One would assume that the meaning of life would never need to be defined. Let’s pose the question to you, “what is life?”. You would have to think a while unless you hand me the dictionary definition. You see with issues like this, one stumbles over the answer and even when the answer is delivered they tend to be vague. Alright, let’s change the question. “What’re living things?”. This seems easier, doesn’t it? Then let’s tackle it.
The dictionary definition something like this given below. “An individual form of life, such as a bacterium, protist, fungus, plant or animal consisting of a singular cell or a complex of cells in which cell organelles or organs work together to carry out the various processes of life.” But turn and ask your friend the same question, “what are living things?”. Chances are he or she will associate life or a living being with movement, that is unless he or she refuses to answer the question.
You see, most of us identify life through movement, we breathe, our chest moves up and down, it makes it easy to point out the person and call him alive. But what about a leaf, if the color you look at is green, it is alive. But you see the conundrum arises when one reminds you that there are plants that exist that aren’t green. So, now what is the solution? There is no definite solution, to be honest. On the safe side, one can assume that if something can procreate or reproduce, it can be called alive or a living being.
Birds, insects, animals, trees, human beings, are few examples of living things as they have same characteristic features like eating, breathing, reproduction, growth, and development, etc.
