What is biology? Biology is a common term that is used in our daily lives. Biology is used everywhere, in towns, villages, industries, in your bus or trainway home and even when thinking. But what does it entail? Which concepts does biology support? All these questions will be answered right here on this post. Therefore, stay tuned and continue reading to grasp the whole package of knowledge about Biology. At the end, we will recommend you a link where you can get the best biology answers when stuck with your biology homework, exams or tests.
The meaning of biology can be traced in the land of the Greeks where “bios” means life and “logo” means study. Hence, scientists refer to biology as the science of life. In short, biology is the scientific study of the life of a living organism and the process that occur in them. When we talk about living organisms, we indeed refer to the organisms that possess life. These are animals and plants. These life factors are commonly referred to as biotic factors.
In today’s modern tendency, biology has integrated with other scientific fields to improve the life of living organisms. Some of these integrated scientific fields include chemistry, physics and medicine. This has resulted in biophysics, biochemistry and biomedicine-an effective improvement in the area of science. Having that perspective in mind, let us dive to some of the basic concepts of biology that will amaze you. Do not forget to tell all your friends about this. It’s fascinating.
The idea of biology is a framework that governs the principles in which biological processes take place. These biological principles are:
Regardless of their uniqueness, all living organisms have traits either biological, chemical or physical those are common in them. For example, all living organisms have cells which are the basic component that builds the body of a living organism. When scientists thoroughly analyze these cells, they possess common components that are similar in human and bacteria. Moreover, the function of an organism is determined by how its cells interact gives us a more concrete conclusion that the cells of organisms have the same functioning altogether.
The basic unity of organisms does not only occur in their cell functioning but also their cells origin. In 1855, a German pathologist suggested a theory that all living cells originate from the preexisting cells of an organism. This theory has been confirmed true through the cycle of the zygote to the fetus and other meaningful examples. All organisms indeed have the same cell structure, function and composition. This gives the idea that they also have the same original origin.
Another common origin of life gives a well-illustrated example of the chemical substance called DNA (deoxyribonucleic acid) that is available in the form of genes. DNA helps in the transmission of genetic information from a parent organism to its offspring. All the transmission pattern of this genetic information is the same in all living organisms.
In case of mutation, there are always some changes in the genes which are given effect to variations. Such variations can either be of benefit or disadvantage to the organisms. Therefore, the similarities to these variations can impact a survival power to the organism during a natural selection.
The concept of homeostasis can be explained well in the theory of a French physiologist Claude Bernard. He stated that all the essential mechanisms that occur in organisms have only one object which is to preserve the conditions of life constantly no matter their variations. Homeostasis is a scientific condition that aims in maintaining a constant internal environment in living organisms.
The main aim of homeostasis is to help the single organism to survive in every varied condition. This concept was later extending to cover all areas of the earth that possess the life of an organism.
All organisms regardless of their common cells components, they possess different diversities in their species in their natural population. Our eyes can easily see these variations in variety. Moreover, they can be conducted through lab tests, e.g., when Charles Darwin conducted a lab test, he confirmed that variations could alter constitutes of DNA known as nucleotides. Nucleotides affect the chromosomes and later they are transferred to the offspring.
It is evident that whether a human or bacteria, all living organism can reproduce which gives rise to a new generation. Since it’s only through reproduction that cells originate from preexisting cells, the characteristics of an organism can be well maintained in the future generations.
The study of the interrelationship between living organisms and their environment is called Ecology. Ecology is an essential branch of biology due to the study of how human and animal activities affect the earth. This welfare is very vital to the existence of organisms.
Charles Darwin suggested the theory of evolution. This is commonly known as the theory of natural selection which talks more about the survival for the fittest. Survival for the fittest is a well-defined organic theory that depends on the time basis. The study of the fossil is concrete evidence of the existence of evolution in the earth. Others include the research of RNA, DNA, embryological development and comparative study of the organism structures.
Biology constituents the study of how the cells in high organism function. The biologist has studied cells in plants such as mitochondria, lysosomes etc. which have some similarities of the cells and their role in human. This study is the hallmark of what biology is.
All living organisms possess tissues and organs that build up the entire body. In plants, there are tissues such as xylem and phloem while in animals, there are tissues such as muscular tissues and blood tissues.
There are many branches of biology which we are going to discuss in our next post. Therefore, stay updated on our latest release so that you don’t miss a lot about biology. However, in brief, there are majorly two branches of biology –Zoology (the study of animals) and botany (the study of plants).
