There are three major branches of biology – botany, zoology and microbiology. Botany is the branch of biology which deals with the study of different aspects of plants. Theophrastus is known as the father of Botany. Zoology is the branch of biology connected with the study of different aspects of animals.

Options include: anatomy, biophysics, cell and molecular biology, computational biology, ecology and evolution, environmental biology, forensic biology, genetics, marine biology, microbiology, molecular biosciences, natural science, neurobiology, physiology, zoology and many others.

There are three main recognized branches of biology, which include botany, zoology, and microbiology.

Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology.

There are three major branches of biology – botany, zoology and microbiology. Botany is the branch of biology which deals with the study of different aspects of plants.

Here are the different branches of biology (or divisions of biology) and their definitions & their related resources.

• Anatomy. Anatomy is the branch of biology that deals with the study of the structure of organisms and their parts.
• Biochemistry.
• Biophysics.
• Biotechnology.
• Botany.
• Cell Biology.
• Ecology.
• Evolution.

Careers you could pursue with a biology degree include:

• Research scientist.
• Pharmacologist.
• Biologist.
• Ecologist.
• Nature conservation officer.
• Biotechnologist.
• Forensic scientist.
• Government agency roles.

Kingdom is the broadest division. While scientists currently disagree as to how many kingdoms there are, most support a five-kingdom (Animalia, Plantae, Protista, Monera, and Fungi) system. The lowest division is species, which consists of organisms that are capable of interbreeding to produce fertile offspring.

biochemistry, cell biology, microbiology, botany, zoology are the major 5 branches of biology.

Top ten biological discoveries

• Aristotle (384–322 BC): classification of living things.
• Galen (129–161 AD): early medical experimentation.
• Antonie van Leeuwenhoek (1632–1723): microbiology.
• Carl Linnaeus (1707–1775): modern taxonomy.
• Charles Darwin (1809–1882): theory of evolution.
• Gregor Mendel (1822–1884): modern genetics.

The three main divisions of life are Domain Eukarya, Domain Bacteria and Domain Archaea.

Living things are divided into five kingdoms: animal, plant, fungi, protist and monera. Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.

Click on a domain to begin exploring. This coexisted with a scheme dividing life into two main divisions: the Prokaryotae (bacteria, etc.) and the Eukaryotae (animals, plants, fungi, and protists).

Plants, Animals, Protists, Fungi, Archaebacteria, Eubacteria. How are organism placed into their kingdoms?

Eight kingdoms model

• The first two kingdoms of life: Plantae and Animalia.
• The third kingdom: Protista.
• The fourth kingdom: Fungi.
• The fifth kingdom: Bacteria (Monera)
• The sixth kingdom: Archaebacteria.
• The seventh kingdom: Chromista.
• The eighth kingdom: Archezoa.
• Kingdom Protozoa sensu Cavalier-Smith.

Answer. Domain is the largest taxon.

Until recently the system devised by Robert Whittaker in 1968 was widely adopted. Whittaker’s classification scheme recognizes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

Whittaker

In biology, kingdom (Latin: regnum, plural regna) is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla….Summary.

Haeckel 1866	3 kingdoms
Woese et al. 1977	6 kingdoms
Cavalier-Smith 1993	8 kingdoms
Cavalier-Smith 1998	6 kingdoms
Ruggiero et al. 2015	7 kingdoms

The Seven Kingdoms of Life

Kingdom	When Evolved	Structure
Chromista	1.2 billion years ago	Unicellular
Fungi	1 billion years ago	Unicellular or Multicellular
Animalia	700 million years ago	Multicellular
Plantae	500 million years ago	Multicellular

There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species.

Domain is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. There are three domains of life, the Archaea, the Bacteria, and the Eucarya.

Characteristics of the Six Kingdoms of Organisms

• Archaebacteria. Archaebacteria are the most recent addition to the kingdoms of organisms.
• Eubacteria. Eubacteria are also single-celled bacterial organisms.
• Fungi. The Fungi kingdom is recognizable to us as mushrooms, molds, mildews and yeasts.
• Protista.
• Plants.
• Animals.

Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world.

species

The three-domains of Carl Woese’s Classification system include archaea, bacteria, eukaryote, and six kingdoms are Archaebacteria (ancient bacteria), Eubacteria (true bacteria), Protista, Fungi, Plantae, Animalia.

Plants, Animals, Protists, Fungi, Archaebacteria, Eubacteria.

The most influential system, the ‘Whittaker’ five kingdom structure, recognises Monera (prokaryotes) and four eukaryotic kingdoms: Animalia (Metazoa), Plantae, Fungi and Protista.

How Many Domain Names are There in All? According to the latest data from Verisign, there were 359.8 million registered domain names at the close of 2019’s third quarter. There were 5.1 million more domain name registrations over the previous quarter, marking a 1.4 percent increase.
