Essays on Biology

Why is biology needed as a science? What role does it play in our lives? Why is she necessarily taught at school?

Biology is a science about the structure of all living nature. To know biology is to know the laws by which all organisms live. Man is a part of nature, although he created civilization. We all went out of nature and will return there.

It is useful to know the branch of biology - botany, which studies plants. Having become acquainted with botany, you can distinguish plants. You can find out which of them are poisonous, which are useful, which and for what you can use. It is also important for a botanist to know in order to be able to grow plants and engage in agriculture, if this is to be done. Yes, even indoor plants can not be grown without basic knowledge of botany.

It is equally important to know zoology - the science of animals that live side by side with us humans. It is important to understand the value of wild animals, which seem to bring no benefit to humans. But every creature in nature maintains a balance in it, at which everyone else can live.

And to know the anatomy is generally necessary for every person who respects himself and his body. Anatomy is the science of the structure of the human body. Knowledge from this area must be remembered every day, taking care of your health and the health of your family members.

It turns out that biology is a science about life itself, no more, no less. No wonder its name comes from the word “bios”, which means “life”.

Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations.


Biology is defined as the study of life while psychology examines the human mind and its processes, especially those affecting behavior. Biological perspective links biology and psychology by focusing on the analysis of human behavior based on biological and physical evidence.


Why is biology important? As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life.


Chemical biology deals with how chemistry can be applied to solve biological problems while biochemistry is the study of the chemistry of biology. In general, the chemical biology major focuses on small molecules while the biochemistry major focuses on proteins and nucleic acids.
