Why Living Organisms Are Classified | Biology Blog

                                        Living Organisms 

Hello Guys!


We'll talk about why it's important to categorize living things. Therefore, before moving on to the subject, let's first talk about something really fundamental: What is Living?

 

When we consider what it means to be alive, our minds automatically focus on characteristics like growth, metabolism, the ability to self-replicate, etc. 

Let's talk about each of them:

Growth -  Growth refers to an abrupt rise in size and quantity. Similar to how our fingers reach a specific height before stopping to develop, our height also rises for a limited time before stopping, however in plants, growth continues continually for the duration of their lives. Cell division is also how unicellular creature grow.  But as I mentioned earlier, growth is another name for a gain in mass. Using these standards, we can also assert that nonliving things, such as the collection of objects on any surface, mountains, etc., grow.  Consequently, the result is that internal growth is a trait of living organisms and occurs when they are alive.

Reproduction - Reproduction is the biological process by which a parent can create kids of same species. Therefore, this is another trait of a living being. There are two different types of reproduction processes: asexual reproduction and sexual reproduction.  The reverse of sexual reproduction is asexual reproduction, in which only one parent is responsible for producing their own sort of children.

          

        However, there is one exception to this rule: not all organisms are capable of reproducing, i.e., some couples are unable to conceive a child as a result of infertility. Therefore, we cannot conclude that reproduction is a characteristic shared by all living things.

Metabolism - Chemical compounds make up every living thing. The size of the compounds can vary, and they can ultimately transform into specific biomolecules. Chemical reactions are used to describe this change. Basically, our bodies go through a huge number of chemical reactions, and the aggregate of all of these is what is known as metabolism. Catabolism is the process by which complex molecules undergo chemical reactions to become simpler ones, while anabolism is the process by which a simpler substance becomes complex, as in the case of our muscular system. Such a characteristic is unique to living things because it is absent from nonliving things.

The need for Classification - On earth, there are many different kinds of bacteria, animals, and plants. The size, form, color, habitat, and many other characteristics of all these species vary. As a result, studying each of them is impossible. As a result, scientists have developed a system to categorize all living things. These methods of classification are based on rules and principles that allow identification, nomenclature and finally classification of organisms.
