In this article we will discuss about ectomycorrhizal versus endomycorrhizal fungi. Ectomycorrhizal Fungi: In ectomycorrhizal association, the fungus forms a mantle or sheath over the surface of fine lateral roots of the host trees and sends some hyphae into the intercellular spaces of the outer cortex forming a so-called Hartignet. Arbuscules and vesicles, characteristically present in endomycorrhizae are absent. The [...]
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 morphological and cellular characteristics of algae. Morphological Characteristics of Algae: Algae exhibit a very wide range of morphological diversity. The simplest forms are unicellular, microscopic, motile or non-motile eukaryotic cells. They may be spherical (Protococcus, Chlorella), or pyriform (Chlamydomonas). When motile (Volvox, Chlamydomonas) the cells are generally provided with a pair of [...]
