|
Purpose of cell division |
To grow and repair cells |
|
|
Binary fission calculation |
2 tO tHe power of how many times it reproduces |
|
|
Function of nucleus |
Acts as control centre of cell -surrounded by nuclear membrane which lets material pass in and out |
|
|
Function of nucleolus |
Where ribosomes are produced and assembled |
|
|
Chromosomes |
Structure that contains DNA/genetic material Directs activities in cell |
|
|
Function of Rough endoplasmic reticulum |
Transport proteins throughout cell Series of tubes/flattened sacs with ribosomes attached |
|
|
Ribosomes |
Produces protein for cell function Is in cytoplasm |
|
|
Centrioles |
Helps in animal cell division Made of special microtubules |
|
|
Cytoplasm |
Watery fluid containing everything in a cell membrane Nutrients are transported, absorbed and processed (TAP) |
|
|
Order of mitosis |
(I)PMAT |
|
|
Interphase |
Phase of growing and working before Mitosis |
|
|
Prophase |
Sister chromatids form X’s near center Nucleolus no longer visible Spindle fibres form Nuclear membrane breaks down |
|
|
Metaphase |
Sister chromatids form a line across the center by spindle fibres |
|
|
Anaphase |
Sister chromatids are pulled apart to opposite poles by spindle fibres Chromatids turn back into chromosomes |
|
|
Telophase |
Events of prophase reversed Mitosis is complete and cytokinesis starts |
|
|
Difference between multi and unicellular cell division |
Multicellular: produces cells for growth and repair Unicellular: Type of asexual reproduction |
|
|
Vegetative reproduction |
Makes own roots to become a new plant |
|
|
Fragmentation |
Small part of animal breaks off and grows into new organism Involves regeneration |
|
|
Spore Formation |
Reproduces by forming large numbers of spores |
|
|
Effects of staining slides |
Freezes cells in current stage Makes organelles stand out |
|
|
Mutation |
When DNA/genetic code of a cell changes |
|
|
Cancer |
Disease that causes cells to divide uncontrollably |
|
|
Characteristics of cancer cells |
Enlarged nuclei Uses up more nutrients |
|
|
Cell cycle |
Sequence of events from one cell division to another |
|
|
Order of cell cycle |
(CRDG) cell division, rapid cell growth, duplication of chromosomes, growth and prep for cell division |
|
|
Asexual production |
One parent creates offspring that is genetically identical to them |
|
|
Binary fission |
Parent cell goes through cell division to produce 2 genetically identical offspring |
|
|
Budding |
When offspring begins as a small growth/bud on parent |
