Life Science Quiz for Living Things That Excited Now

Updated on: July 5, 2024

Delighted Ways for Grade Out of Lifespan on Earth

Want to remind you now about the life science quiz. That is not without saying the words. Hope you like it. All Living things, even the green plants respire throughout the life cycle. Thus, animals, as well as plants, respire because it is the lifeline of them. As a result, the respiration process is only done through the oxygen present in the air. Oxygen is used to convert food into energy and carbon dioxide (CO₂) given out. And so, all living things respire to build their body, repair, and get energy as well. Although, it is a vital characteristic of all living things. Living things example- lion, elephant, man, bacteria, etc.

The various parts of plants and their functions are mainly classified in two parts. One above the ground or second below the ground. Furthermore, the shoot system (leaf, stem, fruits, flowers) is above the ground whereas the root is below the ground.

In fact, classification is the common way of sorting for all living things. Growing new species of living organisms helps to find out specific characteristics. Even more, which helps to divide the group. That is the motto of life science. In the exam and test, questions were asked from the life science quiz for the general science part. These can help you prepare for exams like UPSC CSE, SSC–CGL, PSC, GRE, GMAT, and business schools. Thus, get all the interesting questions-answers in the life science quiz. You can increase your life science knowledge. In the same way, learn the correct answers to questions given here now so well.

FAQs

What is life science?

It is a branch of science. Here the living things and the life processes of those living things are studied. The branches of science that belong to it are biology, medicine, and sometimes anthropology or sociology.

Who is called the father of living science?

Aristotle, the ancient Greek philosopher regarded as the Father of Biology. Besides, he is also regarded as the Father of Zoology as well. Because, his concept of species claimed the functions and behavior of individual animals. Which led him to do classification with two kingdoms that are plants and animals.

What is the theory or hypothesis of life science?

Theory of life science states that all living things are composed of cells. These cells are functional and structural units of life for all organisms. Since, cells are even very tiny. And so, these can be visible only and only by microscope.

What are the major branches of life sciences?

Five major branches of life sciences are as follows

Ecology (study of organisms)
Botany (Study of plants)
Zoology (Study of animals)
Microbiology (Study of microorganisms)
Entomology (Study of insects)

What are the advantages of life sciences?

Through life science we get to know the environment around us and other living species. As a result, we can try to save the entire living species with the knowledge we get. We can even know ourselves. Answers to the creation of humans and where they came from.
