The lesson plan aims to define cell cycle and identify its different stages. It will discuss that cell cycles are generally divided into interphase and mitosis. Interphase consists of G1, S, and G2 phases where the cell grows and prepares for division. Mitosis is then explained in four stages: prophase, metaphase, anaphase, and telophase, where the chromosomes condense, align, separate, and arrive at opposite poles of the dividing cell respectively. The students are expected to understand and identify the stages of the cell cycle.

1. Detailed Lesson Plan in Biology
I. OBJECTIVES
at the end ofthe lesson, the students are expected to:
a. define cell cycle;
b. identify the different stage of cell cycle.

Chalk/Blackboard
III. PROCEDURE
A. Preparation
Teachers Activity
1. Greetings
- good morning class
2. Checking ofattendance
3. Motivation
- Ok class, I have a question, what
comes firstinto your mind if you see
this (draw a circle in the blackboard)?
- correctit’s a cycle
- and how is an organism grow
- yes, very good!
B. Presentation
- Ok class, today I will discuss to you
about cell cycle.
- what comes firstinto your mind if you
heard the word “cell cycle’?
- Yes correct!
- What else?
- correctagain, another?
- yes, very good!all ofyour answers are
correct.
- So all cycle is a continues eventfor
growth of an organism.
- cell cycles are generally divided into
two phases, namely interphase and
mitosis.
- So, in interphase it is G1 or growth 1, S
phase or synthesis phase and G2 or
growth 2 to that the cell will be ready in
division or reproduce again.(use the
visual aids to show the G1 and G2)
- Do you understand class?
Students Activity
- good morning ma’am
- (via monitor)
- circle, infinite, continuous, cycle
- through division ofcell
- cell divides and reproduce
- growth of cell
- in my own understanding when we say
cycle itis one cell will become two
ma’am!

2. - let’s proceed to mitosis
- so, in mitosis it is a continues process
and it can be divided into four different
state,
- what is the first stage?
- ok. in this phrase where visible thread
are formed with the condensation ofthe
chromosomes.
- this phase, two strand of chromosomes
form, and each one is called chromatid,
the two chromatids are joined at a
region called centromere
- all begins to migrate the opposite sides
of poles ofthe cell
- at the end ofthe prophase, whatcomes
next?
- correct, what is metaphase? the
chromosimes with catromeres attached
to the spindle fibers are somewhat
scattered.
- do you understand class?
- what is the 3rd phase?
- and what is anaphase?
- you have a point
- actually anaphase is the shortestperiod
of mitosis, itbegins with the separation
of centromere.
- and lastly the Telophase
- the chromosomes are finally arrive at
the opposite poles ofthe cell.
IV. Generalization.
V. Assignment:
Advance reading in the DNA Replication
- yes ma’am
- prophase ma’am
- metaphase ma’am
- yes ma’am
- Anaphase
- the separation ofthe mother and
daughter cell
