1.) In your own words, write a definition for the term organelle. 1.1 1.) In your own words, write a definition for the term organelle. An organelle is a tiny organ within a cell that has its own unique function or job.

1.1 1.1 2.) Use the following terms in the same sentence: Prokaryotic, nucleus, and eukaryotic A prokaryotic cell is a cell that does NOT have a nucleus while a eukaryotic cell does have a nucleus.

3.) Cell size is limited by the 1.1 3.) Cell size is limited by the A. Thickness of the cell wall B. Size of the cell’s nucleus C. Cell’s surface area-to-volume ratio. D. Amount of cytoplasm in a cell

4.) What are the three parts of the cell theory? 1.1 4.) What are the three parts of the cell theory? 1.) All organisms are made of one or more cells. 2.) The cell is the basic unit of all life. 3.) All cells come from existing cells.

5.) Name three structures that every cell has. 1.1 5.) Name three structures that every cell has. All cells have a cell membrane. All cells have cytoplasm. All cells have genetic material (DNA).

6.) Give two ways that archaebacteria are different from eubacteria 1.1 6.) Give two ways that archaebacteria are different from eubacteria Archaebacteria have a different type of cell wall and cell membrane and, Archaebacteria have different ribosomes. More like those of eukaryotes.

The organism is a prokaryote because; 7.) You have discovered a new single-celled organism. It has a cell wall, ribosomes, and long, circular DNA. Is it a eukaryote or prokaryote? Explain. The organism is a prokaryote because; It has long circular DNA and Doesn’t have a nucleus.

8.) One of your students brings you a cell about the size of a period at the end of a sentence. It is a single cell, but it also forms chains. What characteristics would this cell have if the organism is a eukaryote? If the cell were a eukaryote it would have the following; A nucleus Membrane bound organelles

8.) Continued: Prokaryote If the cell were a prokaryote you would not see a nucleus

9.) What type of organism does the picture show? It is a prokaryote because it does not have a nucleus. It has long circular DNA instead.

10.) Which structure helps the organism move? The flagellum helps the prokaryotic organism move.

11.) What part of the organism doest the letter “A” represent? Letter “A” represents the DNA for the prokaryotic cell. A
