1 Cell Division page 95 Define Cell Cycle--- the regular sequence of growth and divisionhappens again and again---cycleallows you to grow and repair your bodyduring the cell cycle the cell grows, preparefor division and divides into 2 new cellsWhat are the new cells called after cell division?Daughter CellsSorry guys---NO SON CELLSList the 3 main stages of the Cell CycleInterphase ---Mitosis ---CytokinesisWhat happens during Interphase?Cell Grows---grows to full size,produces structures It needsCell makes exact copy of DNA in its nucleus---each new cell must have a complete set of DNAto survive.
2 What is replication?the process in which the cell makes an exactcopy of the DNA in its nucleusWhat are the 4 phases of mitosis. Explain whathappens in each phase.Mitosis: AnimalPlant cell mitosis | Flash simulation, Animation, Illustration, Picture, Diagram - eduMedia
3 Chromosomes----draw one and explain its function. Double rod structure that has two identical strands of DNA held together by a centromere. Gene with DNA found here.--made of many genes joined together like beads on a string--humans have approximately 35,000 genesWhat is cytokinesis?Final step in the cell cycle.Cytoplasm divides---organelles evenly distributed---two new daughter cells form---identical to parentSingle DuplicatedChromatid Connected by centromere
4 Draw cytokenesis in plant and animal cells. Tell how it is different.In animals cytoplasm pinches together in middle and pulls apart forming two identical cellsIn plants the cell wall cannot squeeze--- a cell plate forms across the middle of the cell separating the genetic material and organelles---new cell membrane forms---new cell wall formsWhat type of reproduction is mitosis?ASEXUALHow is this different from sexual reproduction?One Parent---AsexualTwo Parents---Sexual
5 How many chromosomes are in your body or somatic cells? 23 pairs or 46 chromosomesCells with pairs of chromosomes are calledDiploidCells that do no have pairs of chromosomes areHaploid cells.Haploid cells are called SEX cells(Gametes)Name the haploid cells in your body.Sperm or EggMutation:Change in a gene or chromosomeWhich type of reproduction passes on identical genetic materials?Asexual ReproductionWhich type of reproduction scrambles the genetic materials?Sexual Reproduction
