Nostoc is the most common genus of Cyanobacteria (blue-green algae). It is found in both terrestrial and aquatic habitats. Nostoc is also known as star jelly or spit of the moon due to its colonies, composed of filaments of moniliform cells in…
Chara is a multicellular submerged freshwater green alga of the class Charophyceae. It is usually found in freshwater ponds, lakes, tanks, etc. On the surfaces of the Chara, cyanobacteria have been found to grow as epiphytes. Chara is commonly known…
Oedogonium is a multicellular, filamentous, fresh water green alga of the class Chlorophyceae. It can be found in freshwater such as pools, tanks, ditches, etc. The young filaments of Oedogonium are found to be attached to some substrate. Salient Features…
Volvox is a free-floating freshwater planktonic green alga of the class Chlorophyceae. It is usually found in stagnant water, such as ponds, pools, etc. Volvox diverged from its unicellular predecessors approximately 200 million years ago. Salient Features of Volvox The…
Chlamydomonas is a unicellular, motile, green alga of the class Chlorophyceae. It is widely distributed and found mostly in stagnant water. Chlamydomonas is one of the most primitive eukaryotes in the plant kingdom. Salient Features of Chlamydomonas The salient features…
Vaucheria is a freshwater green alga of the class Xanthophyceae. It is found nearly worldwide, especially in lakes, canals, and wetlands. The terrestrial species remain attached to the substratum by colorless rhizoids. Salient Features of Vaucheria The salient features of…
Cyanobacteria are the most primitive types of organisms (plants) with simple prokaryotic cellular structures. With the help of an electron microscope, Pankratz and Bowen (1963) studied the structure of cyanobacterial cells. The detailed cell structure of cyanobacteria is as follows: Cell…
Reproduction in algae is the production of young ones (offspring) of the same kind as themselves. Generally, all three types of reproduction are observed in algae, such as: Vegetative Reproduction in Algae The method by which new individuals are formed…
Algae are chlorophyll-bearing autotrophic members of thallophytes comprising a large heterogeneous assemblage of relatively simple plants. Algae may be aquatic, semi-aquatic, or terrestrial in their habitat. In the sea, they make up the major part of the vegetation. On pools…
Algae are plants of simple structures. There exist a wide variety of thalli in algae, particularly in the vegetative plant body. The different forms show a definite range. The range of thallus is from the simplest, which consists of non-motile…
