1
Ratio of Surface Area to Volume in Cells
Section 10-1 Cell Size Surface Area (length x width x 6) Volume (length x width x height) Ratio of Surface Area to Volume
2
Figure 10–4 The Cell Cycle Section 10-2 G1 phase M phase S phase
3
INTERPHASE (G1 - S - G2) Can’t see chromosomes
In between divisions Cells are in this phase most of the time Can see nucleus DNA spread out as chromatin Can’t see chromosomes DNA gets copied (S) Cell gets ready to divide
4
PROPHASE 1st dividing phase DNA scrunches into chromosomes
Pearson Education Inc publishing as Pearson Prentice Hall PROPHASE 1st dividing phase DNA scrunches into chromosomes Centrioles appear in centrosome region & move to poles Nuclear membrane & nucleolus disappear Spindle fibers form & attach to chromosomes
5
________ region organizes spindle
CENTROSOME Spindle MICROTUBULES are part of cytoskeleton
6
METAPHASE Chromosomes line up in ___________ middle
Images from: Pearson Eduction Ince; Publishing as Pearson Prentice Hall
7
ANAPHASE Centromeres split Centrioles pull chromatids_______ apart
Images from: Pearson Eduction Ince; Publishing as Pearson Prentice Hall
8
two TELOPHASE (reverse prophase steps) See ______ nuclei
Nuclear membrane & nucleolus return Chromosomes spread out as chromatin Centrioles disappear Spindle fibers disappear Images from: Pearson Eduction Ince; Publishing as Pearson Prentice Hall
9
CYTOKINESIS Cytoplasm splits into 2 cells CLEAVAGE FURROW
ANIMAL CELLS pinch cytoplasm in two with a ______________________ CLEAVAGE FURROW
10
CYTOKINESIS Cytoplasm splits into 2 cells
PLANT CELLS can’t pinch because they have a sturdy ____________ Plant cells separate cytoplasm by growing a _______________ down the middle. CELL WALL CELL PLATE
