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 […]

Brief Idea of Classification of Microbes, Protists, and Fungi

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 […]

Gastric Glands

Science > Biology > Digestion and absorption in Human > Gastric Glands The gastric glands are numerous, simple or branched tubular glands present in the mucosa of the stomach. They are located in different regions of the stomach. Gastric glands secrete digestive juice and mucus. There are three types of gastric glands, distinguished from one another […]

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 […]

Importance of the Study of Biology

Science > Biology > Introduction to Biology > Importance of the Study of Biology Biology is a branch of science which studies living beings that all plants and animals including humans. It is a word derived from Greek words (Greek: bios = life; logos = study). No one can say when the study of biology exactly […]

Three Domains of Life

Science > Biology > General Biology > Diversity of Living Organisms > Three Domains of Life Prior to 1969 organisms were classified into two kingdoms: the Plant Kingdom and the Animal Kingdom and on the basis of a cell, organisms were classified into two categories Prokaryotae or Monera (which comprised bacteria) and Eukaryotae (which comprised animals, plants, fungi, […]

Need for Classification of Living Beings

Science > Biology > General Biology > Diversity of Living Organisms > Need for Classification of Living Beings Scientists have identified and named 1.7 to 1.8 million species of living organisms. Of these, about 1.2 million are animal species while 0.5 million are plant species. The group of insects is the largest group with 1.025 […]
