B. Reviewing Previous Lesson or
presenting the new lesson
(Elicit)
Now, let’s review our previous lesson.
Who among you remember our previous lesson? Anyone?

4. (3 minutes) Now, what is a chromosome?
Very good! So, what are the parts of the chromosomes?
Now, what are the types of chromosomes?
How many chromosomes does human have?
What chromosomes does female have?
How about the Male?
Very good! I am grateful that all of you really understand
our previous topic.
Our previous lesson was all about the
chromosomes.
Chromosomes were first discovered by
Strasburger in 1815 and the term
“chromosome” was first used by Waldeyer
in 1888. Chromosomes are threadlike
structures present in the nucleus. They are
important because they contain the basic
genetic material DNA. These are present
inside the nucleus of plants as well as
animals (including the human.
Centromere, heterochromatin,
euchromatin, chromatids, p arm and q
arm.
Telocentric, Acrocentric, Submetacentric
and Metacentric.
There are 23 pairs of chromosomes Ma’am
or 46 chromosomes.
2X chromosomes Ma’am.

5. 1X and 1Y Ma’am.

Let us check your answer.
E. Developing mastery (Leads to
Formative Assessment 3)
(Explain)
(10 minutes)
Now, let’s check if you arrived in the correct answer.
1. How many phases are in the cell cycle as shown in the
diagram?
The cell cycle as shown in the diagram is a
four-stage process consisting of gap1,
synthesis, gap 2 and mitosis.

9. 2. Starting at the started cells, what is the order of the
stages of a cell’s life? Define each stage concisely.
3. What is the purpose of Gap 2 in the cells growth?
Count the number of your correct answers and pass your
paper to the center aisle.
1. Gap 1- the cells grow physically and
copies organelles
2. Synthesis- the cell synthesizes a
complete copy of the DNA in its nucleus
and duplicated the centrosome.
3. Gap 2- the cell grows more, makes
proteins and organelles, begins to
reorganize its contents in preparation for
mitosis.
F. Finding practical applications of
concepts and skills in daily living/
Making generalizations and
abstractions about the lesson
(Elaborate)
(15 minutes)
Discussion of the concept
Have you enjoyed the activity?
Now, let’s discuss our lesson.
What is cell cycle? Anyone?
Exactly! We have two stages of cell cycle, who can give me
the first stage of cell cycle?
How about the second stage of cell cycle? Yes?
Yes, Ma’am
Cell cycle is a series of events that takes
place in a cell as it grows and divides. The
cell cycle is a four-stage process, in which
the cell increases in size, copies its DNA,
prepares to divide and divides.
Interphase Ma’am.
Mitotic phase or Cell Division Ma’am.

10. Now, who can define interphase?
Impressive! How about the Mitotic phase or Cell division?
Precisely! Now, let’s see the diagram of the cell cycle.
Based on the diagram, the cell cycle containing what?
Interphase is the interval between two cell
divisions. During this stage, the cell is not
dividing; it merely grows. The
chromosomes double or replicate itself
because the DNA molecule contained in
the chromosome produces a precise copy
of itself.
Mitotic phase or cell division is the stage at
which actual cell division takes place.

11. Very good! The duration of the cell cycle varies between
organisms and cell type. The human cell cycle takes 24
hours on average.
Once again, based on the diagram, what are the sub-stages
of interphase?
Now, what is First gap period or G1?
Precisely! How about the Synthesis period or S phase?
Cell growth, DNA replication and cell
division.
First gap period or G1, Synthesis period or
S phase, Second gap period or G2.
First gap period or G1 is where cells grow
continuously and prepare for DNA
replication. During this phase, cells are
metabolically active and copy essential
organelles and biochemical molecules
such as proteins.
Synthesis period or S phase is takes up the
responsibility of duplication of DNA from
2N to 4N and centrosome that we found in
the inside the cell. This centrosome
contained centrioles that are important for
the cell division.

12. Exactly! How about the Second gap period or G2?
Let’s take a look at the picture. This picture shows the cell
in the interphase period.
What does the yellow bar represent?
How about the outline of the big circle?
How about the small orange circle?
How about the dark blue circle?
Second gap period or G2 where the cell
grows more in size and rapidly. The cells
make more proteins and organelles. The
most abundance function of this phase is
prepares the cells for actual cell division or
mitosis.
Centriole Ma’am.
Cell membrane Ma’am.
Nucleolus Ma’am.
Nucleus Ma’am.

13. What do you call to the green shade of the big circle?
How about the outline of the dark blue circle?
How about the root-like in the dark blue circle?
Impressive! Do you have any questions or clarifications?
Application

(Answers may vary)

15. Now, what is the importance of cell cycle in our daily
living?
Generalization
To sum up our lesson today, I have some questions for
you.
What is cell cycle?
What are the two stages of cell cycle?
What is interphase?
Growth and Development: The cell cycle is
responsible for the growth and development of
organisms. Through cell division, new cells are
produced, allowing for the growth of tissues
and organs
Cell cycle is a series of events that takes
place in a cell as it grows and divides. The
cell cycle is a four-stage process, in which
the cell increases in size, copies its DNA,
prepares to divide and divides.
Interphase and mitotic phase or cell
division Ma’am.
Interphase is the interval between two cell
divisions. During this stage, the cell is not
dividing; it merely grows. The
chromosomes double or replicate itself
because the DNA molecule contained in
the chromosome produces a precise copy
of itself.

16. How about the Mitotic phase or cell division?
What are the sub-stages of interphase?
Now, what is First gap period or G1?
Precisely! How about the Synthesis period or S phase?
Exactly! How about the Second gap period or G2?
Mitotic phase or cell division is the stage at
which actual cell division takes place.
First gap period or G1, Synthesis period or
S phase, Second gap period or G2.
First gap period or G1 is where cells grow
continuously and prepare for DNA
replication. During this phase, cells are
metabolically active and copy essential
organelles and biochemical molecules
such as proteins.
Synthesis period or S phase is takes up the
responsibility of duplication of DNA from
2N to 4N and centrosome that we found in
the inside the cell. This centrosome
contained centrioles that are important for
the cell division.
Second gap period or G2 where the cell
grows more in size and rapidly. The cells
make more proteins and organelles. The
most abundance function of this phase is
prepares the cells for actual cell division or
mitosis.
