Importance Of Biology To The Study Of Life

Biology is the scientific study of life. Life is recognized mainly by what living things do. Some of the properties and processes that are associated with life include; order, regulation, growth and development, energy processing, response to the environment, reproduction, evolution.

Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions. In multicellular organisms, similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems.

The basic structural and functional unit of life is the cells (comprise the body of the living organism).Cells reproduce and therefore, all existing cells are formed by the division of the old cells; thereby, leading to the growth of an organism. The genetic material of an organism is located in the nucleus which is the control center of the cell. Cells make up different parts of the human body, plants, fungi and essentially every living thing. There are different types of cells including eukaryotic cells and prokaryotic cells. Eukaryotic cells can be further distinguished as animal cells or plant cells. These cell differ from the more primitive prokaryotic cells because of the presence of the membranous organelles in the cytoplasm, a nuclear membrane and a chromosomal proteins. The nucleus in the eukaryotic cells holds the majority of the genetic material and controls all activity within the cell, analogous to a blueprint. DNA replication and transcription occurs in the nucleus. Translation of the mRNA on the other hand occurs in ribosomes, which carry out protein synthesis for the cell. Ribosomes are essential for protein assemble, including enzymes which are important for many cellular functions. There is also the endoplasmic reticulum, which has two types: smooth and rough. Smooth endoplasmic reticulum is responsible for lipid synthesis and process metabolic such as drug detoxification and lacks ribosomes. Cell membranes are also important and cell walls are found in plant cells. Both are responsible for regulating the entrance and exit of substances and
