterokont chloroplasts appear to derive from those of red algae, rather than directly from prokaryotes as occurred in plants. This suggests they had a more recent origin than many other algae. However, fossil evidence is scant, and only with the evolution of the diatoms themselves do the heterokonts make a serious impression on the fossil record.

  7. Lichen anatomy and physiology - Wikipedia

    en.wikipedia.org/wiki/Lichen_anatomy_and_physiology

    Lichen anatomy and physiology is very different from the anatomy and physiology of the fungus and/or algae and/or cyanobacteria that make up the lichen when growing apart from the lichen, either naturally, or in culture. The fungal partner is called the mycobiont. The photosynthetic partner, algae or cyanobacteria, is called the photobiont.

  8. 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

  9. Valonia ventricosa - Wikipedia

    en.wikipedia.org/wiki/Valonia_ventricosa

    Valonia ventricosa, also known as bubble algae, sea grape, [2] or sailor's eyeballs, [3] is a species of algae found in oceans throughout the world in tropical and subtropical regions, within the phylum Chlorophyta. It is one of the largest known unicellular organisms. [3] [4] Valonia ventricosa in the Red Sea
