GENERAL BIOLOGY 1

2. RULES DURING DISCUSSION:
• Turn off your microphone when I am discussing and you just have to turn on
your microphone if you are going to give answers, ask questions/clarifications.
• If possible, turn on your camera.
• Students who will participate will be given points.
• There is one student who will going to do screen record in our discussion.

3. CELL STRUCTURE AND
ITS FUNCTION
1

4. Learning competency:
 Describe the structure and function of major and subcellular organelles–
STEM_BIO11/12-la-c-2
 Distinguish prokaryotic and eukaryotic cells according to their distinguishing
features– STEM_BIO11/12-la-c-3

5. WHAT IS A CELL?
 the smallest unit that can live on its own and that makes up all living
organisms and the tissues of the body.

6. THREE MAIN PARTS OF THE CELL
controls the substances that go into
and out of the cell.
The semifluid substance of a cell. It
is where the chemical reactions take
place.
The control center of the cell.
Contains the genetic information.

7. Subcellular organelles – “little organs”

8. act as packaging elements for
the DNA.

9. Which is a structure where ribosomes are made.

10. A micro-machine for making proteins.

11. rER - Protein production
sER – Lipid production

12. Protein modification and export.

13. Protein modification and export.

14. Stores cell sap, a solution of
sugar and salts.

15. Garbage collector.
They break down
excess or worn-out
cell parts. They may
be used to destroy
invading viruses and
bacteria.

16. Energy production

17. The structures that help cells maintain their shape and internal organization, and it also
provides mechanical support that enables cells to carry out essential functions like
division and movement.

18. Microtubule organizers.

19. Can store or digest certain
secreted molecules.

20. Lipid destruction; contains
oxidative enzymes.

21. PROKARYOTIC VS.
EUKARYOTIC CELLS
1
2

22. EUKARYOTIC CELLS
 are found in plants, animals, human, fungi, and protists. Their DNA is
contained within a membrane-bound nucleus.
PROKARYOTIC CELLS
 are found in bacteria and archaea. Their DNA is not contained within a
nucleus. Instead, their DNA is circular and can be found in a region called the
nucleoid, which floats in the cytoplasm.

25. VALUES INTEGRATION:
 Why we need to know about cells?
 helps us understand how organisms, including humans, function. After all, our
bodies are made up of trillions of cells. By learning about cells, we come to
understand how we can:
 • protect cells to prevent infection and other harmful effects
 • observe cells to diagnose disease
 • treat cells to heal illnesses
 • stop harming cells through our choices and actions

26. ASSESSMENT:
Direction: Do the task given and put it in a
long bond paper.
 1. Illustrate the human cell and label its parts and identify its function.
 2. List the other differences of prokaryotic and eukaryotic cells.
