Meaning for life science /
What is biological science?

The meaning for life science or “What is biological science” is a rather large topic and covers many aspects.

Life science is exactly that – the science that deals with life and living things, what affects them and how they interact. So, when we think about life science and biology, we think about all the metabolic processes that happen in living organisms. Processes such as gaseous exchange (in higher animals, what we call breathing), growth (different in plants and animals), reproduction (again, different between plants, animals and mushrooms), where each organism gets it's food (plants make it, animals eat it, mushrooms absorb it) and then what happens to it once it arrives in the body of the organism etc. etc.

As you can see, there are many topics to cover for each organism, and there are many organisms – plants (of which there are perennial, non-perennial, flowers, shrubs, trees, algae etc.), animals (of which there are mammals, fish, birds, crustaceans, moluscs, insects, arachnids, reptiles, amphibians etc. etc.), fungi (of which there are mushrooms, bracket fungi, rusts, molds etc. etc.), bacteria (of which there are some live in your body, others live in hot springs or in ice, some are used to make cheese, yoghurt or beer and others can kill you), and viruses (again, some can kill you but some are used for genetic engineering).

Apart from looking at each organism by itself, life sciences also looks at how they all interact together to create the balance of an ecosystem and how man has come along and upset the balance of various ecosystems. Life science also looks at what can be done to recreate the balances in the ecosystems that we have messed up.

Then there are the various disciplines within the life sciences – taxonomy (the naming of organisms), genetics, microbiology, entomology, botany, plant and animal pathology, medical and veterinary fields etc. etc.

Some famous biologists

Mr. Fleming (who discovered penicillin by accident) and Mr. Watson and Mr. Crick (who worked out the double helix structure of DNA and rightly won the Nobel Prize for it) also knew the meaning for life science.
