| Describe the history of microscopes. | Microscopes started out as simple light microscopes, moving on to electron microscopes like scanning el. mic., trasmission em, and scanning tunneling microscopes.

| Describe the differences between a prokaryotic and a eukaryotic cell, and identify their parts. | P: don't have membrane-bound organelles
usually unicellular
E: are mem. bound and generally multicellular
p: have ribosomes, DNA, cell walls
e: have only nuclei, chromosomes, ERs, etc.

| Explain the difference between a scanning electron microscope and a transmission electron microscope and their uses. | Scanning scan surafces to see the cell's 3D shape. Transmission stud the insides of cells.

| Suppose you discovered a new type of plant. Applying the cell theory, what can you say for certain about this organism? | It:
Has cells
It's basic structure is cells
It came from preexisting plant cells.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
