Ch 10 Cell Cycle and Mitosis
Why don’t you ever see a huge cell like the blob?
What are the advantages of small cell? Think of nutrient movement.
Today’s objective: Cell Cycle Mitosis and cytokinesis
includes
is divided into is divided into
Cell Cycle
M phase (Mitosis)
Interphase
G1 phase S phase ProphaseG2 phase Metaphase TelophaseAnaphase
Go to Section:
What can limit cell growth?
Think about what can limit your growth Hmmm….think about an ant, a tennis ball,
and a basketball Space
Surface/volume ratio
What could happen if cells continue to grow without any limits?
Cell Division
The cell needs to divide to efficiently: Move nutrients Move waste Communicate
Process of cell division Mitosis
Division of DNA and nucleus Cytokinesis
Division of cytoplasm
Mitosis Vocabulary
Chromatin Unwound DNA (looks like string)
Chromosome Wound DNA (typical X shape)
Chromatid Each wing of replicated chromosome Sister chromatids
Centromere Binding site of chromosome for separation
Centrioles
Chromatin
Interphase
Nuclear envelope
Cytokinesis
Nuclear envelope reforming
Telophase
Anaphase
Individual chromosomes
Metaphase
Centriole
Spindle
CentrioleChromosomes
(paired chromatids)
