Biology Worksheets to Help You Better Understand The World Around You!

biology worksheetsWhen you wake up in the morning each day, how do you decide what to eat?  Do you listen to your cravings (as unhealthy as they may be) or do you reach for something that you know is good for you?  For instance, why do you crave sugar so much despite all the negative things you hear about it?  As a matter of fact, the type of food you crave can be traced back to biology.  By exploring these questions using biology, we can understand that our cravings for natural high-content sugar substances go back to the days when humans had to hunt and gather to survive for high caloric substances to store fat over long periods of time.

As you can see, biology is all around us, and it is the study of our lives as well as everyone elses.  With all this information and insight into human life and everyday instance, why would we not want to learn biology?  There are plenty of worksheets with helpfully structure questions that you can go through to better understand and apply the basic concepts and ideas of biology.  Today, we are going to take you though some of the basic principles and ideas of biology that can be found on biology worksheets.  Grab a healthy snack to curb your sweet tooth and let’s get started!

Basic Principals of Biology

Before we get into what you can expect to see on biology worksheets, it is important to know some biology basics.  Let’s go over some of the basic principles of biology that you should be away of first.

  • Cell Theory:  Cells are basic units of life, and the cell theory deals with the idea that all living organisms are composed of cells.
  • Gene Theory:  In human beings, traits are inherited and passed on through the process of gene transmission.  These genes are found on chromosomes in our body and consist of DNA.
  • Evolution:  The idea of evolution is very important in biology, and encompasses the idea that genetic change in a population or group can be inherited over the span of several generations.  These genetic changes may be small, large, or not so noticeable at all.
  • Homeostasis:  Homeostasis is a human or organisms ability to maintain a consistent internal environment in response to outside environmental changes.
  • Thermodynamics:  Thermodynamics deals with the idea that energy is constant and that energy transformation is not always completely effective or efficient.

Biology Worksheet Example Questions

Now that we know the important parts of biology that you should be aware of, let’s take a look at some example questions that you are likely to find on biology worksheets pertaining to the biology basics.

biology worksheetsCell Biology:

  1. Be able to define the organelles of a cell:  Eukaryotic Cells, Nucleus, Mitochondria, Endoplasmic reticulum, Golgi apparatus, and Chloroplast.
  2. Identify the parts of a cell:  Ribosomes, Lysosomes, Cell Membrane, and the Cell wall.
  3. Know the different between Eukaryotes and Prokaryotes.
  4. Know that bacteria do not have the follow: organelles, nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, chloroplast, and lysosomes.
  5. Be aware that bacteria do contain the following:  ribosomes, cell membrane, and a cell wall.

DNA:  For Gene theory, you should know the basic process of DNA, and there are plenty of helpful worksheets that can allow you to practice this.  Try to fill in these blanks for better DNA knowledge and preparation!

  • These two sides of DNA held together by weak ____ bonds
  • This will always pair with cytosine

  • This is the process of copying DNA
  • What is composed of a sugar, a base, and a phosphate?
  • These are the sections of DNA that are used to code for a trait
  • A ____ replaces thymine in RNA.
  • ____ carries the message of DNA to ribosomes
  • The long form of DNA is known as ____ acid
  • This is the type of sugar found in DNA
  • A DNA’s structure was established by Watson and _____
  • The sides of the DNA ladder are composed of sugar and _____
  • This will always pairs with thymine
  • Where is DNA found in the cell?

Evolution:  Let’s take a look at some questions used in evolution worksheets that can give you a better grasp and understanding of its concepts.  Decide whether or not the following questions are true or false:

  • Only 200 years ago, many believed that Earth was only 6,000 years old.
  • Artificial selection occurs when nature selects beneficial traits for an organism.
  • All of the individual Galápagos Islands are similar to each other.
  • Malthus held the idea that human populations grow faster than their resources.
  • Lamarck was the first scientists to propose the idea that species evolve by natural selection.
  • Lamarck’s idea of inheritance of acquired characteristics is a widely accepted scientific theory.
  • Fossils the determining factor in proving to Darwin that species can evolve.
  • The term “fitness” is used to refer to an organism’s ability to outrun its predators.
  • Darwin published his findings after he returned to England from the voyage on the Beagle.
  • According to Darwin, natural selection is what occurs, and evolution is how it happens natural selection happens.
  • Darwin found fossils from the seas in the mountains during his journey on the Beagle.
  • Darwin documented that Galápagos tortoises have differently shaped shells depending on where they live.
  • Darwin’s book on natural selection changed science forever.
