The below mentioned article provides a note on algae. Algae are eukaryotic photosynthetic thallophytes lacking archegonia. Although most of the taxonomic groups of algae include multicellular macroscopic organisms, there are also unicellular forms in majority of such groups. That is what justifies their inclusion among microorganisms. As a major group of living organisms, algae are highly heterogenous in size, morphological [...]
In this article we will discuss about the thallus structure of lichens with the help of diagrams. In a lichen thallus, the phyco-symbiont and the myco-symbiont are intimately associated, but their identity is maintained. On the basis of gross morphology, lichens are distinguished into three types — crustose, foliose and fruticose. The crustose lichens grow as a crust adhering closely [...]
