Volvox is a genus of freshwater algae found in ponds and ditches, even in shallow puddles. [7] According to Charles Joseph Chamberlain , [ 13 ] "The most favorable place to look for it is in the deeper ponds, lagoons , and ditches which receive an abundance of rain water.
Habitat type can influence thallus length, which varies from 0.5 to 50 cm. [9] The habit of the thallus is used to divide species into two major groups: those with >10 cm thallus height, and those that measure between 2–3 cm. [9] Like many other algal species, Hypnea exhibits a high degree of phenotypic plasticity and cryptic diversity which ...
Various polymers can be created from algae, which can be especially useful in the creation of bioplastics. These include hybrid plastics, cellulose-based plastics, poly-lactic acid, and bio-polyethylene. [132] Several companies have begun to produce algae polymers commercially, including for use in flip-flops [133] and in surf boards. [134]
Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
Ulvaria obscura is a common marine algae, typically identified in algal blooms referred to as "Green Tides". [3] [4] The species is distinct in its ability to produce the neurotransmitter dopamine as a herbivore defense mechanism.
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
With the world's annual celebration of his birth mere weeks away, it turns out one of the most revered figures who ever walked the Earth likely didn't look like the pictures of him.
Halymenia a genus of a macroscopic red algae that grows in oceans worldwide. [1] Species have been found in cold temperate areas but the highest diversity is found in warm temperate and tropical regions. For example, 41 names have been reported for the Indo-Pacific (Guiry & Guiry, 2011).
