Paragraph A

Write a paragraph that explains, for each of the six main groups of organisms listed below:

• whether all organisms in that group are unicellular, or most of the organisms are unicellular, or most of the organisms are multicellular, or all of the organisms are multicellular
• whether organisms in that group are made of Prokaryotic or Eukaryotic cells.

Groups of organisms:

1. Bacteria
2. Archaea
3. Plants
4. Fungi
5. Protists
6. Animals

Paragraph B

In your second paragraph, you should describe the similarities shared between prokaryotic and eukaryotic cells. Identify the four cell structures, from the list below, that are part of the structure of BOTH prokaryotic and eukaryotic cells. For each of those four cell structures, write one complete sentence that states that prokaryotic and eukaryotic cells both have that cell structure. Each sentence should also include some wording that briefly describes the role of the structure in the cell.

1. Cell membrane
2. Nucleus
3. Cytoplasm
4. Mitochondria
5. Ribosomes
6. DNA
7. Pilus
8. Capsule

Paragraph C

Your third paragraph should describe the main ways, covered in Chapter 4, in which prokaryotic cells DIFFER from eukaryotic cells (the traits are listed below). For each of these traits, write one or two complete sentences contrasting the two cell types.

For each trait, make sure your sentences include:

• A statement that the two cell types (prokaryotic vs eukaryotic) differ in that trait
• A description of the differences; you must describe the characteristic of EACH type of cell, for each trait.

Traits:

1. Size of each cell
2. Presence or absence of a nucleus
3. Location of DNA within the cell
4. Presence or absence of other membrane-bound organelle
