|

|---|---|---|---|---|---|
| Cell division | the process by which a cell divides into two new daughter cells
🗑
|
||||
| Mitosis | the first stage, division of the cell nucleus
🗑
|
||||
| Cytokinesis | the second stage,division of the cytoplasm
🗑
|
||||
| Chromatids | each chromosome consists of these two identical "sisters" after each chromosome is replicated, or copied
🗑
|
||||
| Centromeres | where each pair of chromatids is attached
🗑
|
||||
| Interphase | "in-between" period of growth in cell division/DNA is replicated/the cell grows
🗑
|
||||
| Cell cycle | is the series of events that cells go through as they grow and divide
🗑
|
||||
| Prophase | the first and longest phase of mitosis/the chromosomes become visible
🗑
|
||||
| Centrioles | two tiny structures located in the cytoplasm near the nuclear envelope
🗑
|
||||
| Spindle | a fanlike microtubule structure that helps separate the chromosomes
🗑
|
||||
| Metaphase | the second phase of mitosis/the chromosomes line up across the center of the cell
🗑
|
||||
| Anaphase | the third phase/the centromeres that join the sister chromatids split, allowing the sisters to become individual chromosomes
🗑
|
||||
| Telophase | the fourth and final phase/the chromosomes begin to disperse into a tangle of dense material
🗑
|
||||
| Cyclin | regulates the cell cycle
🗑
|
||||
| Cancer | a disorder in which some of the body's own cells lose the ability to control growth
🗑
|
||||
| As a cell becomes larger | volume increases faster than its surface area
🗑
|
||||
| As a cell grows, it | places more demand on its DNA/uses up food and oxygen more quickly
🗑
|
||||
| Problems that growth causes for cells | DNA overload/Expelling waste
🗑
|
||||
| If a cell's DNA were not copied before cell division, the cell could | be stopped from dividing by cyclins
🗑
|
||||
| When a cell divides | each daughter cell receives its own copy of the parent cell's DNA
🗑
|
||||
| Phases of mitosis | Interphase, prophase, metaphase, anaphase, telophase
🗑
|
||||
| Plant cells | have a cell plate
🗑
|
||||
| Contact with other cells | can stop cell from growing
🗑
|
||||
| In eukaryote cells, the timing of the cell cycle is regulated by | Cyclins
🗑
|
||||
| Cancer cells form masses of cells called | Tumors
🗑

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.
