The document discusses the cell cycle, which consists of interphase and mitosis followed by cytokinesis. Interphase includes the G1, S, and G2 phases where the cell grows and duplicates its DNA. Mitosis is divided into prophase, metaphase, anaphase and telophase where the cell nucleus and chromosomes divide. Cytokinesis then separates the cytoplasmic contents into two daughter cells completing the cell cycle. The cycle allows cells to grow and divide to form more cells.

2. To grow up does this mean the cell
increase in size or increase in number?

3. Cells have distinct phases of growth, reproduction,
and normal functions.

4. What do you do after you exercise??

5. Can you create a mind map for the cell
cycle?

6. The Cell Cycle
• Once a cell reaches its size limit it must either stop growing or divide.
• Cells reproduce by a cycle of growing and dividing called the cell cycle.
• Each time a cell goes through one complete cycle, it becomes two cells.

7. What if the cell continue to divide?

9. A.___________: stage during which the cells
grows, carries out cellular functions, and
replicates its DNA.
B.__________________: the cell’s nucleus
and nuclear material divide; has four
substages.
C.___________________________: cell’s
cytoplasm divides, creating two new cells.
Match : Cytokinesis – Mitosis- Interphase

10. • Interphase: stage during which the cells
grows, carries out cellular functions, and
replicates its DNA.
• Mitosis: the cell’s nucleus and nuclear
material divide; has four substages.
• Cytokinesis: cell’s cytoplasm divides, creating
two new cells.

11. The stages of interphase
• Interphase has three substages: G1, S, and G2 .
• __________, the cell is growing and carrying out normal cellular
functions.
• _________the cell copies its DNA in preparation for cell division
• ______________follows the S stage and is the period when the cell
prepares for the division of its nucleus.
.

12. The stages of interphase
• Interphase has three substages: G1, S, and G2 .
• During G1,
• the cell is growing and carrying out normal cellular functions. ,
the cell increases in mass and organelle number in preparation for
cell division
• During S, the cell copies its DNA in preparation for cell division
• The G2 stage follows the S stage and is the period when the
cell prepares for the division of its nucleus. The cell synthesizes
additional proteins and continues to increase in size.

13. The Cell Cycle
Mitosis and cytokinesis
• During mitosis, a cell’s nuclear material divides and separates into opposite
sides of the cell.
• During cytokinesis, the cell divides into two daughter cells.

18. Observe and answer:
1. How many phase you can observe?
2. In which phase the chromosomes are aligned in the equator
of the cell?
3. In which phase the chromatin material condenses to specify
into single chromosomes?
4. In which phase the nuclear membrane appear again in the
daughter cells?
5. In which phase the nucleus is totally divided into two
identical nucleoli?

3. nuclear membrane disappears
4. spindle forms

20. 1. chromosomes line up on the equator of the cell
2. spindles attach to centromeres
Equator

25. -Occurs at end of Mitosis
--division of the cytoplasm to form 2 new daughter
cells
--organelles are divided
-Daughter cells are genetically identical
