Biology 101, Chapter 1, Introduction: Life Defined

In addition to Biology 101:
• Apologia Biology Exp. 1.1 - Biological Classification  (worksheet)

What is Life?
There are four criteria to actually be able to say something is alive.
1. All life forms contain deoxyribonucleic acid (DNA).
2. All life forms have a method to extract energy from their surroundings and convert it into energy that is useful to them.
3. All life forms can sense changes in their surroundings and respond to those changes.
4. All life forms reproduce.
(Apologia Biology, p. 1)

King Philip and the Biological Classification System - Taxonomy

During the video, he gives the genus and species for a mountain lion.  On the screen it says, "Felis Concolor."  The spelling and name are correct, but it should be written as Felis concolor with only the first word capitalized and both words italicized.
The genus and species are the only two categories in the Biological Classification system whose proper names will be italicized.
The proper name of a species is always written in lowercase.

Order of the Biological Classification system:
Kingdom, Phylum, Class, Order, Family, Genusspecies

The words themselves, "kingdom, phylum, class, order, family, genus, and species" are not capitalized in sentences unless they precede the proper name.  Such as Kingdom Animalia, or Phylum Chordata.
The proper name of the species is never capitalized.

Use this mnemonic to help you remember the order:  King Phillip Cried Out, "For Goodness Sake!"
Write your own mnemonic.  =)

There are 5 kingdoms.
Each is further divided into the levels mentioned in the video. 

--Kingdom Monera consists of bacteria, and are made of one cell.  Their cells have no nucleus and therefore are called prokaryotic cells. (pro-carry-ah-tic)
(All other organisms have a nucleus, and have what are called eukaryotic cells.)
--Kingdom Protista is made up of other organisms such as amoebas, and are also made of one cell, but their cells have a nucleus - a eukaryotic cell.  (you-carry-ah-tic)
Members of this kingdom are larger than bacteria but still are too small to be seen without a microscope.  

Anything you can see with the naked eye is made of many cells.

Part 1

Part 2 Single-celled kingdoms Monera and Protista

Part 3 Multi-celled kingdoms Fungi, Plantae, and Anamalia


  1. I decided to do Bio 101 with my son this year. I recently had him write a mnemonic for the classifications and he came up with "Krazy Penguins Cook Only Fun Gyro Sandwiches." LOL.

    I'll be checking back often to see all of your great posts about it!


  2. Oh, I like that! I like Gyros. =)
    A few of the kids in my class had names beginning w/ those letters so we really had a lot of fun with that. =)

  3. I'm so glad I found you, Marty! Thanks for the Exp. 1.1 worksheet!

  4. Marty,
    I am considering the Biology 101 switch from the Apologia Biology and was wondering if I could ask your input. I have an 8th grader and an 11th grader that we are wanting to get back to doing science together and are starting Biology together. How long does it take to get through the program? Is it interesting enough in the videos to keep attention? We are just not needing such a specific nitty gritty science class.Also, my son seems to learn better with videos.

    Thank you!

    1. Karen, I put my reply to you here:

      =) =)
