chromosomes DNA wrapped around protiens
Interphase The part of the cell cylce during wich a cell is not dividing, growth and develop

Cell cycle The normal sequence of development and division of a cell
Cytokinesis The division of a the parent cell's cytoplasm
Asexual reproduction One organism produces the new organism or organisms that are identical to itself and that live independantly of it.

regeneration The process of new tissue growth at three sites
chromatids a small organelle that divides ekaryotic cells
cetromere Compacted DNA
binary fission the form of asexual reproduction ocurring in prokayotes
sexual reproduction when two organisms produce another organism,unique organism
prophase the step of mitosis when the DNA in the nuecleuses of a cell condenses and becomes visible under a light microscope
metaphase the step of mitosis when the chromosomes line up in the middle of the cell
anaphase the step of mitosis when the chromosomes split, resulting in two seperate identical chromosomes and then are pulled to topposite sides of the cell
