I . Objectives
At the end of the lesson, the students should be able to :
1. distinguish cellular structures;
2. distinguish the functions of each structures;
3. familiarize what the cell looks like and
4. compare the factory to a cell
II . Topic: Cellular structures and functions
Skill: describing, explaining, illustrating
Materials: pictures, photocopied materials and video clip (cell biology) References:

III. Learning Activity
I will divide the class into group, five members each. Assign a recorder You are going to do this in five(5) minutes.
Show them the different pictures of cell tissues and some parts of cells ( e. g. Ribosomes, mitochondria, lysosomes ).
Allow them to examine the pictures carefully and choose among them is the cell. But before the student give their answers, let them first read the situation below:
B . Presentation
Situation Analysis :
Larry works in a forensic laboratory. His boss James instructed him to get a cell sample from the child victim that has run over by a truck. Which of the following is the cell that Larry should send to James? Teachers ActivityStudent’s Activity From the pictures i have given you, Student will select from the given choose what James should get from the child pictures of tissues, organs, parts of a cell victim.and cell. (5)minutes.
After hearing the student answers,
let them explain why they think their answer
Then allow for differences in answer.
Let’s find out if your choice is correct.
Later on, since Larry is a part of forensic team,
lets see what he actually choose. To find out which
is the cell lets watch this video.
C . Preparation:
Film viewing: (cell organelles and their functions)
NOTE: Take note of the important information about the cell especially its parts and functions.
Follow up questions:
What do you see?
What do you call each of the structure?
In which picture in the previous activity is it similar? What is your idea about the cell?
Teachers ActivityStudent’s Activity
What is your idea about the cell?The cell has many parts Ma’am and Yes Nica.they have their own functions.
Now I will let the students give theirFrom the movie we have just watched answers on the situation analysis.Ma’am, we got it right.
This is a cell ma’am (show the picture).
Very good, you got it right group 2.
So you are now familiar what a cell
Now its time to know and distinguish
the different structures of the cell and
D . Generalization
You are going to compare the factory to a cell.
This time I need five (5) groups, six (6) members each.
Complete the table posted in front: you are given fifteen (15) minutes to answer . “CELL AS A FACTORY”
JOB/PART OF THE FACTORYCELL PARTFUNCTION
I will distribute each student a copy ( poem of a cell ). They are going to fill in the blanks with the corresponding parts of the cell with their functions as their clue. They are given ten (10) minutes to answer. Poem of a cell:
I am a cell
A structure of life
I’ll tell you my components
And what they all do
I have ATP
It and the ___________
Is my buddy too
It covers me
To protect me and...
