naming or nomenclature we use today was introduced by Carolus Linnaeus in the eighteenth century. In Binomial nomenclature, the first name is the generic name beginning with a capital letter whereas the second name is the species name which begins with a small letter. Example – <i>Homo</i> <i>sapiens</i> where <i>Homo</i> is a genus name and <i>sapiens</i> is a species name.
Certain conventions are followed while writing the scientific names:
1. The name of the genus begins with a capital letter.
2. The name of the species begins with a small letter.
3. When printed, the scientific name is given in italics.
4. When written by hand, the genus name and the species name have to be underlined separately.

(a) To develop interest and awareness about wild animals in the public.
(b) The Zoos are involved in the conservation of many endangered species of wild life. To conserve the wild life, special attention is being given to the protection of natural habitats and ecosystems and the captive breeding of wild animals.

“Taxonomy is the study of principles and procedures of classification.”
Taxonomy includes study of following 4 points:
(1) Identification: Identification of living organisms
(2) Nomenclature: Nomenclature of living organisms
(3) Classification: Classification of living organisms in groups
(4) Affinities: Study of inter relationship between living organisms

It is the same
Taxon, plural Taxa, any unit used in the science of biological classification, or taxonomy. Taxa are arranged in a hierarchy from kingdom to subspecies, a given taxon ordinarily including several taxa of lower rank.
Gaurav Seth 5 years, 5 months ago
TAXON
Each unit or category of classification is termed as a taxon. It represents a rank. For example, the basic level of classification is species, followed by genus, family, order, class, phylum or division, in ascending order. The highest level of classification is known as kingdom.

1) Biodiversity- the variety of plants and animals life in a particular habitat, a high level of which is usually considered to be important and desirable.
2) Nomenclature- system of names/terms/ the rules for forming these terms in a particular field of arts or sciences.

Key is a taxonomical aid that helps in identification of plant and animal species. These keys are based on similarities and dissimilarities in characters, generally in a pair called couplet.
Each statement in a taxonomic key is referred to as a lead. For categorizing each taxonomic rank, such as family, genus, species, etc., different keys are used. It is also useful in identification of unknown organisms.
Keys are of two types- indented and bracketed keys. Indented key provides a sequence of choices between two or more statements while in bracketed key, a pair of contrasting characters are used.

It is our backbone which extends in the mid axis of the back (posterior) part of our trunk from head to the lower (inferior) extremity of trunk. Together with the sternum and rib, it forms the supporting frame work of our trunk. It support and rotate the head, suspends the viscera, protect vital organs, provides attachment to limb girdles, facilitates some movement of the trunk and houses the spinal cord. Vertebral column make two-fifth of total weight of body. The length of human vertebral column is 71 cm. (28 Inc.) in adult male and about. 61 cm (24 m) in an average adult female.

An aster is a cellular structure shaped like a star, consisting of a centrosome and its associated microtubules during the early stages of mitosis in an animal cell. Asters do not form during mitosis in plants. It is A star-shaped structure formed in the cytoplasm of an animal cell during mitosis, having raylike microtubules that surround the centrosome.

Common Fundamental characteristics are considered for the purpose of classification of animals.
If we consider specific characteristics, then each organism will be placed in a separate group and the entire objective of classification would not be achieved.
Classification of animals is also important in comparing different organisms and judging their individual evolutionary significance. If only a single characteristic is considered, then this objective would not be achieved.

Growth is defined as inversible increase in the number of cells or mass of living structure. If we consider increase in body mass at growth, non living objects like sand mounts grow too. Hence growth cannot be taken as a defining property if living organisms. Though it is a characteristics of living organisms . In case of non - living growth is external but in case of living growth is internal.
Reproduction :- Unicellular organisms reproduce by cell division. In multicellular organisms reproduction mostly refers to sexual reproduction and some of them reproduce asexually also. Reproduction cannot be considered an inclusive defining characteristics of living organisms of the following.
In single celled organism growth and reproduction are synonym as increased in no. of cells is considered as growth as well reproduction. Organisms like mule and liger can't reproduce fertile offspring.

- Bilateral and protostomial eucoelomate eumetazoa with metamerically segmented body and each segment bearing a pair of jointed locomotory appendages.
- “Arthopoda” literally means animals bearing jointed feet (Gr., arthron = jointed + podos = foot).
- These are extremely successful animals due to a protective exoskeleton and jointed appendages.
- That is why, more than 8 and half lac arthropod species are known as against about 2 and half lac species of the remaining animals.

Definition
A centrosome is an organelle found in cells that consists of two centrioles. A centriole is a structure found in a cell that is comprised of microtubules that are arranged in a particular way.
-
Size
A centrosome is of variable size but always bigger than a centriole. A centriole has dimensions that are approximately 500 nm long and 200 nm wide.
-
Formation
The pericentriolar material helps form the centrosome by organizing the centrioles. Proteins starting with SPD-2 recruit other proteins such as SAS-4, SAS-5, and SAS-6 to form the centriole.
-
Location
The centrosome occurs near the nucleus, and after it has copied itself, on opposite sides of the nucleus. The centriole can occur either near the nucleus or near the cell membrane.
-
Function
The function of the centrosome is to produce the spindle during mitosis and to help regulate intracellular transport. The function of the centriole is to form the centrosome and to form the basal body that gives rise to cilia and flagella

Karyokinesis:
Karyokinesis is the biological process involving the division of a cell’s nucleus during mitosis or meiosis.
It is divided into four stages –prophase, metaphase, anaphase, and telophase.

The cellular components are called the Cell Organelles. These cell organelles are membrane-bound, present within the cells and are distinct in their structures and functions. They coordinate with their functions efficiently for the normal functioning of the cell. Few of them functions providing shape and support, whereas some are involved in the locomotion and reproduction of a cell. There are various organelles present within the cell and are classified into three categories based on the presence or absence of membrane.
Organelles without membrane: The Cell wall, Ribosomes, and Cytoskeleton are membrane-bound cell organelles. They are present both in prokaryotic cell and the eukaryotic cell.
Single membrane-bound organelles: Vacuole, Lysosome, Golgi Apparatus, Endoplasmic Reticulum are single membrane-bound organelles present only in a eukaryotic cell.
Double membrane-bound organelles: Mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.

The taxonomic hierarchy is a systematic framework in classification in which taxonomic groups are arranged in definite order, from higher to lower categories. Each category is considered as a taxonomic unit and represents a Taxon.
Classification of Mango
Kingdom - Plantae
Division - Angiospermae
Class -Dicotyledonae
Order - Sapindales
Family - Anacardiaceae
Genus - Mangifera
Species - indica

In biology, a family is a taxonomic rank, or a taxon at that rank. Each family contains one or more genera. The next important rank is that of order. Usually, the name of the family ends with a "idae" for animals, and "aceae" for plants. Family is, in turn, more specific. Some families in the order Carnivora, for example, are Canidae (dogs, wolves, foxes), Felidae (cats), Mephitidae (skunks), and Ursidae (bears). There are 12 total families in the order Carnivora.
