1. The  answer  is "d". Prokaryotes are the more primitive cell types which lack most of the membrane bound  organelles. Bacteria and blue green algae are examples of prokaryotes. Eukaryote organisms consists of cells containing many membrane bound organelles. Higher plant and animal cells are made of  eukaryote cells. Examine the cell types below.

2. The answer is "b" nucleoid.  The genome is the total genetic makeup of a cell and is located on DNA molecules of the nucleoid of prokaryotes or the nucleus of eukaryotes.

3. The answer is "b" binary fission. You may want to check the glossary of the text for a definition for this term. Prokaryote cells and the two organelles replicate by binary fission. This process will be explained later in this program.

4 and 5. The answer for 4 is "c" and for 5 is "d".  This is a eukaryote cell with it's DNA in the nucleus in the form of chromosomes. This figure represents an eukaryote cell which may replicate by mitosis or meiosis.
