1. CLASSROOM OBSERVATION 1 S.Y. 2021-2022 Marfe Jan A. Montelibano Presentor

2. PRAYER

3. REMINDERS! Please maintain the social distancing and proper wearing of facemask.

4. CHECKING OF ATTENDANCE

5. Review 1.Who can numerate the levels of organization in an organism? 2. W hat is cells?

6. Motivation (Shows a picture of a door) (Shows a picture of a wall) (Shows a picture of fridge) (Shows a picture of floor, tables and chairs) (Shows a picture of waiter and waitress) (Shows a picture of a take-out box) (Shows a picture of a chef) (Shows a picture of line-up cooks) (Shows a picture of a janitor)

7. Activity Directions:Compare plant and animal cell below. Draw a Venn diagram to show the similarities and differences of the two cells. Write your answers on the manila paper and post it in the board. Late answers will be deducted from their gained points (according to the correct answers given). Choose a representative to report your groups’ work.

8. Comparing Plant And Animal Cells Lesson proper

9. Plant Cell What are the parts? nucleus mitochondrion ribosomes Golgi apparatus cell wall cytoplasm smooth endoplasmic reticulum rough endoplasmic reticulum chloroplast vacuole

10. Cellular structures 1. CELL MEMBRANE For protection Explained by the fluid mosaic model Phospholipid is bilayer interspersed with proteins Fluid because component move throughout the membrane mosaic because of integral proteins, peripheral proteins, glycoproteins, phospholipids, glycolipids, and in some cases cholesterol, lipoproteins.   2. MITOCHONDRION Production of ATP Enclosed by the inner membrane is a jelly-like matrix. folds are called cristae has its own DNA

11. 3. CHLOROPLAST pigment-containing has of small flattened sacs called thylakoids thylakoids are arranged in stacks called granum has its own DNA 4. RIBOSOME Make proteins May be attached (in rough endoplasmic reticulum) or free 5. ENDOPLASMIC RETICULUM May be Rough Endoplasmic Reticulum (RER) Contain ribosomes For protein synthesis Flattened May be Smooth Endoplasmic Reticulum (SER) No ribosomes For lipid synthesis and detoxification Tubular

12. 6. GOLGI APPARATUS modifies and packages materials   7. VACUOLE Surrounded by tonoplast For storage and osmotic regulation   8. LYSOSOME For intracellular digestion Contain digestive enzymes Suicide bag of the cell May destroy cellular debris, pathogenic bacteria and fungi.   9. MICROTUBULES provides structural support and allows motion has protein subunits called tubulin.

13. 10. NUCLEUS Control center of the cell because of the presence of genetic material Surrounded by the nuclear membrane   11. FLAGELLUM/CILIA Has 9+2 microtubular arrangement For movement 12. CENTRIOLES Has 9+0 microtubular arrangement For cellular division   13. NUCLEOLUS Assembles rRNA  

14.   Animal Cell Plant Cell Mitochondria present present Cell wall None Yes Plastids No Yes Vacuole One or more small vacuoles (much smaller than plant cells). One, large central vacuole taking up 90% of cell volume. Ribosomes Present Present Centrioles Always present Only present in lower plant forms. Lysosomes Lysosomes occur in cytoplasm. Lysosomes usually not evident. Plasma Membrane Present Present Cell wall Absent Present Chloroplast Absent Present Nucleus Present Present PLANT AND ANIMAL CELL

15. Analysis In a restaurant, you see its walls. What do these walls represents in the cell?  How about the door of the restaurant? What does it do? On the other hand, the chef is similar to the nucleus, why do you think so? What do you think relates to the cytoplasm in the restaurant?

16. Generalization What is the difference between plant and animal cell? Who can numerate the difference between the Two (2) cells?

17. APPLICATION Question what do you think is the reason why some people are infected with the virus called Covid-19?

18. Evaluation Direction: Choose the letter of the correct answer. 1. Which of the following structures let substances pass in and out of the plant and animal cell? Cell membrane Cell wall Epidermis Mitochondria 2. Which part of the cell contains a green pigment needed for photosynthesis? Centrosome Chromosome Cytoplasm Chloroplast 3. This is the powerhouse of the cell. Lysosome Ribosome Mitochondria Nucleolus 4. Which organelle is found only in a plant cell? Chloroplast Cell wall Both a & b None of the above 5. What part of the cell contains instructions and information to be sent to all parts of the cell? Mitochondria Nucleolus Nucleus Ribosome

19. Assignment Draw a typical cell and label its parts. Submit these in a short bond paper next meeting.

20. TO GOD BE THE GLORY!
