Physiology :- Study of working mechanism of different parts of the body. Structure 4. It covers areas ranging from the structure of organisms to the subcellular unit of life. 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. Chemical Nature 6. How to use zoological in a sentence. Chitin is a large, structural polysaccharide made from chains of modified glucose. Morphology definition is - a branch of biology that deals with the form and structure of animals and plants. The term ‘zoology’ has been derived from the Ancient Greek ‘zōon’ which means animal and ‘logos’ meaning knowledge, or study. The zoological studies deal with the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct. Despite the complexity of the science, certain unifying concepts consolidate it into a single, coherent field. The life processes or characteristic phenomena of a group or category of living organisms. 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. Zoology definition: Zoology is the scientific study of animals. Notochord Definition. It encompasses all aspects of scientific knowledge about animals, like embryonic development, evolution, behavior, ecological distribution, and classification. ADVERTISEMENTS: In this article we will discuss about the meaning and classification of chordata.

It is considered one of the most traditional and popular structures in existence and is still dominant in governments, large organizations, religious groups, and corporations. Meaning of Chromosome 2. Molecular Organisation 7. Its history traces the study of the animal kingdom from ancient to modern times. The word ‘logos’ has a meaning of study or knowledge. Cytology :- Study of structures & functions of the cell. The zoology major is a gateway to the diverse areas of modern biology. Distribution and Production of Antibody 3. Histology :- Study of tissues. Zoologists study the structure, physiology, development and classification of animals. The efforts of the best minds in zoology had been directed for thirty years or Classification based on structure. See more. The animal life of a particular area or period: the zoology of Alaska; the zoology of the Pleistocene. A hierarchical organization is a structure where all the entities except the topmost are subordinate to another entity. Chitin is found in the exoskeletons of insects, the cell walls of fungi, and certain hard structures in invertebrates and fish. A chromosome is a string of DNA wrapped around associated proteins that give the connected nucleic acid bases a structure. It includes botany and zoology. Zoology is a vast branch of biology which deals with the scientific study of animal kingdom. Meaning of Nucleus 2. “Antibodies” Lecture Outcome After reading this lecture the scholars will be able to know about Definition of antibody, History, Domains, Structure, Variants, and Functions of Antibodies 3 Course: Immunology, Instructor: Abdul Majid, Department of Zoology , KUST Email: [email protected] 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. The term refers to the general aspects of biological form and arrangement of the parts of a plant or an animal. How to use morphology in a sentence. Structure of Nucleus. The notochord is an elastic rod which extends through Chordate organisms, providing rigid support. Hierarchy has a vertical chain of command with different levels of authority, for instance, between a superior and subordinate level in the company. 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. Special Types. Classification of Molecules. What is morphology? Chromosome Definition. Zoological definition, of or relating to zoology. Zoology, or animal biology, is the field of biology that involves the study of animals. They also study the habitats and ecology of animals. Zoology as a branch of life sciences involves work with animals, either in natural surroundings or in captivity. The major can be tailored to prepare students for advanced study and careers in many different areas: health professions and public health; law; life sciences research in university, government, and industrial settings; education including museum, nature center, secondary school, and college teaching; biotechnology; and environmental studies.
