| True or False? You can see chromosomes during interphase | false
🗑
|
||||
| True or False? You can see chromosomes during cell division | True
🗑
|
||||
| What are the two main stages of cell division? | Mitosis and Cytokinesis
🗑
|
||||
| What are the differences between cell division in plant and animal cells? | the plant cell builds a wall to divide and split, the animal cell pinches it to divide.

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.
