In this article, we shall study the characteristics and examples of Division Thallophyta. (Greek – Thallus – plant body without root, stem, and leaves; phyton – a plant) Characteristics of Division Thallophyta: Members of division Thallophyta are the most primitive and simple plants. The plant body is not differentiated into root, stem, and leaves. They are […]
Category: General Biology
In this article, we shall get a general idea of the classification of plants. In the next articles, we shall study the classification of plants in detail. Characteristics of Kingdom Plantae: Kingdom Plantae consists of all plants which are multicellular eukaryotes with cell walls. All plants contain plastids. Plastids are a double-membrane organelle that possesses photosynthetic […]
Viruses
Science > Biology > Classification of Microbes, Protists, and Fungi > Viruses In the five-kingdom classification of Whittaker, there is no mention of some acellular organisms like viruses and viroids and lichens. Viruses did not find a place in classification since they are not truly ‘living’ if we understand living as those organisms that have […]
Lichens
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 […]
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 […]
