  2. Glycocalyx - Wikipedia

    en.wikipedia.org/wiki/Glycocalyx

    The glycocalyx (pl.: glycocalyces or glycocalyxes), also known as the pericellular matrix and cell coat, is a layer of glycoproteins and glycolipids which surround the cell membranes of bacteria, epithelial cells, and other cells. [1] Animal epithelial cells have a fuzz-like coating on the external surface of their plasma membranes.

  3. Slime layer - Wikipedia

    Capsules are more organized and difficult to remove compared to their slime layer counterparts. [5] Another highly organized, but separate structure is an S-layer . S-layers are structures that integrate themselves into the cell wall and are composed of glycoproteins, these layers can offer the cell rigidity and protection. [ 6 ]

  4. Algae - Wikipedia

    en.wikipedia.org/wiki/Algae

    The chloroplasts of red algae have chlorophylls a and c (often), and phycobilins, while those of green algae have chloroplasts with chlorophyll a and b without phycobilins. Land plants are pigmented similarly to green algae and probably developed from them, thus the Chlorophyta is a sister taxon to the plants; sometimes the Chlorophyta, the ...

  5. Brown algae - Wikipedia

    en.wikipedia.org/wiki/Brown_algae

    A number of Paleozoic fossils have been tentatively classified with the brown algae, although most have also been compared to known red algae species. Phascolophyllaphycus possesses numerous elongate, inflated blades attached to a stipe. It is the most abundant of algal fossils found in a collection made from Carboniferous strata in Illinois. [42]

    en.wikipedia.org/wiki/Protist

    A third lineage of algae, the glaucophytes (25 species), [62] contains rare and obscure species found in surfaces of freshwater and terrestrial habitats. [104] The red algae or Rhodophyta (>7,100 species) are a group of diverse morphologies, ranging from single cells to multicellular filaments to giant pseudoparenchymatous thalli, all

    en.wikipedia.org/wiki/Portal:Algae

    Algae constitute a polyphyletic group since they do not include a common ancestor, and although their chlorophyll-bearing plastids seem to have a single origin (from symbiogenesis with cyanobacteria), they were acquired in different ways. Green algae are a prominent examples of algae that have primary chloroplasts derived from endosymbiont ...

  9. Chara (alga) - Wikipedia

    en.wikipedia.org/wiki/Chara_(alga)

    Chara is a genus of charophyte green algae in the family Characeae. They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures. They are found in freshwater, particularly in limestone areas throughout the northern temperate zone, where they grow submerged, attached to the muddy bottom.
