Introduction
Good day fellow learners.
Did you know that there are around 37 trillion cells in the body of an average person and that an average sized human contains more than 39 trillion bacterial cells – more than the actual cells of the body.
Today we will be exploring the cells , the types we get and the parts of a cell.

Task
At the end of the lesson you are expected to be able to:
1. Understand the basic concept of cells.
2. Distinguish between the two types of cells.
3. Locate and explain the parts of a cell.
Process
NOW then...Now lets proceed my fellow biologists!!!
Task 1: Fill in the missing words with the provided answers in the correct sentences.
| Prokaryotic | Organelles | Eukaryotic | Ribosomes | Nucleus |
- The main difference between prokaryotic cells and eukaryotic cells is the presence of a.....
- Having.....makes eukaryotic cells much more efficient at completing important cellular functions.
- Prokaryotic cells contain various structures that help with certain functions, such as.....
- ....cells can grow much larger than.....cells

Evaluation
At the end of the lesson the learners will be able to meaningfully reflect on what they have learned in the lesson on cells and the importance of it in the study of biology.
They will also be able to reflect on their answers by consulting the memorandum with the teacher

TASK 3
|
PARTS OF A CELL |
PART FUNCTIONS |
|
Cell membrane |
It is the outer boundary of animal cells. |
|
Cytoplasm |
It is a jelly-like substance that fills complete cell inside the cell membrane. All the structure inside a cell float in the cytoplasm. |
|
Nucleus |
This organelle contains the DNA of a cell and acts a brain. It is responsible for instructing the cell to do various tasks. |
|
Endoplasmic Reticulum |
It is a network of canals that are spread throughout a cell to transport materials from one part to another. |
|
Mitochondria |
These organelles are the powerhouses of a cell that generate energy from food that we eat and the oxygen that we breathe. |
|
Ribosomes |
These organelles produce various things for a cell to function well such as proteins. |
|
Lysosomes |
These organelles get rid of waste materials that are produced by a cell while performing various tasks. |
|
Golgi Bodies |
These organelles store the protein temporarily. |
|
Vacuole |
Vacuoles are the storage organelles of a cell that can store food, water, minerals, and waste materials. |
Conclusion
This activity is important as it fundamentally important in the understanding of cells. The cell is the most basic form of life essentially. Anything that is living fundamentally is composed of cells. We study the cell because it is the simplest unit of all living organisms and to begin understanding life, we must realize the cell’s structure, whether it is about the different types of cells or how the cell functions.
Congratulations!! You are now at the end of the lesson on cells.
Thank you for your cooperation and continue to strive for success!!
