Definition
interphase
mitosis
cytokinesis |
|
|
Term
|
Definition
| the first and longest stage of the cell cycle in which cells carry out life functions and cells that divide prepare for cell division |
|
|
Term
|
Definition
| the second and shortest stage of the cell cycle the process in which the duplicated contents of the cell's nucleus divides into two equal parts |
|
|
Term
|
Definition
| the final stage of the cell cycle which separates the two nuclei and cell contents into two daughter cells |

Definition
*duplicated chromosomes from into an x shape and the nucleolus disappears
*spindle fibres which are tiny tubs-like structures made of protein,begin to form in plant and animals cells |

Term
|
Definition
| the duplicated chromosomes line up across the middle of the cell |
|
|
Term
|
Definition
| the duplicated chromosomes move apart to opposite ends of the cell |
|
|
Term
|
Definition
| a nucleolus forms around the chromosomes at the opposite ends of the dividing cell |

| reproduction that requires only one parent and produces offspring that are genetic copies of the parents |

Term
| advantages of asexual reproduction |
|
Definition
1.large colonies can out compete other organisms for nutrients and water
2.large numbers of offspring reproduce very quickly
3.species can survive if the number of predators increases disadvantage of asexual reproduction include |

Definition
1offspring compete for food and space
2extreme temeratures can wipe out entire colonies
3negative mutations can destroy many offspring |

Term
|
Definition
| a form of asexual reproduction in which a single parents cell replicates its genetic material and divides into two equal parts |
|
|
Term
|
Definition
| a form of asexualrepoduction in which areas of an individual may underge repeated mitosis and cell division and can develop into an identical organism |
|
|
Term
|
Definition
| a form of asexual reproduction in which each fragment of an organism develops into a clone of its parent |
|
|
Term
|
Definition
| a spore is a reproductive cells the grows into a new individual by mitosis.spores are very light in weight and spore producers rely on water or wind to carry the spores away |
|
|
Term
|
Definition
| reproduction in which special cells usually in plants stems and plant roots divide repeatedly to form structures that will eventually develop into a plant identical to the parent |
