  1. What is a eukaryotic cell?

  2. What is a prokaryotic cell?
  1. A lion (Panthera leo) and a tiger (Panthera tigris) are both species of cats.  How are these cats similar?  How are they different?
  1. You have three different types of muscles in your body:  smooth, cardiac, and skeletal.  Why do you think scientists categorized muscles in this manner?  Use facts to explain your thinking.

Answer Key/Rubric

  1. A eukaryotic cell holds its genetic material inside of a nucleus.  The nucleus is enclosed by a membrane.

  2. A prokaryotic cell does not have a nucleus or other organelles.  Its DNA is not organized into chromosomes.
  1.  Acceptable responses may include, but are not limited to:

Similarities:

  • Same kingdom, phylum, class, order, family, and genus
  • Live in the wild
  • Have sharp claws
  • Have large, sharp teeth
  • Carnivores
  • Fast runners
  • Long tails

Differences:

  • Live in groups (Lions live in a pride.  Tigers live in a streak.)
  • Lions have tan coloring.

  1. Acceptable responses may include, but are not limited to:

    • The three types of muscles are found in different places in your body.
      1. Smooth muscles make up organs such as the esophagus, small intestine, and bladder.
      2. Cardiac muscles are only found in the heart.
      3. Skeletal muscles are connected to your skeleton.
    • The three types of muscles have different functions.
      1. Smooth muscles are found in different organs and are necessary for the organs to function.
      2. Cardiac muscles are necessary for the heart to function properly.
