Cell cycle and cell division
Слайды и текст этой презентации
Слайд 7The cell cycle and cell division
key concept
Through the cell cycle
organisms grow , develop, replace old or damaged cell and
produce new cellsBefore mitosis begin there inphase known as interphase
Interphase is longest part of cell cycle
Interphase gets the cell ready to divide
Слайд 8What is mitosis
Mitosis: cell division involving in somatic cells
Involves only diploid cell
Form of asexual reproduction for some life
+bacteria, protista, fungai)End results: two genetical identical daughter cells
Слайд 11Prophase
Nucleus start to disappear
Chromatin coils become chromosomes
Centrioles appear and begin
to move to opposite end of cells
Spindle fibers form between
the pole
Слайд 13Metaphase
Second stage of cell division
Between prophase and anaphase
Chromosomes become attached
to the spindle fibers
Слайд 15Anaphase
Chromosomes breaks at centromeres and sister chromatids moves to the
opposite end of the cell
Слайд 17Telophase
Final phase of cell division
Between anaphase and interphase
Chromatids or chromosomes
move to opposite end of the cell
Two nuclei are formed
