25 Biology Questions (and Their Answers)

Just as the mind and conscience arouse interest, life itself does not escape the curiosity of the human being who wishes to have knowledge of everything. Biology is normal to be an interesting science, because it seeks answers related to the functioning of life itself.

25 Biology Questions to Test Your Knowledge

In the following article you will find a selection of Biology questions (with their answers) that any student or interested in this science should know how to answer without problems. With that said, I begin.

1. What is the cell?

The cell is the fundamental unit of life. Whether we speak of a being formed by a cell (unicellular) or by a group of them (multicellular), this element is always present. Thanks to their differentiation in functions, evolution has given way to increasingly complex organisms.

2. Who was Robert Hooke?

Hooke was an English scientist who coined the word cell after seeing them for the first time. This researcher observed a sheet of cork with a microscope, seeing a network of voids (hence the cell name), although he did not know how to associate this with the their real functions of these small bodies microscopic.

3. What is the difference between prokaryotic and eukaryotic cells?

The main differences between the two major cell types are the fact that prokaryotes (eg. bacteria) do not present any organelles (complexes that perform functions) and their genetic material is free inside the free membrane, and not in a nucleus as in the case of eukaryotes.

4. And the difference between plant and animal cells?

The answer to this question about Biology is easy, the big differences are that only plant cells have a cell wall, which generate the rigidity that characterize plants, and have organelles known as chloroplasts, which are responsible for the photosynthesis.

5. Who was Louis Pasteur?

Louis Pasteur is considered the "father of modern microbiology", since thanks to his work he refuted the idea of ​​spontaneous generation, showing that life does not appear by chance. He is also known for his sterilization technique: pasteurization.

6. What does the theory of biogenesis say?

This Biology question is related to the previous researcher, since the theory of biogenesis indicates that a previous life is needed to generate life. That is, life is not generated from nothing.

7. What do you mean "sterilized"?

To say that an environment is sterilized means that in principle all life has been eliminated, even at the level of microorganisms, from that environment.

8. Who was Charles Darwin?

Darwin was an English naturalist, who, along with Russel Wallace, promoted the idea of ​​Biological evolutionary theory through natural selection, a mechanism that tries to ensure that whoever survives has a better chance of reproducing.

9. What is biological evolutionary theory?

Related to Darwin is evolutionary theory, which indicates that living beings today are the result of progressive changes in the reproductive successes and failures of the ancestors. These ideas eliminated the hand of God in the explanation of the creation of the species.

10. What is genetic material?

Quite an important Biology question. If you spoke earlier that the cell is the unit of life, the genetic material is the basis for it. In it, the information for the creation of the cell is stored, as well as all its functions.

11. What is duplication, transcription and translation all about?

As a general rule, the cell stores its information in the form of DNA. Duplication occurs when an identical copy of DNA is made for cell division. Transcription is the passage from DNA to a strand of messenger RNA, and translation is the passage of the latter into a protein.

12. What is a protein?

A protein is a chain of amino acids (AA), which the cell uses as a tool to carry out its functions.

13. What is the difference between DNA and RNA?

I will answer this question very briefly. Without going into much detail, the differences are at the structural and functional level.

14. Who was Gregor Mendel?

Mendel was a monk and naturalist who is considered the father of genetics for the famous studies of him with peas, unraveling many of the mysteries of genetic inheritance.

15. What is a gene?

DNA is made up of a chain of nucleic acids (NA). The gene is a fragment of this, and contains the information to create a specific protein, mainly.

16. What is the genetic code?

The genetic material has its own language. Simply put, the order of the ANs that make up DNA provides information, be it a gene or an initiation sequence, for example.

17. What is the cell cycle in eukaryotes?

Eukaryotic cells follow a life cycle, and their purpose is cell division. This presents four phases, differentiated into two large groups: the interface, where the cell is prepared for its division; and the M phase, where the partition takes place in more than one cell.

18. What are the differences between mitosis and meiosis?

There are two types of cell division, which differ mainly in their outcome. While in mitosis two identical cells are formed, in meiosis it ends with four cells and each has a single DNA strand, instead of two.

19. What is a mutation?

This Biology question refers to one of the errors that can occur in DNA. The mutation is nothing but a change in the sequence of a gene, changing the meaning of this information.

20. What is apoptosis about?

As we talk about proliferation, cells also have programmed cell death. This process is known as apoptosis.

21. What is metabolism?

Metabolism refers to all chemical or physicochemical reactions carried out by cells or organisms.

22. What is an ecosystem?

All living things, such as animals and plants, have a relationship both with each other and with the environment that surrounds them. The whole of this is what we know as an ecosystem.

23. What differentiates gymnosperms from angiosperms?

The answer to this plant-related question is as follows: gymnosperms do not have showy flowers, unlike angiosperms.

24. What differentiates invertebrates from vertebrates?

Another general classification, in this case referring to the animal kingdom, is the division between vertebrates and invertebrates. The former have a bone structure, and the latter do not.

25. What types of reproduction are there?

Generically, there are two types of reproduction: asexual and sexual. The difference is that the second makes use of gametes (eg. sperm).
