Teacher Activity
B. Motivation
Good afternoon class! How are you this day?
Okay, since you are fine, I guess you are ready for
our class this afternoon. I have here some pictures
and as I flashes it before you, I would like you to
give me the function of it. Okay?
(Shows a picture of a door)
(Shows a picture of a wall)
(Shows a picture of fridge)
(Shows a picture of floor, tables and chairs)
(Shows a picture of waiter and waitress)
(Shows a picture of a take-out box)
(Shows a picture of a chef)
(Shows a picture of line-up cooks)
(Shows a picture of a janitor)
Okay, where can we find them?
These pictures, the chefs, the waiters and waitresses,
the refrigerator, the take-out box, the door, the wall,
is what comprises the restaurant. This is their basic
structural and functional unit.
Same with the eukaryotes, we also have our basic
structural and functional unit. Can someone tell me
what is it?
Student Activity
We’re fine ma’am!
Yes ma’am!
It lets people in and out of the room!
It protects what is inside the room ma’am!
It stores food!
It caters all the people around it ma’am!
They serve as the organizer ma’am by serving food!
Packages the food that the costumer wants to take out
ma’am!
That’s the chef, it cooks food!
That’s still a chef but they are many, they convert the
ingredients to a ready to eat food!
That’s a janitor, it cleans the establishment ma’am!
At a restaurant ma’am!
The cell ma’am!
That’s right! And today, we are going to tackle about
the plant and animal cell.
C. Lesson Proper.
Before we start our lesson, we are going to have an
activity. Are you ready class?
Count of from 1 to 3.
(Gives the materials for the activity) the title of our
activity is comparing plant and animal cell.
Okay, can someone read the objectives for your
activity?
Yes ma’am!
Jecca, please read the directions.
Compare plant and animal cell below. Draw a Venn
diagram to show the similarities and differences of
the two cells. Write your answers on the manila
paper and post it in the board. Late answers will be
deducted from their gained points (according to the
(the students form their groups)
Objectives: After doing this activity, you should be
able to
 Identify parts of the cell;
 Describe plant and animal cell;
 Differentiate plant cells from animal cells;
 Construct a Venn diagram to show parts that
are common to both and parts that are only
found in either plant or animal cells.
correct answers given). Choose a representative to
report your groups’ work.
Are the directions clear? Is there any questions?
No ma’am!
This activity is good for 5 minutes, it is important
that each member will cooperate. Okay? You may
start now.
(After 5 minutes)
(students answer their activity)
Okay, let’s check if your answers were correct. Just
like a restaurant, a cell also has many components or
parts in order for them to work efficiently. Now, let’s
take a look at this illustration.
(shows a picture of animal cell)
What have you observed in the illustration?
How about this?
(shows a picture of plant cell)
They are composed of many parts ma’am and is
circular in shape.
(students report their works)
They have the same components ma’am but that cell
is rectangular in shape.
Both cells have almost the same parts. Now let’s take
a look at these two cells.
There are three components of a cell, the cytoplasm,
the nucleus and the cell membrane. Let’s look at first
the nucleus. It is found in the center of the cell. Can
someone point out where is the nucleus?
What is the function of the nucleus?
(student points out the nucleus)
Almost all of the activities of the cell is directed by
the nucleus. Now let’s go to the cell membrane, it is
the outer layer of the animal cell, it encloses other
organelles. Can someone points out where the cell
membrane is?
It is also called semipermeable membrane. Why is it
called semipermeable?
(student points out the cell membrane)
What would happen if the cell membrane does not
function properly?
Without plasma membrane, any substances can go in
and out of the cell. The cell may be affected by the
exit of the needed substances or the entrance of
unneeded substances or the poisonous substances that
can lead to death of the cell.
(student points out the cell wall)
It is the control center of the cell ma’am!
It allows specific molecules to pass through and
blocking others.
Okay, now, let’s go to the cell wall. It is found just
outside of the cell membrane. Can someone point out
where is the cell wall?
Can we found this in both cells?
No ma’am, we can only find this on the plant cell.
What is the purpose of cell wall in plants?
Okay, now let’s go to the cytoplasm. It is where the
other organelles are suspended. Can someone point
out where is the cytoplasm?
What is the function of the cytoplasm?
It gives them shape and protection to plant cell
because they are tough or rigid.
(student points out the cytoplasm)
It maintains the osmotic concentration of the cells
and prevents them from shrinking or bursting.
Now mitochondria is one of the organelles that is
found in the cytoplasm, it is an oval shape organelle
and is surrounded by a double membrane. Where is
mitochondria in the cell?
What is the function of mitochondria?
(student points out the mitochondria)
It is the powerhouse of the cell.
Yes, it produces energy that is needed by the body.
How about the endoplasmic reticulum?
What is the function of the endoplasmic reticulum?
It is a large network of tubes and is like maze or
folds.
It carries proteins to different parts of the cell.
There are two types of endoplasmic reticulum, what
are they?
What makes it rough?
The smooth and the rough endoplasmic reticulum.
What is a ribosome then?
Ribosomes are circular in shape and are either free or
attached to the endoplasmic reticulum.
(student points out the ribosomes)
Can someone point out where is the ribosome is?
Okay. This one’s here is the lysosome they break
down the waste products and detoxify the cell.
The Golgi apparatus are like flattened stacks of sacs,
where is the Golgi apparatus in the illustration?
What is the function of Golgi apparatus?
The vacuoles on the other hand are organelles for
storage. It is easily seen in plant cell because they
have large vacuoles. Can someone point out the
vacuoles?
How would vacuoles in plants serve as defense
against animals that eat them??
Chloroplasts is an elongated or disc-shaped
organelle, can someone point out the chloroplast?
Where can we find them?
What is the function of chloroplast?
Okay, chloroplast contains chlorophyll, a green
pigment in plant which absorbs light energy from the
sun and is the site of photosynthesis in plants.
Why are there several chloroplast in the cell?
The ribosomes make it rough.
(student points out the Golgi apparatus)
They function as the packaging unit of the cell, they
sort and modify proteins.
(student point out the vacuoles)
Vacuoles in some plants may contain poison or toxic
substances and these substances may harm animals
once eaten, this serves as their protection.
(student points out the chloroplast)
Chloroplasts can be found only in plant cell.
They are the site of photosynthesis in plants.
It is the site of photosynthesis and the more the
chloroplast in them makes them more efficient for
making food.
This one’s here is the centrosome, it organizes the
cell parts during cell division.
Okay let’s go back to the pictures. Let us connect
Yes ma’am!
their functions to the functions of the organelles. Are
you ready?
In a restaurant, you see its walls. What do these walls It refers to the cell wall ma’am!
represents in the cell?
Yes! That is because both the cell wall and the wall
of the restaurant give the object structure and creates
a barrier from what’s inside to what’s outside.
How about the door of the restaurant? What does it
do?
That’s right! And it resembles to what?
On the other hand, the chef is similar to the nucleus,
why do you think so?
That’s right! The nucleus is the control center of the
cell just like the chef who’s the one in control in the
restaurant on what food to make.
The nucleolus is the same as the chef’s brain, would
you agree?
What do you think relates to the cytoplasm in the
restaurant?
Okay, the cytoplasm relates to the seating area and
the area in the kitchen. A seating area contains all of
the tables, and the kitchen contains all of the food,
cooking tools, and the fridge.
Since we’re talking about fridge, what does the
fridge do?
And it is the same as to what in the restaurant?
How about the janitors? What do they represents?
Line of cooks convert ingredients into meals
convenient for the costumers to eat. What does it
represent to a cell?
Endoplasmic reticulum serves as the pathway of the
restaurant, where the proteins, lipids and other
components are assembled.
How about the take out boxes? What do they
represents?
What is the cytoskeleton for?
In a restaurant, the waiters and waitresses give the
job structure and internal organization. The waiters
and waitresses must be organized.
Again, the difference between the animal and plant
cell is that the shape of the plant cell is fixed and
rectangular while in animal it is round and irregular.
Also, plants have chloroplast, cell and large vacuoles
while animals don’t..
Are there any clarification? Questions?
The door lets the people enters in and out of the
place.
The cell membrane, because it determines what goes
in and out of the cell, the only way for any molecule
to get inside of the cell is through the membrane. Just
like the door is the only way of the restaurant.
The chef is like the nucleus because he/she is the one
in control on what food to make and how to make it.
Yes ma’am, because the chef’s brain contains
valuable recipes needed for creating food.
The chairs and tables’ ma’am and also the floor.
They serve as storage for food or ingredient.
The vacuole ma’am! Fridge stores food that the
costumers will eventually eat and it is the same as the
vacuole that stores food that the cell takes in.
The janitor in the restaurant represents the lysosome
because they are the one who digests old cell parts.
The mitochondria.
The take out boxes represents the Golgi apparatus
because the Golgi apparatus modifies, sorts and
packages proteins and other materials for storage, just
like the take out boxes which is use for storing food.
The cytoskeleton gives the cell shape and internal
organization
No ma’am.
