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 Asexual Reproduction Sexual Reproduction Vegetative Reproduction in Algae The method…
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…
