1.Mitosis-It is the process were a single cell divides in to two identical cell.

2.The interphase use to be called the resting phase. Interphase is not the resting phase becuase their is lots of metabolic activity.

3. Interphase: Involves really good preparation for the division process.

• Prophase- The condensation of chromosomes the nuclear membrane disappears formation of the spindle apparatus chromosomes attach to spindle fibers.

• Metaphase: Chromosomes attached by spindle fibers align along the midline of a cell.

• Anaphase: The centromere splits and chromatids move apart.

• Telophase: The nuclear membrane reforms around newly divided chromosomes.

• Cytokinesis: The division of cytoplasm, cell membranes, and organelles occur. In plants, a new cell wall forms.

4. Human cells – 46 chromosomes. Beginning of prophase, 23 pair. Daughter cells there are 46 chromosomes or exactly what we began with.

5.Cytokinesis is the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus.

6.Spindle fibers help in the attachment of chromosomes…they attach at the centromere.

7.Centromeres are proteins that attach sister chromatids together.

8.Centromeres are proteins that attach sister chromatids together.

9.Cleavage furrow in animal cells a cleavage furrow in animal cells a cleavage furrow on the outer surface indicates that two cells are forming. Cell plate plant cells form a cell plate that seperated 2 new cells.

10. The diseas that cells overly reproduce is called cancer. Surgery is a treatment for cancer which removes all or part of the cancer. you can also treat cancer by drugs that the doctors give you.Another way is radiation therapy it can damage or destroy cancer and that is three ways that you can destroy cancer.

1) Mitosis is the process by which a cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components.
2) Interphase….it is a period of diverse activities that occur prior to the cell splitting.
3) Prophase, Metaphase, Anaphase and Telephase. Prophase – chromosomes become visible and cell starts breaking down. Metaphase, duplicated chromosomes become aligned in center of the cell. Anaphase – duplicate sets of chromosomes separate and move to opposite ends of the cell. Telophase – cytoplasm divides and and a new nuclear membrane is formed
4) Human cells – 46 chromosomes. Beginning of prophase, 23 pair. Daughter cells there are 46 chromosomes or exactly what we began with.
5) The process by which a cell divides into two daughter cells.
6) Spindle fibers help in the attachment of chromosomes…they attach at the centromere.
7) Structure in a chromosome that holds together the two chromatids. It is the point of attachment to the structure that pulls the chromatids to opposite ends of the cell during cell division (see mitosis). During the middle stage of mitosis, the centromere duplicates and the chromatid pair separates, each chromatid becoming a separate chromosome. Thus, when the cell divides, both daughter cells have complete sets of chromosomes.
DNA
9) Cleavage furrow is the indentation that begins the process of cleavage, by which animals undergo cytokinesis.A cell plate is a partition formed during cell division in plants that separates the two daughter cells.
10) Cancer is when cells go crazy and over reproduce….chemo-therapy, radiation, surgery are the common types of treatment.

1a type of cell division that results in two daughter cells each having the same number and kind of chromosome as the parents nuclies

2 interphase. but the cell is not resting because its growing and copieing its organelles

3 interphase-the resting phase between succesive mitotic divisions of cells

prophase-the chromosomes become visible and the nuclier membrane starts to brek down

metaphase- chromsomes become attachied to the spindle fibers

anaphase-chromosomes move away from each other to opposite of the spindle

telophase-chromosones move away from the cell and two nuclei are formed

4 Their are 46 chromosomes in the human body 23 in the biggining and 46 in daughter cell

5 the cytoplasmic division of a cell at the end of mitosis bringing about the seperation into two daughter cells

6 One of a network of achromatic filaments that extend inward from the poles of a dividing cell, forming a spindle-shaped figure

7 the point on a chromosome by which it is attached to a spindle fiber during cell division

1. Mitosis occurs in eukaryotic cells, it is a process of cell division that forms two new nuclei.
2. the resting phase of the cell cycle called Interphase. This stage is really not resting it is actually the phase where chromosomes are copied.
3. The stages of Mitosis
~Prophase-when mitosis begins, the nuclear membrane dissolve and chromosomes condense into rodlike structures.
~Metaphase-Chromosomes line up along the equator of the cell. Homologous chromosomes pair up.
~Anaphase-the chromatids separate and move to opposite sides of the cell.
~Telophase-a nuclear membrane forms around each set of chromosomes, the chromosomes unwind.
4. 46 chromosomes are in human body cells. There are 46 chromosomes in the beginning of Prophase. There will be 46 chromosomes in the two daughter cells once the cells divide.
5. Cytokinesis is when the cell pinches in two.
6. The purpose of spindle fibers is to move the chromosomes to the center of the cell during Metaphase, and across the cell during Anaphase. They are attached to the chromosome so they can move them across the cell.
7. The purpose of the centromere is to keep the sister chromatids together.
8. Centromere is found on the chromosomes or chromatids.
9. The difference between a cleavage furrow and a cell plate are in animal cells, a cleavage furrow on the outer surface indicates that two new cells are forming. A cell plate is a plant cell that separates the two new cells.
10. A disease when cells overly reproduce is Cancer. A treatments for this disease is radiation.

1.Mitosis- in eukaryotic cells, a process of cell division that forms two nuclei, each of which has the same number of chromosomes.
2. Interphase, interphase is not resting because it is copying cromosomes.
3. Interphase-before mitosis begins, chromosomes are copied. Each chromosome is then two chromatids.Prophase-mitosis begins, the nuclear membrane dissolves, chromosomes condense into rodlike structures.Metaphase, the chromosomes line up along the equator of the cell, homologous chromosomes pair up.Anaphase, the chromatids seperate and move to opposite sides of the cell.Telophase, a nuclear membrane forms around each set of cromosomes, and the chromosomes unwind, mitosis is complete.
4. 46, there are 23 pairs of chromosomes in the prophase.Forty six pairs of chromosomes.
5. Cytokininesis,in cells that lack a cell wall, the cell pinches in two, in cells that have a cell wall, a cell plate forms between the two new cells.
6. The spindle fibers are responsible for moving the chromosomes to the center of the cell during Metaphase, and across the cell during Anaphase.Some attach to one kinetochore of a dyad, some bind to the arms of the chromosomes.
7.Centromeres are proteins that attach sister chromatids together.
8.Centromeres, spindle fibers and other protein and dna.
9.The cell plate separates 2 cells while the cleavage furrow shows that 2 cells are forming.
10.Aids,However, new medications not only can slow the progression of the infection, but can also markedly suppress the virus, thereby restoring the body’s immune function and permitting many HIV-infected individuals to lead a normal, disease-free life.

1. mitosis- cell divison in which the nucleus divides into nucei containing the same number of chromosomes.
2. Interphase is the resting phase of mitosis. it is waiting for cellular growth and prparation for M phase.
3.Prophase:Nucular enelope breaks down and forms at opiste sides. Metaphase: Nucular membrabne disapperes completly. Anaphase: paired chrosomes seperate and move to oppisite ends of the cell. Telophase: 2 nucli form.
4.46,23,92
5. cytokinesis is when the cell cytoplasm divides to form 2 new daughter cells.
6. The purpose of the spindle fibers is to pull the cell apart to form the daughter cells. They are attached to the centromere.
7. The purpose of the centromere to connect the 2 chromatids to form a chromosome.
8. A centromere and a chromatid is found on a chromosome.
9. The cell membrane creates a cleavage furrow in animal cells, pinching the original cell into two pieces. New cell walls are constructed at the midline of the original cell in plant cells.
10. The disease is persistent hyperplastic primary vitreous. PHPV is a treatment

1. Mitosis- is the stages in wich the cell divides.

2. Interphase is the resting phase of mitosis. it is waiting for cellular growth and prparation for M phase.

3. In prophase the chromosomes become visible and the nuclear membrane begins to break down, spindle fibers also start extending from both poles of the cell. In metaphase the duplicated chromosomes become aligned in the center of the cell. In Anaphase is the stage of mitosis in which the duplicated sets of chromosomes separate and two identical groups move to opposite poles of the cell. in telophase when a nuclear membrane is formed around each new group of chromosomes and the cytoplasm divides

4. Human body cells have 46 chromosomes. There are 23 pairs of chromosomes in the beginning of prophase. There will be 46 chromosomes in the daughter cells.

5. cytokinesis is when the cell cytoplasm divides to form 2 new daughter cells.

1. mitosis- cell divison in which the nucleus divides into nucei containing the same number of chromosomes.
2. The interphase used to be called the resting phase. Interphase isn’t the resting phase becuase their is lots of metabolic activity.
3. Phrophase- chromatin condneses into chromosomes which are in pairs, centrioles start to split apart & move towards separate poles & nuclear eveolope dissolves. Spindle fibers begin forming.
Metaphase- the chromosome pairs line up at the center of the cell & spindle fibers attach. This pulls the chromosomes, now split apart called the sister chromatids.
Anaphase- Spindle fibers pull the sister chromatids apart. The sister chromatids start to move towards the poles.
Telophase- the sister chromatids reach the poles. A nuclear envolop forms around them. Two cells form. Then cytokinesis occurs.
4. Their are 46 chromosomes in the human body cells. Their are 23 chromosomes in the begging of the prophase. Their are four chromosomes in the daughter cells.
5. Cytokinesis is the process when in which a eukatoytic cell seperates the chromosomes in its cell nucleus, into two identical daughter nuclei. Cytokinesis happend at the end of the cycle.
6. A chrosome is an organized structure of DNA & protein. It is a single peice of coiled DNA containing many genes regulator elements. A chromatid one amond the two identical copies of DNA making up a replicated chromosome, which are joined at their centromeres for the process of cell divison.
7. Centromeres are that attach sister chromatids. They are usually located in the center of middle of the chromatids.
8. Spindle fibers are responsible for moving chromosomes to the center of the cell during metaphase & across the cell during Anaphase. Their attached & centromeres of chromosomes.
9. Cleavage furrow in animal cells, a cleavage furrow in animal cells, a cleavage furrow on the outer surface indicates that two cells are forming. Cell plate: plant cells form a cell plate that seperated 2 new cells.
10. Cancer is when cells overly reproduce. Some treatments for cancer are chemotherapy,radiation,therapy, & clinciccal trails.
