|---|---|---|---|---|---|
| selectively permeable | the ability of the cell membrane to allow certain materials to pass through and prevents other from passing through
🗑
|
||||
| diffusion | one way in which some types of materials can pass through the cell membrane
🗑
|
||||
| osmosis | the physical process of water moving throuh the cell membrane from a region of greater abundance to one of lesser abundance
🗑
|
||||
| active transport | process by which cellular energy is used to transport material across the cell membrane
🗑
|
||||
| passive transport | the movement of materials across the cell membrane without the use of cellular energy
🗑
|
||||
| cell division | process during which one cell gives rise to two new cells
🗑
|
||||
| cell division | process that produces two cells identical to the parent cell
🗑
|
||||
| cell membrane | provides protection for the cell
🗑
|
||||
| cell membrane | keeps the cell's inner content together
🗑
|
||||
| cell membrane | regulates the movement of materials into and out of the cell
🗑
|
||||
| cell division | responsibnle for the total number of cells in an organism
🗑
|
||||
| centromere | structure that holds chromatids together
🗑
|
||||
| centriole | a structue found in animal cell division that is not usually found in plant cell division
🗑
|
||||
| permeable | membrane that allows all material to pass through
🗑
|
||||
| mitosis | process in which the nucleus of a cell divides into two nuclei and the formation of two new daughter cells begins
🗑
|
||||
| interphase | stage of cell division when the cell is performing its life functions
🗑
|
||||
| interphase | stage of cell division when there is no evidence of cell division
🗑
|
||||
| interphase | individual chromosomes are not visible
🗑
|
||||
| chromatin | appearance of chromosomes during interphase
🗑
|
||||
| duplication | process by which the individual chromosomes have made a copy of themselves
🗑
|
||||
| chromosome | pair of sister chromatids
🗑
|
||||
| chromosomes | become visible during late interphase
🗑
|
||||
| chromatids | pair of identical chromosomes connected by centromere
🗑
|
||||
| prophase | chromosomes become even more visible
🗑
|
||||
| prophase | second stage of cell division
🗑
|
||||
| prophase | each chromosome appears as a pair of chromatids attached by centromere
🗑
|
||||
| prophase | centrioles move to opposite side of cell
🗑
|
||||
| prophase | spindle fibers begin to appear around centrioles
🗑
|
||||
| prophase | nuclear membrane begins to disappear
🗑
|
||||
| metaphase | third stage of cell division
🗑
|
||||
| metaphase | spindle fibers attach to centromeres
🗑
|
||||
| metaphase | chromatids line up across the middle of the cell
🗑
|
||||
| anaphase | centromere splits
🗑
|
||||
| anaphase | spindle fibers pull one member of each chromatid to opposite side of cell
🗑
|
||||
| anaphase | fourth stage of cell division
🗑
|
||||
| telophase | fifth phase of cell division
🗑
|
||||
| telophase | each chromosome begins to uncoil and become less visible
🗑
|
||||
| telophase | nuclear membrane reforms ---nucleus becomes visible
🗑
|
||||
| cytokinesis | process during which the cytoplasm divides producing two separate 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.
