Growth : make an organism larger and more complex
Development : cell differentiation
Decrease : small size cells Repair : tissues that were
damaged Replace : lost/ broken down cells Reproduce : to make more cells
or organisms

How many chromosomes in one nucleus?
http://ib.bioninja.com.au/_Media/diploid-number_med.jpeg
Most are diploid (2n) but some are not.

Please draw 3 cells in your paper, First one is monoploid (n = 4), another one is diploid (2n =8),
the last one is tetraploid (4n =8).
?
Eukaryotic cell has many linear chromosomes, so, the karyokinesis of eukaryote is quite different from prokaryote.

- Chromatin condenses into chromosome (chromosome packing) - Nucleolus disappear - Separation of centrosome - Formation of the mitotic spindle

Chromosomes line up along metaphase plate or equatorial plate (imaginary plane) At late metaphase, centromere divides, preparing to separate chromatids

Metaphase
Chromosomes break at centromeres, and daughter chromosomes (1csister chromatids) move to opposite ends of the cell.

- Nuclear membrane reforms, nucleoli reappear, chromosome unwind into chromatin - Myosin II and actin filament ring contact to cleavage cell in two.
