25 biology questions (and their answers)

Just as the mind and the conscience arouse interest, life itself does not escape the curiosity of the human being who wants to know everything. It’s normal that biology is an interesting science, Because he seeks answers related to the very functioning of life.

25 biology questions to concretize 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 it without problem. Having said that, I am starting.

1. What is the cell?

The cell is the fundamental unity of life. Whether it is a being made up of a cell (unicellular) or a set of them (multicellular), this element is always present. Thanks to their differentiation of 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 cork leaf under a microscope, seeing a network of voids (hence the name of the cell), although he did not know how to associate it with their actual functions of these tiny microscopic bodies.

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

    The main differences between the two main types of cells are the fact that prokaryotes (e.g. bacteria) do not have organelles inside (complexes that perform functions) and its 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 generates the rigidity that characterizes plants, and have organelles called chloroplasts, which are responsible for photosynthesis.

    5. Who was Louis Pasteur?

    Louis Pasteur is considered the “father of modern microbiology” because of his work he refuted the idea of ​​spontaneous generation, Proving 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 question of biology is related to the previous researcher, as the theory of biogenesis indicates that a previous life is necessary to generate life. In other words, life is not generated from nothing.

      7. What does “sterilized” mean?

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

      8. Who was Charles Darwin?

      Darwin was an English naturalist who, along with Russel Wallace, he pushed the idea of ​​the theory of biological evolution through natural selection, A mechanism that attempts to ensure that those who survive are more likely to reproduce.

        9. What is the theory of biological evolution?

        Evolutionary theory is related to Darwin, who indicates that present-day living things are the result of gradual changes in reproductive successes and ancestors’ failures. These ideas removed the hand of God to explain the creation of the species.

        10. What is genetic material?

        A very important question on biology. If before I said that the cell is the unit of life, the genetic material is the basis. It stores the information for the creation of the cell, as well as all of its functions.

        11. What are duplication, transcription and translation?

        Typically, 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 of DNA to a messenger RNA strand, And translation is the transition from the latter to a protein.

        12. What is a protein?

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

        13. What is the difference between DNA and RNA?

        I will answer this question very concisely. Without going into details, the differences are at the structural and functional level.

        14. Who was Gregor Mendel?

        Mendel was a monk and naturalist considered the father of genetics for his famous studies of peas, revealing many mysteries of genetic inheritance.

        15. What is a gene?

        DNA is made up of a strand of nucleic acid (AN). The gene is a fragment of it, and contains the information to create a particular protein, mainly.

        16. What is the genetic code?

        Genetic material has its own language. Simply put, the order of the NAs that make up DNA provides information, whether it’s a gene or an initiation sequence, for example.

        17. What is the cell cycle in eukaryotes?

        Eukaryotic cells go through 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 phase M, where partition into more than one cell takes place.

        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 strand of DNA, 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, Change the meaning of this information.

          20. What is apoptosis?

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

          21. What is metabolism?

          Metabolism refers to all chemical or physico-chemical 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 around them. All of this is what we know as an ecosystem.

            23. What differentiates gymnosperms from angiosperms?

            The answer to this plant-related question is: Gymnosperms do not have showy flowers, whereas angiosperms do.

            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 latter uses gametes (eg sperm).
