Semi-detailed Lesson Plan in Cell Biology
I. Objectives :
At the end of the 90-minute discussion, the students should be able to:
determine the parts of the cell membrane and the cell wall;
describe the cell wall and cell membrane’s structure and function; and
state the importance of selecting people who will enter and influence our
lives.
II. Subject Matter:
A. Topic: Cell Membrane and Cell Wall
B. Reference: whatislife.com/education/fact/history_table.html

C. Materials: PowerPoint Presentation, illustration boards
III. Procedure:
A. Routinary Activities
1. Greetings
2. Classroom Management
3. Prayer
4. Checking of Attendance
5. BioBits(Trivia of the Day)
6. Drill:
Scrambled Cell
The class will be divided into two groups and shall pick a representative.
Scrambled letters will be flashed on the screen and the students should guess what term
is it. Answers shall be written on the illustration boards given. The group with the
highest point wins.
Pictures of a bank robbery will be flashed on the screen and the teacher will ask the following questions:
• Imagine our establishments, houses and school are permeable to anyone, what do you think will happen to our everyday life?
• Do you think cells also need guards or barriers to protect what’s inside them?

7. Review:
The cell is the basic unit of life. Our body is made up of millions and billions
of them. A cell is like a tiny system. Inside the cell are organelles with different
functions. Among these organelles are: nucleus, mitochondria, Golgi bodies, cell
membrane and cell wall.
B. Motivation:
C. Lesson Proper
Task 1: Using a PowerPoint presentation, the teacher will present the topic
deductively.
The cell is composed of many organelles like the mitochondria, ribosomes,
nucleus, endoplasmic reticulum etc, but before getting into the inside, we must first
pass through an opening, and the passages into the inside of the cell are the cell wall
and the cell membrane.
Cell Wall
History
The cell wall was discovered by Robert Hooke in 1665. Cell wall is a
rough, generally flexible layer that surrounds some types of cells. It is
situated outside the cell membrane and it provides these cells with
structural support as well as protection.
Structure
While cell membranes might be around every cell, cell walls made of
cellulose are only found around plant cells. Cell walls are made of specialized
sugars called cellulose.
Cellulose provides a protected framework for a plant cell to survive.
It's like taking a water balloon and putting it in a cardboard box. The balloon
is protected from the outside world. Cellulose is called a structural
carbohydrate (complex sugar) because it is used in protection and support.
