1 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

2 includes is divided into Cell Cycle M phase (Mitosis) Interphase G 1 phaseS phaseProphaseG 2 phaseMetaphaseTelophaseAnaphase Go to Section:

3

4 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?

5

6 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

7 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

8 Centrioles Chromatin Interphase Nuclear envelope Cytokinesis Nuclear envelope reforming Telophase Anaphase Individual chromosomes Metaphase Centriole Spindle Centriole Chromosomes (paired chromatids) Prophase Centromere Spindle forming Mitosis and Cytokinesis Go to Section:

The cell cycle Mitosis is only one section of the life cycle of a cell. Interphase is the main part of the cell cycle. This is where DNA is replicated.

Limits to Cell Growth Why do cells divide rather than continuing to grow indefinitely?  The larger a cell becomes, the more demands the cell places on.

Cell Cycle. Why do cells divide? Growth --by adding cells, not having them get bigger --cells are not efficient for exchanging materials if they are too.

Mitosis Cells must divide in order to create new cells. This is more complicated in eukaryotic cells because there are so many organelles. Bacteria can.
