Can you explain what happens during cytokinesis?
The parent cell's cytoplasm and organelles are evenly divided between two new daughter cells, plus all this other stuff.
Can you name this stage of the cell cycle?
Prophase
As chromosomes become more visible at the beginning of mitosis, what disappears?
The nuclear membrane and nucleuolus both disappear.
Can you name this stage of the cell cycle?
Metaphase
In plant cells, cytokinesis occurs when _______________________.
a new cell wall forms between the newly formed daughter cells
Can you name this stage of the cell cycle?
Interphase
Can you name this stage of the cell cycle?
Telophase
At the beginning of mitosis (Interphase, Prophase, Metaphase) a chromosome consists of two _________________.
sister chromatids
What is the phase of the cell cycle when "hot dog" shaped chromosomes first become visible and the centriols migrate to opposite ends of the cell?
Prophase
True or False: Cytokinesis is different between plant and animal cells.
True. Plant cells need to make a new cell wall between them while animals cells don't.
TERMS of ATTACHMENT! Can you explain how spindle fibers, centromeres, and kinetochores attach and work together?
Centromeres attach chromatids together while spindle fibers attach to kinetochores.
What is the difference between diploid cells and haploid cells?
Diploid cells have ALL of the chromosomes needed by the organism. Haploid cells have HALF the chromosomes needed by the organism.
How many chromatids will a duplicated chromosome have?
A duplicated chromosome should have two chromatids.
What does mitosis do for plants, animals, and people?
Mitosis results in growth, developement, and wound healing.
In which stage of the cell cycle do eukaryotic cells often spend about 90% of their time.
Interphase
How is DNA arranged during Interphase?
The intact nucleus is filled with loose, extended homologous chromosomes that are piled on top of each other as chromatin.
Can you name this stage of the cell cycle?
Anaphase
What are homologous chromosomes?
Homologous chromosomes are "twin" chromosomes. They are the same size and contain the same genetic information. One comes from Mom, the other from Dad.
Spindle fibers are created by tiny organelles called _______________.
centrioles
In order to prepare for cell division, DNA becomes more compact by ______________.
wrapping tightly around histone proteins
After mitosis is complete, will the resulting daughter cells be diploid or haploid?
Mitosis should result in the daughter cells having the exact same number of chromosomes as their parent cell. Thus, they are diploid.
