DETAILED LESSON PLAN I.
Objectives: At the end of the discussion, the learners should be able to: Distinguish prokaryotic and eukaryotic cells according to their distinguishing features Describe the structure and function of major and subcellular organelles
Subject matter: A. Topic:
1. Prokaryotic vs. Eukaryotic cells 2. Cell Structure and Functions
B. Instructional materials:
power point presentation White board Black pen
k-12 Education Curriculum Senior High School- STEM Specialized Subject STEM_BIO11/12-Ia-c2 STEM_BIO11/12-Ia-c3
Procedure: A. Preliminary activity 1. Opening prayer 2. Checking of attendance 3. Review (the cell theory and the meaning of the cell) The cell was discovered by Robert Hooke in 1665. by 1839 Matthias Jakob Schleiden and Theodor Schwann, states that cells are the fundamental unit of structure and function in all living organisms and that all cells contain the hereditary informationfor transmitting information to the next generation of cells. 4. Motivation (giving of actual setting examples to the learners that enrich the new lesson) B. Lesson proper Teacher’s activity Student’s activity 1. Presentation Good morning everyone I will be your teacher today, I’m Ms.FEBIE PALAPUZ but you can call me Ma’am Feb and I’m going to discuss about the different parts of the cell and their vital functions
Good morning ma’am
2. Discussion There are two types of cell. Any idea what are those types? Yes, sir your raising your hand Mr./Ms,_______________
Ma’am, the prokaryotic eukaryotic cell.
Very good answer! Thank you Mr./Ms,______________ Cell are of two types:
Prokaryotic which do not.
Plants, animals, fungi, slime molds, protozoa, and algae are all eukaryotic.
Prokaryoticthey are simpler and smaller than eukaryotic cells, and it is for bacterial cells.
Eukaryote cells are about fifteen times wider than a typical prokaryote and can be as much as a thousand times greater in volume. That’s the difference of prokaryotes and eukaryotes cells Now we will discuss more about the eukaryotic cell. We will tackle the similarities and differences of the plants and animals cells. Are you familiar with the different parts of the eukaryotes cell? Can you give me? Yes, Mr./Ms_______________ That a great answer! Thank you. Very good! Thank you.
(students are raising their hands and giving their idea about the different parts of the cell)
(discussing the different parts andfunction of the cells and giving ample of examples) Cell wall-The outer layer of cell, provides support and protects the plant cell (only in the plant cell) Organelles are parts of the cell which are adapted and/or specialized for carrying out one or more vital functions, Nucleus-
A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis (transcription) occur.
Endoplasmic reticulum (ER) The ER has two forms: the rough ER, which has ribosomes on its surface that secrete proteins into the ER, and the smooth ER, which lacks ribosomes. The smooth ER plays a role in calcium sequestration and release Ribosomes - The ribosome is a
large complex of RNA and protein molecules. They act as an assembly line where RNA from the nucleus is used to synthesize proteins from amino acids. Ribosomes can be found either floating freely or bound to a membrane. A lysosome is derived from the greek words lysis meaning "to loosen", and soma "body". Lysosomes contain digestive enzymes (acid hydrolases). They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria
(the students are listening attentively and cooperating with the different examples)
occurs in the cell mitochondria, which generate the cell's energy by oxidative phosphorylation, using oxygen to release energy stored in cellular nutrients (typically pertaining to glucose) to generate ATP. Responsible for producing most of the chemical energy that cells need to function,
Chloroplasts can only be found in
plants and algae, and they capture the sun's energy to make carbohydrates through photosynthesis Vacuoles Stores water, food, waste
and more for a plant cell. They are often described as liquid filled space and are surrounded by a membrane. I believed you already understand the different parts and their function, if not feel free to ask questions and I am gladly to accept any information added to our lesson.
(Some students will ask for clarification and others will response that they understand the lesson.)
3. Generalization Ok, let’s do the recap.
(students will cooperate with high energy)
We will compare and contrast the different parts and we will give their vital functions. Can anyone give me a brief summary of our lesson today?
(share his/her own understanding about the lesson)
Yes, Mr./Ms.______________ Very Good! Thank you. IV.
Evaluation Teacher’s activity A. (this will take 5 minute)
So for your quiz, get a ¼ sheet of yellow (students get their paper) paper and number it from 1 to 15
(answers) 1 and 2. What are the two types of cells and give a brief description. 3 to 11. Give the different parts of the cells and their functions 12 and 13. What are the two parts of cell that are not found in animals? 14.What is the photosynthesis?
15. RNA and ribosome helps each other to synthesize amino acids to become _________.
1. Eukaryotes – can be found inPlants, animals, fungi, slime molds, protozoa, and algae cell and Contain nucleus 2. Prokaryotes – can be found in bacterial cell and do not contain nucleus 3. Cell wallThe outer layer of cell, provides support and protects the plant cell 4. Cytoskeletonacts to organize and maintain the cell's shape; 5. Nucleus-A cell's information center 6. Endoplasmic reticulum which has ribosomes on its surface that secrete proteins 7. Ribosomes They act as an assembly line where RNA from the nucleus is used to synthesize proteins from amino acids 8. A lysosomecontainsdigestive
enzymes. They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria 9. Mitochondriagenerate the cell's
energy by oxidative phosphorylation, using oxygen to release energy stored in cellular nutrients 10. Chloroplaststhey capture the sun's
energy to make carbohydrates through photosynthesis 11. VacuolesStore water, food, waste
All done? Now pass your papers and I’ll give you the result tomorrow.
and more for a plant cell. 12. Chloroplasts 13. Cell wall
14. Carbohydrate 15. Protein V.
Assignment Teacher’s activity
And for your assignment, read about cell (students take notes) division That’s for now, hope you learn something today. God bless.
Goodbye and thank you ma’am. Prepared by: FEBIE G. PALAPUZ
