Why Learning Biological Facts Matters for Students
Biology talks about life. Everything living around us is related to the study of biology. Whether it is a microorganism or a massive animal, they all fall under biology. Now, every living species inculcates different biological systems and works differently. There are some mind-blowing biological facts that we didn't even know but actually exist in nature. These interesting biology facts will help you to gain a better knowledge about the subject and the environment that surrounds us. This article outlines all the interesting biology facts that you need to know and understand how the living world works.
Importance of studying Biology
Biology is an important facet of Science that sheds light on how all the living organisms who are a part of this world, operate. Their interaction, evolution and adaptation is studied thoroughly so that students learn about how everything functions. It is an extremely scoring subject as it is quite factual and at the same time, interesting. The practical assignments that are a part of Biology are also very rational and fun-filled. Biology always paves the way for further research into a particular subject so that advancements can be made in those fields. It shapes the different careers such as that of a doctor, engineer, environmentalist, chemist, scientist and so forth.
Supersized Molecules
This comes under biology science facts where you might know that almost everything in this world is made up of millions of molecules. Though the size of these varies from simple to complex types of molecule. A simple molecule can be an oxygen molecule whereas a complex molecule is an organic structure. But did you know where the biggest molecule resides? Well, the interesting biology fact is that it is inside you! Yes, the chromosome is the biggest molecule.
Is The Appendix Useful?
Nobody liked the appendix, right? In biology science facts it is considered as a body part that lost its functions many years ago and all it does is get infected from time to time, give you pain and cause appendicitis. This biological fact will tell you how important the appendix has become. Recently, it was discovered that the appendix is a bacterium that can be useful for your digestive system and its functioning. The appendix helps to get relief from the tension of the hectic bustle of the gut. The amazing facts on biology are that it keeps the gut’s bacterial residents beaten up by breeding with them.
The Goosebumps Evolution
This is an interesting biology fact that will tell you about the Goosebumps evolution over the years. Goosebumps occur when the muscles near each hair on our body tense up and stand erect. But in furry animals, this has a different reaction which is not a basic biology fact. When mammals bungle up their fleece when threatened, they look bigger and very dangerous.
Australian Flower Spider
According to Eats Their Mother When Lacking Food Biology science fact mentions cannibalism is predominant in many animals and especially spider species. This interesting biology fact is true and usually, cannibalism is seen during sexual encounters. But a certain type of Australian Flower spider breed eats their mother when they do not find food. It is the mother who sacrifices herself and encourages her young kids to attack and feed on her body. This biological fact gave you Goosebumps, didn't it?
Eyelash Invaders
Now, this Biological fact might creep you out a little bit but depending on your age, it is very much possible that you have eyelash mites. These are tiny creatures that reside on old cells on the skin and the natural oil which is sebum formed by the human hair follicles. They grow almost transparent and possibly a third of a millimetre. You cannot see them through your naked eye. Put your eyelash hair under a microscope and see what you find. This is a biological science fact and therefore almost half of the world population has these. Snakes Never Close Their
Snakes Eyes
One of the amazing facts on biology tells you about how snakes never close their eyes. Even while sleeping, they have their eyes open. The basic biology fact is that snakes do not have eyelids naturally. They aren’t born with one. They just have eye scales that will cover their eyes which you must have seen in many animal planet's shows. They shed their eye scales when they shed their skin.
These were just some interesting facts about biology. Biology as a study is vast and learning amazing facts on biology is endless. You can never know too much when it comes to biology. The human species is evolving every day and with it so are the facts.
About Cells
When you learn facts about cells for biology, it is a vast subject. The basic biology fact is that all living things are made up of cells. These cells are made up of organelles and proteins where its main function is to organize. Motor cells are the longest cells in the human body. Biology facts about cells tell us that there are 75 to 100 trillion cells in the human body. Usually, this comes under the top 5 facts about biology when studying.

FAQs on Essential Biological Facts in Biology
1. What are some of the most fundamental facts or principles in biology?
Biology is built upon several core principles that explain how all life works. The most essential facts include:
- Cell Theory: All living organisms are composed of one or more cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.
- Gene Theory: Traits are inherited through gene transmission. Genes are located on chromosomes and consist of DNA.
- Evolution by Natural Selection: The differential survival and reproduction of individuals due to differences in phenotype. It is a primary driver of life's diversity.
- Homeostasis: The ability of an organism to maintain a stable internal environment despite changes in external conditions.
2. Why do newborn babies have more bones than adults?
A newborn baby has around 300 bones, while an adult human has 206. This difference exists because many of a baby's 'bones' are actually made of soft cartilage, which provides flexibility for birth and rapid growth. As the child grows, this cartilage hardens and many of these smaller bones fuse together to form the larger, stronger bones of the adult skeleton. For example, the skull bones and the bones in the pelvis are separate at birth and join later in life.
3. How do developing bird embryos get oxygen inside a hard eggshell?
Although an eggshell appears solid, it is actually a semi-permeable membrane covered in thousands of microscopic pores. These pores allow for gas exchange with the outside environment. Oxygen diffuses into the egg through these pores, and carbon dioxide, a waste product of the embryo's metabolism, diffuses out. Inside the egg, a special membrane called the chorioallantois is rich in blood vessels and lies just beneath the shell, functioning much like a lung to absorb the oxygen.
4. What is the biological purpose of goosebumps?
Goosebumps are a fascinating vestigial reflex from our evolutionary ancestors. They are caused by the contraction of tiny muscles called arrector pili, which are attached to each hair follicle. This contraction makes the hair stand on end. For our fur-covered ancestors, this had two main purposes:
- Insulation: Trapping a layer of air close to the skin to stay warm in the cold.
- Intimidation: Making them appear larger to scare off predators.
5. What is the biological difference between veins and arteries?
While it's true that arteries typically carry oxygenated blood away from the heart and veins carry deoxygenated blood toward it (with the exception of pulmonary circulation), their key biological differences lie in their structure and function. Arteries have thick, muscular, and elastic walls to withstand the high pressure of blood being pumped directly from the heart. Veins, on the other hand, have thinner walls as the blood pressure is much lower. Veins also contain one-way valves to prevent the backflow of blood as it returns to the heart against gravity.
6. Is the human appendix a completely useless organ?
The appendix was long thought to be a useless vestigial organ, but modern biology suggests it has important functions. Evidence shows the appendix acts as a safe house for beneficial gut bacteria. During a severe intestinal illness that flushes out the gut, the bacteria stored in the appendix can emerge to help repopulate the digestive system and restore balance. It also contains a high concentration of lymphoid tissue, indicating it plays a role in the immune system.
7. Why is the brain often more active during sleep than when we are awake?
While our bodies rest, our brains are hard at work performing crucial maintenance tasks. During sleep, especially in the Rapid Eye Movement (REM) stage, brain activity can be as high as or even higher than during wakefulness. This activity is associated with several key functions:
- Memory Consolidation: The brain processes information from the day, strengthening neural connections to form long-term memories.
- Cellular Repair: The brain clears out metabolic waste products, like beta-amyloid, that accumulate during waking hours.
- Learning and Skill Formation: The brain rehearses and solidifies new skills learned during the day.
8. What makes DNA the 'blueprint of life'?
DNA (Deoxyribonucleic Acid) is called the 'blueprint of life' because it contains the complete set of instructions for building, maintaining, and reproducing an organism. This information is encoded in the sequence of its four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). This genetic code dictates everything from your eye colour to how your cells function by providing the template for creating proteins—the complex molecules that do most of the work in our bodies.
9. How can some organisms survive in extreme environments like volcanic vents?
Organisms that thrive in extreme conditions are called extremophiles. Those near deep-sea volcanic vents survive without sunlight through a process called chemosynthesis. Instead of using light energy (photosynthesis), these bacteria and archaea use chemical energy from compounds like hydrogen sulphide released by the vents to produce food. This forms the base of a unique food web, allowing other animals like tube worms and crabs to survive in total darkness and under immense pressure.
