biology interview questions: 36 Biology Interview Questions (With Example Answers)

Introduction

You’re on a biology interview and you need to know how to answer the cell biology questions. That’s where we come in! We’ve compiled this list of 36 biology interview questions that cover all areas of cell biology, including components and functions of cells, photosynthesis, autotrophism and more. These questions are great for interviews or tests as they help you learn about the subject matter while also giving you an opportunity to showcase your knowledge.

What are the components of a cell?

The cell wall is a rigid layer that surrounds the cell. It helps to protect the cells from damage and keeps them from bursting open when they get too full of water or nutrients.

The membrane around the nucleus is called a nuclear envelope, which contains proteins that help control what goes in and out of your DNA. These proteins also help to repair damaged DNA when necessary by making copies of important genes for use in repairing cells with broken DNA strands (this process is called transcription).

Chromosomes are found inside most eukaryotic cells’ nuclei; they contain all genetic information needed for life! Each chromosome has two long strings made up primarily by DNA but also some proteins (called histones) wrapped around it like thread on spools–you can think of these as being like little spools inside spools inside even bigger spools…and so on until you have enough “spaces” between each one where nothing else fits anymore!

Give examples of the major components of a cell.

To answer this question, you should be able to identify the major components of a cell. These include the cell membrane, nucleus, cytoplasm and other organelles. The cell membrane is a phospholipid bilayer that is necessary for maintaining the shape of the cell and regulating what enters or leaves it. Inside this layer lies another membrane called an endoplasmic reticulum (ER). This organelle has ribosomes attached to its surface where proteins are produced using genetic information from DNA; these proteins are then transported through pores in both membranes into either side of their respective environments before being secreted out by exocytosis or endocytosis processes if needed further processing elsewhere within your body or outside via diffusion through open gaps between cells’ outer walls called intercellular spaces

Identify parts (parts) of the cell.

• Cell membrane: The outermost layer of the cell, which is made of a double layer of phospholipids and proteins.
• Cell wall: A rigid layer that surrounds plant cells, acting as a protective barrier against dehydration and injury. It consists mostly of cellulose fibers arranged in an overlapping fashion to form an interlocking network.
• Cell nucleus: Contains DNA and other cellular material necessary for growth and reproduction; located in the center of eukaryotic cells (those with nuclei).
• Cytoplasm: The gelatinous material within both prokaryotic (“simple”) and eukaryotic (“complex”) cells; includes organelles such as ribosomes (protein synthesis) mitochondria (energy production), endoplasmic reticulum (lipid synthesis) etc..

The cytoplasm also contains all sorts of molecules floating around including enzymes that facilitate chemical reactions occurring inside your body right now!

Define what is a cell and identify its components.

• A cell is the smallest unit of life.
• The components of a cell include DNA, RNA, protein, ribosomes (protein factories), mitochondria (energy production), golgi apparatus (enables packaging and secretion of proteins), endoplasmic reticulum (produces lipids) and plasma membrane (protects contents).
• The plasma membrane is made up of lipids (fats), proteins and carbohydrates.

How do cells respond to stimuli?

Stimuli can be physical, chemical, or electrical. Cells respond to stimuli by releasing hormones and neurotransmitters. They can also change their shape.

Give examples of how cells respond to stimuli.

• Cells respond to stimuli by changing their shape, location and behavior.
• They also use their metabolism to respond to stimuli. For example, when you eat something spicy, your mouth will start to water because of the rise in temperature inside it; this is a response from your cells that causes them to produce more saliva so that they can cool down again.

Name some parts of a plant cell and their functions.

• Cell wall: A plant cell wall is composed of cellulose, hemicellulose and pectin. It provides support to the plant cell and protects it from mechanical damage.
• Cell membrane: The cell membrane separates the cytoplasm from its environment, regulates what enters or exits a cell through pores called channels or fenestrae (diagram below). It also controls movement of substances within the cytoplasm by selective transport mechanisms such as active transport (movement against concentration gradient), facilitated diffusion (movement with concentration gradient), osmosis (transfer of water across semipermeable membranes) etc., depending upon their chemical properties like charge density; molecular weight etc..
• Nucleus: This organelle contains DNA which encodes genes responsible for hereditary characteristics of an organism including growth patterns during development stages like embryogenesis etc..

Describe the different parts of a plant cell, where they are located and what they do.

The cell wall is a protective barrier for the cell. It helps to keep out harmful substances and also prevents the cell from swelling up when it absorbs water.

The membrane separates the inside of your plant cell from its surroundings, so you can think of it like an outer layer. The nucleus sits in here and contains genetic material that makes up all your genes (DNA). This is where most of your energy comes from, too!

Chloroplasts are tiny green structures found in leaves where photosynthesis occurs – they use sunlight to convert carbon dioxide into sugar molecules which provide food for plants, animals and humans alike! Mitochondria (singular “mitochondrion”) are tiny organelles found within cells that produce adenosine triphosphate (ATP), which is used as fuel by cells during respiration (the process whereby food breaks down into smaller molecules).

What is autotrophism? Explain how autotrophs obtain energy through photosynthesis or chemosynthesis.

Autotrophs are organisms that can produce their own food. Most autotrophs are plants, but some bacteria and fungi are also autotrophs.

The most common form of photosynthesis is called C3 carbon fixation. In this process, energy from sunlight is used to convert carbon dioxide into glucose (C6H12O6) with the help of chlorophyll and water via a number of intermediate steps called the Calvin cycle. This process results in one molecule of O2 being released for every molecule used during photosynthesis; therefore it’s considered an aerobic respiration pathway since oxygen is produced as a byproduct rather than consumed like anaerobic respiration does (eukaryotes like us breathe in oxygen).

Chemosynthesis describes how certain organisms obtain energy through chemical reactions rather than using light as an energy source like photosynthetic organisms do; instead they use hydrogen sulfide or methane found deep within ocean trenches where temperatures reach -5 degrees Fahrenheit (-20 Celsius).

Cell biology is one of the most important areas in biology because without it, we wouldn’t be alive

Cell biology is one of the most important areas in biology because without it, we wouldn’t be alive. The cell is the basic unit of all living things; it contains DNA and other molecules that make up its genetic material. A cell’s shape and size varies depending on its function in the body (for example: red blood cells are small; muscle cells are large). Cells also contain organelles such as mitochondria which produce energy for the cell to use during respiration or photosynthesis depending on whether they’re found within an animal or plant respectively. Cells come together to form tissues which can then be organized into organs like liver or kidney so that they work together efficiently to keep our bodies functioning properly!

Conclusion

We hope that this article has helped you learn more about cell biology and understand the importance of it. As we mentioned earlier, this field of study is very important because without cells, we wouldn’t be alive!
