Cell Division Flashcards
Why does cell division happen
to
Repair
Reproduce
True of false
Cells shouldn’t be identical in cell division
False
Physical location of DNA
Chromosomes
How long is cell cycle
24 hrs
2 types of cell division
Mitosis, and Meiosis
Longer phase
Preparation for Cell Division
Interphase
Shorter phase
Actual cell division
Mitotic phase / Mitosis
What are the phases in interphase (in order)
G1
Synthesis
G2
Phases in Mitosis
PMAT
Prophase
Metaphase
Anaphase
Telophase
How do chromosomes form
Because when the chromatin condenses it creates chromosomes
Difference of chromatin and chromatid
Chromatin is the particle before it condenses to make chromosomes
Chromatid is the ‘butterfly wings’ of a chromosome (there are 2 each chromosome)
In ____ phase
Phase immediately after the cell division
Prepares to replicate DNA
For cell’s increase in size
Cell organelles double
G1 phase
____ phase
When DNA is replicated
Single to double strand chromosome
S phase
____ phase
Final preparation for cell division
Increase in size
G2 phase
___ phase
State of cellular arrest
Will not prepare to undergo cell division
G0 phase
Also called duplication division
Mitosis
Importance of Mitosis (2)
-growth of organism
-Tissue repair
What can Mitosis produce
Diploid cells
PMAT
——phase
Chromosomes condense
Nuclear membrane disappears
Prophase
PMAT
—-phase
Longest phase in mitosis
Chromosomes line up in the middle of the cell
Metaphase
PMAT
—-phase
Chromosomes move away from each-other and become single strand chromosomes
Anaphase
PMAT
—-phase
Nuclear membrane reappears
In animal cell
Cleavage furrow deepens
In plant cell
Cell plate grows
Telophase
Happens during Telophase
Process of cell splitting into 2
Cytokinesis
What happens after Mitosis
2 new identical cells
Change from double to single strand to chromosome
