    Modern taxonomy, also known as biosystematics, is a branch of systematics that identifies taxonomic affinity based on evolutionary, genetic, and morphological characteristics. The typological concept has been abandoned. Every category is the result of a process of evolution.

    In cell biology, the nucleus is a membrane-bound organelle found in eukaryotic cells. Eukaryotes usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm; and the nuclear matrix (which includes the nuclear lamina), a network within the nucleus that adds mechanical support, much like the cytoskeleton supports the cell as a whole.The cell nucleus contains all of the cell's genome, except for the small amount of mitochondrial DNA and, in plant cells, plastid DNA. Nuclear DNA is organized as multiple long linear molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function. The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression—the nucleus is, therefore, the control center of the cell.

    In the eukaryotic cell - _It is an organelle _ enclosed by nuclear membrane _ it contains most of cell's genetic material. FUNCTION:- _The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) . _ carries the genes, structures that contain the hereditary information.

    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. It is also useful in identification of unknown organisms.

    Reproduction is the ability to produce younger ones. It cannot be considered as a defining property of the living organism because in unicellular organism the increase in number of cells is considered as growth as well reproduction. Mule is a cross of female horse and a male donkey cannot produce fertile offspring though they are living.
