|---|---|---|---|---|---|
| DNA | A chemical that contains information for an organism's growth and functions. Genetic Material
🗑
|
||||
| Cell Cycle | All the changes the cell goes through from one cell division to the next. Mitosis, Interphase, Prophase, Metaphase, Anaphase, Telophase.
🗑
|
||||
| Chromosomes | DNA is wrapped around protiens like thread arouond a spool and compacted into structures.
🗑
|
||||
| Chromatids | One of two identical chromosomal strands into which a chromosome splits longitudinally preparaty to cell division.
🗑
|
||||
| Mitosis | The part of the cell cycle during which the nucleus divides.
🗑
|
||||
| Interphase | The part of the cell cycle during which a cell is not dividing.
🗑
|
||||
| Double Helix | The shape of the DNA.
🗑
|
||||
| Cytokinesis | The division of the parent cell's cytoplasm.
🗑
|
||||
| Centromere | A specialized structure on the chromosome, appearing during cell division as the constricted central region where the two chromatids are held together and form an X shape.
🗑
|
||||
| Binary Fission | The form of asexual reproduction occurring in prokaryotes.
🗑
|
||||
| Regeneration | The process of new tissue growth at these sites. A starfish gets its arms cut off it can grow them back.
🗑
|
||||
| Asexual Reproduction | One organism produces one or more new organisms that are identical to itself and that live independently of it. One parent has one or more organisms that are exactly like it.
🗑
|
||||
| Sexual Reproduction | A type of reproduction in which male and female reproductive cells combine to form offspring with genetic material from both cells.
🗑
|
||||
| Prophase | The first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
🗑
|
||||
| Metaphase | The third stage of cell division, during which chromosomes line up in preparation for separation.
🗑
|
||||
| Anaphase | The fourth stage of cell divison where the chromosomes get pulled apart by the fibers.
🗑
|
||||
| Telophase | The last stage of mitosis where there are two cells conected and are pinching together then divide.
🗑
|
||||
| Centrioles | In an animal cell, a two-part rod-shaped structure with the parts lying at right angles to each other, located in pairs near the nucleus. Important part of cell division.
🗑
|
||||
| Budding | A form of asexual reproduction in which an outgrowth of the parent becomes constricted and eventually separates to form a new individual.
🗑

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.
