Commercial and industrial algae cultivation has numerous uses, including production of nutraceuticals such as omega-3 fatty acids (as algal oil) [97] [98] [99] or natural food colorants and dyes, food, fertilizers, bioplastics, chemical feedstock (raw material), protein-rich animal/aquaculture feed, pharmaceuticals, and algal fuel, [100] and ...
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
The inclusion of additional polysaccharides in algal cells walls is used as a feature for algal taxonomy. Mannans: They form microfibrils in the cell walls of a number of marine green algae including those from the genera, Codium, Dasycladus, and Acetabularia as well as in the walls of some red algae, like Porphyra and Bangia. Xylans:
Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Viridiplantae, together with red algae and glaucophyte algae, form the supergroup Primoplantae, also known as Archaeplastida or Plantae sensu lato. The ancestral green alga was a unicellular flagellate. [20]
Harmful Algal blooms are colonies of microscopic algae that grow out of control. They can be damaging to people, wildlife and the environment. How harmful algal blooms, or colonies of microscopic ...
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. [1] They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few ...
Algae are the most common group of epiphytes in marine systems. [15] Photosynthetic epiphytes account for a large amount of the photosynthesis in systems in which they occur. [ 16 ] This is typically between 20 and 60% of the total primary production of the ecosystem. [ 15 ]
Filamentous algae of the genus Cladophora, which are predominantly found in fresh water, have diploid sporophytes and haploid gametophytes which are externally indistinguishable. [20] No living land plant has equally dominant sporophytes and gametophytes, although some theories of the evolution of alternation of generations suggest that ...
