What is another name for cell reproduction? |
Cell Division |
|
Fill in the blanks When a cell experiences reproduction, or __________ ___________, it produces _______ _____________ _________ that are ____________ ____________ to each other and to the original _________ ________. |
When a cell experiences reproduction it produces two daughter cells that are genetically identical to each other and to the original parent cell. |
|
Before a parent cell splits into two it must _______________________________________ so that it can ______________________________. |
Duplicate its chromosomes so that it can distribute one set of DNA to each of its daughter cells. |
|
What is a chromosome? |
The main gene carrying structure of a prokaryotic cell. |
|
Ordinary cell division produces two daughter cells that are genetically identical. Name the three functions of this type of cell division. |
Cell Replacement Growth of an organism Asexual reproduction of an organism |
|
What is asexual reproduction? |
The creation of genetically identical offspring by a single parent without the participation of gametes. |
|
The type of cellular division that is responsible for asexual reproduction and the growth and maintenance of multi cellular organisms is |
Mitosis |
|
What is sexual reproduction? |
The creation of genetically distinct offspring by the fusion of two haploid gametes, forming a diploid zygote. |
|
Name the type of cell division in sexually reproducing organisms that is responsible for |
Growth and maintenance = mitosis Reproduction = meiosis |
|
What is the material chromosomes are made up of? What is this material made up of? |
Chromatin, which is made up of DNA and proteins. |
|
At what point in a cell cycle can you see chromosomes under a light microscope? |
When the cell is dividing. |
|
What feature allows long molecules of DNA to fit into the tiny nucleus? |
DNA is coiled. |
|
Define the cell cycle |
The ordered sequence of events that extends from the time a cell is first formed from a dividing parent cell until its own division into two cells. |
|
In the eukaryotic cell cell cycle the cell spends most of its time in _______________ about ___% to be exact. This is a time where the cell _______________________ such as _____________ and _____________. State two other things that happen during interphase. |
In the eukaryotic cell cell cycle the cell spends most of its time in interphase about 90% to be exact. This is a time where the cell preforms its normal functions within the organism such as growth and and metabolism.
Cell doubles everything in its cytoplasm Cell grows in size |
|
A duplicated chromosome consists of two sister ________ joined together at the ________. |
Chromatids |
|
What is the most important event that takes place during interphase? What stage does this occur in? What does the letter stand for |
Chromosome duplication occuring in the S Phase. S stands for synthesis |
|
During the G2 phase _____________________________________________. |
The cell consists of two identical sister chromatids and the cell is preparing to divide. |
|
The Mitotic M phase includes two stages. _________________ and ____________. It is the part of the cell cycle where _________________ |
Mitosis and cytokenesis |
|
In the eukaryotic cell cycle during mitosis what is happpening. |
the nucleus and all its contents (DUPLICATED CHROMOSOMES) divide and are evenly distributed forming two daughter nuclei. |
|
In the eukaryotic cell cycle during cytokenesis what is happening. |
the cytoplasm is divided in two |
|
What are the two broadest divisions of the cell cycle? What two processes are involved in the actual duplication of the cell? |
Interphase and mitotic m phase. |
|
Describe the series of events that occur during mitosis including the cellular events and structural changes that occur during them. |
1. Chromatin fibres coil, spindle forms, nuclear envelope breaks into pieces. 3. Centromeres line up 4. Sister chromatids seperate 5. Nuclear envelope forms, chromosomes uncoil and spindle dissapears. |
|
Describe the series of events that occur during cytokenesis including the cellular events and structural changes that occur during them.
|
Cleavage furrow pinches the cell in two producing daughter cells. |
