Levels of Biological Organization
Integrated Science 4

Name:
Per.
Macroscopic to Microscopic
 The following terms reflect various levels of organization that pertain to all vertebrates. These
randomly assorted levels of organization represent both macroscopic and microscopic views of
vertebrates.
atoms, macromolecules, cells, organs, populations, organisms, organ systems, tissues, molecules.
1. Organize and list the levels of organization by size.
2. Draw a line between the levels that separate the macroscopic and microscopic views of vertebrates.
3. Label the levels as largest, smallest, macroscopic and microscopic.
Genentic Organization

All vertebrates are eukaryotic (organisms with enclosed nucleus), therefore their genetic material is
located within the nucleus and is further organized in heretible units passed from generation to
generation.
1. Define the following terms.

nucleus –

DNA –

chromosome –

gene –

cell –
2. Organize the terms above to accurately represent the organization of genetic material within eukaryotic
cells.

Understanding the organization and relationship among these levels is crucial to the understanding of
genetics and evolution. However, one obstacle to this understanding is the extremely small size of the
nuclei, chromosomes, genes and DNA. The use of analogies is a valuable technique to help visualize
these complex, hard-to-observe relationships. An analogy creates a relationship between two things
that are otherwise not connected.
3. Read the following analogy. Circle the terms within the analogy that correlate to each of the genetic
terms defined above. Match each set of correlated terms in the space below based example provided.
GENETIC ORGANIZATION ANALOGY – HARRY POTTER SERIES
Imagine a set of books, perhaps the Harry Potter series. The individual books are contained within a box
on a shelf. Each book contains a distinct portion of the overall story. Within each book are chapters. The
combinations of 26 letters of the alphabet are arranged to make the variation of words that tell the story of a
young wizard’s life – Harry Potter.
Example:
- box – nucleus
Your turn! Record your circled terms and their corresponding genetic terms below:
4. In the space provided below create an analogy of your own that explains the organization of genetic
material. Circle the terms analogous to the levels of genetic organization and create a key for the
correlated terms.
