Cell Structure and Function

The cell is the structural and functional unit of cellular organisation that serves as its fundamental structural and functional unit. It contains a complete set of different kinds of units necessary to permit its own growth and reproduction from simple nutrients, all of which are contained within a selective and relative semi permeable membrane.  Biotechnology […]

In terms of biology, the function is a natural phenomenon in diversity or natural selection, which changes organisms’ organs, traits and behaviour with time.  In other words, it is based on the theory of evolution, which says all the species are somehow related in terms of their origin but changes with time. These changes are

Flagella, also known as the motility or locomotor organelle, is a hair-like appendage that extends from the cell membrane. They are larger in size and length than pili and fimbriae. Their body is rigid and slender in appearance. The ability of bacteria to swim in liquid media is attributed to the rotational movement of their

Our bodies have cells that will help us to heal naturally from multiple viruses. There are multiple instances where multiple viruses attack your body, and for such a situation, we have cells that help the body. Such cells are known as B cells that produce antibodies and keep your health in good condition. When any

Autosomes are any chromosomes that serve a purpose other than determining an individual’s gender. Allosomes are genes that play a role in sexual preference determination. In the human genome, there are 23 pairs of chromosomes: 22 autosomes and one allosome (sex chromosome), which contains chromosomes XX (for females) and XY (for males) (for male). What

It is possible to define apoptosis as a type of cell death where a planned series of cells dies without spreading toxic substances into the surrounding environment. It is also referred to as programmed cell death or cellular suicide in some circles. This type of programmed cell death is the most well-understood of the three.

Antibody is also known as  immunoglobulin. It is a protective protein synthesis  by our  immune system ,fighting with foreign substances, called an antigen. A wide range of substances are present  by the body as antigens, including disease-causing organisms and other insect related toxins when insects bite .Biochemically Antibodies are proteinaceous in nature. It is Also

Introduction The word ‘tissue’ comes from the French word ‘tissu’, the past participle of the verb tisser, which means ‘to weave.’ A tissue is a collection of cells which share common origin, similar basic structures and perform the same function in an organism. Histology is the branch of Biology that deals with the study of

A tissue is a collection of cells that are related to one another and perform comparable functions in an organism. Tissues make up the entire contents of the body, including structures and numerous organs. The animal body is made up of four fundamental types of tissues, each with its own origin and function. They are

Introduction A tissue is a collection of cells which share common origin, similar basic structures and perform the same function in an organism.Tissue is a biological organizational level between cells and an organ. A tissue is a collection of cells and extracellular matrix from the exact origin. The word ‘tissue’ comes from the French word
