Science > Biology > Classification of Microbes, Protists, and Fungi > Lichens In the five-kingdom classification of Whittaker, there is no mention of some acellular organisms like viruses and viroids and lichens. A lichen is a long-living composite organism that arises from algae or cyanobacteria (or both) living among filaments of a fungus in a […]

Kingdom Fungi
Science > Biology > Classification of Microbes, Protists, and Fungi > Kingdom Fungi Kingdom Fungi: The fungi constitute a unique kingdom of heterotrophic organisms. They show a great diversity in morphology and habitat. e.g., yeast is used to make bread and beer. Other fungi cause diseases in plants and animals; wheat rust-causing Puccinia is an […]

Kingdom Protista
Science > Biology > Classification of Microbes, Protists, and Fungi > Kingdom Protista In the last article, we have discussed the Kingdom Monera. In this article, we shall study the Kingdom Protista. All single-celled eukaryotes are placed under Kingdom Protista (Greek – protistos – First of all), but the boundaries of this kingdom are not well […]

Kingdom Monera
Science > Biology > Classification of Microbes, Protists, and Fungi > Kingdom Monera The kingdom Monera is also referred as kingdom prokaryotae. Bacteria are the sole members of the Kingdom Monera. Organisms of kingdom monera are called lower-level organisms because no tissue-level organization is present in them. Their one cell is capable of performing all the functions […]
Science > Biology > Classification of Microbes, Protists, and Fungi > Brief Idea In this article, we shall get a brief idea of the classification of lower-level organisms i.e we shall study bird eye view of Kingdom Monera, Kingdom Protista, and Kingdom Fungi. In subsequent articles, we shall discuss the classification in detail. In lower-level […]

Salivary Glands
Science > Biology > Digestion and absorption in Human > Salivary Glands There are two sources of digestive enzymes: The glandular cells of the lining of the stomach and intestine, which directly pour their secretion into the lumen of the gut or the alimentary canal. Special glands such as the salivary glands, the liver and the […]

Binomial Nomenclature
Science > Biology > General Biology > Diversity of Living Organisms > Binomial Nomenclature Biologists follow universally accepted principles to provide scientific names to known organisms. Each name has two components – the Generic name (genus) and the specific epithet (species name). Hence the system is called binomial nomenclature. We can compare the generic (genus) […]

Taxonomic Hierarchy
Science > Biology > General Biology > Diversity of Living Organisms > Taxonomic Hierarchy In this article, we shall study the taxonomic hierarchy and the concept of species. The Concept of Species: A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding is called species. They are usually described in […]
Science > Biology > General Biology > Branches of Biology > Branches of Biology (Brief Idea) In the previous article, we have studied the importance of biology. In this article, we shall study different branches of biology. On the Basis of Kind of Organism: Depending upon the kind of organism, the branches of biology are […]
Science > Biology > Introduction to Biology > Importance of the Study of Biology List of Sub-Topics: Biology is the science that studies living things, including plants, animals, and human beings. It helps us understand life and the different processes that take place in living organisms, such as growth, reproduction, and interaction with the environment. […]
