-
What is the division of nucleus?
Mitosis
-
What is the divison of cytoplasmic structures and cytoplasm?
cytokinesis
-
What do cells do in the G1 phase?
the cells grow in size
-
What is uncoiled chromatin?
chromatids
-
What phase in cell growth duplicates its chromosomes and other cell material?
S phase
-
Before what synthesis does the cells' chromosomes consist of one chromatid in the S phase?
DNA Synthesis
-
What happens after DNA Synthesis in the S Phase?
the cell's chromosomes consist of 2 identical chromatids attached at a centromere.
-
In what phase do the cell prepares the enzymes and metabolic activities for mitosis?
G2 Phase
-
What is interphase considered not to be?
not a phase of mitosis
-
Is DNA present in interphase?
yes.
-
What parts of the nucleus is present or seen as visible in Interphase?
Nucleolus and nuclear membrane.
-
When does chromatin officially start replicating?
Interphase
-
What are the Phases of Mitosis?
- PMAT
- Prophase, Metaphase, Anaphase, & Telophase.
-
What do animal cells have in prophase?
visible asters and non-visible centrioles
-
What about the nucleus happens in Prophase?
Nuclear membrane is not distinct. and nucleolus disappears
-
What does the DNA do in Prophase?
it coils into visible chromosomes.
-
What happens to the chromosomes in Metaphase?
they line up in the center called the equator.
-
What else happens in Metaphase besides the chromosomes lining up in the center?
the spindle fibers are attached to the centromere of each chromosome.
-
What two major things happen in Metaphase?
- the centromeres divide.
- chromosomes move to the opposite side of the poles of the cell.
-
What happens to the chromosomes in Telophase?
uncoil the chromatin.
-
What does the nucleus part of the cell do in Telphase?
Nuclear membrane and nuclioli reappear.
-
Whats distinct about animal cells in late Telophase?
the cell divides with a cleavvage furrow.
-
Whats distinct about plant cells during telophase?
the cells divide with the formation of a cell plate
-
What are daughter cells?
The cells formed after mitosis is complete. They are smaller and identical to the parental cell.
-
What is distinct in plant cell division?
- Chromosomes are large.
- Cell walls are present.
- Cells divide with the cell plate.
-
What does the cell plate signal in plant cells in Telophase?
cytokinesis
