3. Give the meaning of the following
terminologies :
1. Diploid
2. Haploid
3. Homologous Pair
4. Chromatid
5. Mitotic Spindle
6. Centromere

4. Two complete
sets of
chromosomes

5. One complete set
of chromosomes

7. Matching pairs
of chromosomes
in a diploid cell

8. Half of a
chromosome

12. “Spindle fiber”
A system of microtubules
that both guide and pull
products of chromosome
replication

13. A region of DNA that is
responsible for the
movement of the replicated
chromosomes into the two
daughter cells during mitosis
and meiosis.

15. 1. What is cell cycle?
2. What is mitosis?
3. What are the different stages of mitosis?
4. What are the different phases of the cell
cycle?
5. What is the longest phase of the cell
cycle?

17. Repeating sequence of
events in a eukaryotic cell
between one cell division
and the next

18. It consists of two distinct
phases: Interphase and
Mitotic phase

19. Period when the cell is not
undergoing division.
The cell perform its regular
functions during this phase.

20. G1 PHASE.
First step of interphase. The time
when cells increase in size in
preparation to cell division.

21. G0 PHASE or Quiescent Stage.
Resting state of the cell
Ex. Nerve and heart cells

22. S PHASE.
Very crucial part of the
interphase because this is the
time when DNA is synthesized.

23. G2 PHASE.
Occurs prior to mitosis. The time
when cell synthesizes proteins
and continues to increase in size.

24. The Mitotic Phase.
Shortest of the stages and is
composed of two tightly-related
processes

25. Karyokinesis.
The division of the nuclear
materials

26. Cytokinesis.
The division of the
cytoplasm

27. Prepared by:
Ms. Jasmine Nikki M. Versoza

28. Growth. Tissue Repair.
Sexual Reproduction

29. The type of cell division
taking place in somatic
cells. It results in diploid
chromosome number.

30. Prepared by:
Ms. Jasmine Nikki M. Versoza

41. Why do red blood cells do
not replicate?
Because it is the bone
marrow’s job to produce blood
cells

42. Why don't you hear about
people getting heart cancer?
Because heart muscle cells
(myocytes) are not always
dividing

43. How do cells die?
Two ways a cell can die:
Necrosis and Apoptosis

44. NECROSIS
Happens when a cell is
damaged by external factors
such as poison or injury

45. APOPTOSIS
Happens when cells
commit suicide
