The term "carbohydrate" comes from the Greek word sakharon meaning "sugar". In the field of chemistry, carbohydrates comprise the most common type of organic compounds with simple structures. A carbohydrate is an aldehyde , or one that contains other hydroxyl groups. The most basic carbohydrates are known as monosaccharides. They have the fundamental structure (C*H2O)n where 3 or more...
It is common to discuss fat as if it was a villainous substance that is bent to destroy our diets. However, they are beautiful tiny molecules composed of three hydrocarbon tails that are attached to a small coathanger-like molecule known as Glycerol. Similar to the other big organic molecules they perform crucial functions in the biology of both humans...
The size and shape of protozoa vary based on the types of species. For example, the causative agent of Kala azar, Leishmania donovani has a size range of 1 to 4 micrometers in length, while the Amoeba proteus is 600 micrometers or more in size. Some members of ciliates can reach 2,000 micrometers or 2mm.
Endospores are dormant, tough, resistant, and non-reproductive structures which are produced by gram-positive bacterial cell (such as bacillus, clostridium) in the phylum firmicutes during the unfavorable condition of the environment.
Most of the motile bacteria locomote by using threadlike appendages which is extending outward from the plasma membrane and cell wall is known as flagella. Flagella also known as flagellum (Singular form).
In this article, we will learn about the Habitat, structure, nutrition, characteristics, reproduction, locomotion of the Amoeba cell with diagram. Domain Eukaryota Phylum Amoebozoa Class Tubulinea Order Euamoebida Family Amoebidae Genus Amoeba Amoeba cell also known as the ameba or amoeboid. Amoeba is a unicellular eukaryotic organism which can alter their shape by extending and
Protozoa don’t have any cell walls, instead they contain pellicle. The structure of Protozoa is similar to the eukaryotic cells. Some examples of protozoa are Trypanosoma, Trichonympha, Plasmodium, Paramecium. Now, Protozoa is a strictly descriptive term, they are no longer recognized as a formal group in current biological classification systems. Protozoa are ubiquitous, which means
What is Prions? Prion is an abnormal or misfolded protein that causes fatal disease in animals and humans by transmitting their misfolded shape onto normal variants of the same protein. Prion causes untreatable, fatal, and transmissible neurodegenerative diseases in both humans and animals. In this disease, a progressive decline is occurring in brain function. In
