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.
Brown algae have many unique characteristics in terms of their metabolism and cell biology. Ergo, brown algae and in particular, E. siliculosus, are often used for explorative research. Its genome was the first brown macroalgal genome to be sequenced, with the expectation that E. siliculosus will serve as a genetic and genomic model for brown ...
The green algae and land plants have lost that pigment. [11] Like red algae, and in contrast to green algae and plants, glaucophytes store fixed carbon in the cytosol. [12] The most early-diverging genus is Cyanophora, which only has one or two plastids. When there are two, they are semi-connected. [13] Glaucophytes have mitochondria with flat ...
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 ...
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 ...
Therefore, exopolysaccharide-producing "soil algae" play a vital role in the ecology of the world's soils. The substance covers the outside of, for example, unicellular or filamentous green algae and cyanobacteria. Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life ...
Golenkinia is a genus of green algae first described in 1894 by Robert Chodat. [1] The genus is named for the Russian phycologist Mikhail Iljitsch Golenkin. [2] Golenkinia species live in fresh water (including bodies of black water such as Winyah Bay) [3] and are found around the world. [4]
Dunaliella is a single-celled, photosynthetic green alga, that is characteristic for its ability to outcompete other organisms and thrive in hypersaline environments. [1] It is mostly a marine organism, though there are a few freshwater species that tend to be more rare. [2]
