It encompasses all aspects of scientific knowledge about animals, like embryonic development, evolution, behavior, ecological distribution, and classification. Later on, in 1934 the German biologist J. Hammerling, demonstra­ted that the nucleus determines the characters of a cell and ultimately the characters of an individual.

As nouns the difference between zoology and ecology is that zoology is that part of biology which relates to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct while ecology is the branch of biology dealing with the relationships of organisms with their environment and with each other. Structure of Nucleus. The notochord is an elastic rod which extends through Chordate organisms, providing rigid support. This extremely versatile molecule can form solid structures on its own as in insect wings, or … The term ‘zoology’ has been derived from the Ancient Greek ‘zōon’ which means animal and ‘logos’ meaning knowledge, or study.

This discipline of science comprises three sub-disciplines that are botany (study of plants), Zoology (study of animals) and Microbiology (study of microorganisms). The word zoology is derived from the Ancient Greek word ‘zoon,’ meaning the animal. Structural biology is a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules (especially proteins, made up of amino acids, RNA or DNA, made up of nucleotides, and membranes, made up of lipids), how they acquire the structures they have, and how alterations in their structures affect their function. Th… The zoological studies deal with the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct.

The term anatomy also refers to the study of biological structure but usually suggests study of the details of either gross or microscopic structure. The study of life is the literal meaning of the term ‘biology’ and ‘zoology’ as taken as being synonymous with ‘animal biology’. In the more derived Chordates, the Vertebrates, the notochord is replaced by the vertebral column, and becomes the cartilaginous substance between vertebrae.The notochord can be seen in the image below, of a lancelet.Lancelets are some of the simplest Chordates. Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. The term ‘zoology’ has been derived from the Ancient Greek ‘zōon’ which means animal and ‘logos’ meaning knowledge, or study. BRANCHES OF ZOOLOGY :- Morphology :- Study of external structures of living organisms. A hierarchical organization is a structure where all the entities except the topmost are subordinate to another entity. Zoological definition is - of, relating to, or concerned with zoology. The study of animals is a large and diverse branch of science. It mainly deals with the structural anatomy, physiology, embryology, evolution, classification, habits, growth and differentiation, and distribution of types of cells, including both the dead or living. They also study the habitats and ecology of animals. ADVERTISEMENTS: In this article we will discuss about:- 1. Entomology definition is - a branch of zoology that deals with insects.
