|---|---|---|---|---|---|
| asexual reproduction | reproduction that requires only one parent and produces offspring that are genetic copies of the parent
🗑
|
||||
| binary fission | a form of asexual reproduction in which a single parent cell replicates its genetic material and divides into two equal parts
🗑
|
||||
| budding | a form of asexual reproduction in which areas of an individual may undergo repeated mitosis and cell division and can develop into an identical organism
🗑
|
||||
| cancer | the result of uncontrolled cell division
🗑
|
||||
| cell cycle | the three stages of the life of a cell, including the sun, the moon, planets and the stars
🗑
|
||||
| clone | an identical genetic copy of an organism's parent
🗑
|
||||
| cytokinesis | the final stages of the cell cycle, which separates the two nuclei and cell contents into two daughter cells
🗑
|
||||
| fragmentation | a form of asexual reproduction in which each fragment of an organism develops into a clone of its parent
🗑
|
||||
| interphase | the first and longest stage of the cell cycle, in which cells carry out life functions and cells that divide prepare for cell division
🗑
|
||||
| mitosis | the second, and shortest stage of the cell cycle; the process in which the duplicated contents of the cells nucleus divides into two equal parts
🗑
|
||||
| replication | the process during which the cell copies 3 billion base pairs of DNA information it the nucleus
🗑
|
||||
| spindle fibres | tiny tube-like structures made of protein to which chromosomes attach during cell division
🗑
|
||||
| spore | reproductive cells that grow into new individuals by mitosis
🗑
|
||||
| stem cell | cells that have the potential to become many different types of cells; two types of stem cells are embryonic stem cells and adult stem cells
🗑
|
||||
| vegetative reproduction | reproduction in which special cells, usually in plant stem cells and plant roots, divide repeatedly to form structures that will eventually develop into a plant identical to the parent
🗑

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.
