Term
| During interphase, a cell: |
|
Definition
Performs its normal functions
Doubles everything in its cytoplasm

|
Term
| chromosomes duplication, when the DNA in the nuclaus is precisely doubled, this occurs in the middle of interphase called: |

Definition
| S phase from DNA synthsis |
|
|
Term
| the interphase periods before and after the S phase are called |

Definition
| part of the cell cycle when the cell is actually dividing |
|
|
Term
| mitotic (M) phasethe includes two overlapping processes: |
|
Definition
Mitosis, in which the nucleus and its contents divide evenly into two daughter nuclei
Cytokinesis, in which the cytoplasm is divided in two |

Term
| Mitosis consists of four distinct phases: |
|
Definition
(A) Prophase
(B) Metaphase

Term
|
Definition
| an indentation at the equator of the cell. |
|
|
Term
| a ring of microfilaments in the ___________ just under the plasma membrane contracts, like the pulling of a drawstring, deeping the furrow and pinching the parent cell in two |

Term
| cytokinesis in plant cell occurs differently. membranous vesicles containing cell wall material collect at the _________ of the cell. |

Definition
|
|
Term
| the vesicles gradually fuse, forming a membranouse disk called the ___________-- |
|
Definition

|
Term
|
Definition
| outward, accumulatng more cell wall material as more vesicles joint in. |
|
|
Term
| eventually , the membrane of the cell plate fuses with the plasma membrane and the cell plate's contents join the parental cell wall. the results is the ___________. |
