1. and Its Development Al Maahira Junior High School Cell 8th Grade

2. Have you ever seen this kind of pattern on the leaf? If we zoom in this pattern, what will you see? HAVE YOU EVER?

3. Let’s Zoom in!

4. On a leaf organ, when we make a thin slice of the leaf surface and observe it using a microscope, we will find an appearance similar to the image on the right! This collection of cells is called tissue. And in this image, these are plant cells. What do the cells look like? Do they all have a similar shape? They all appear to have angles and be rigid! You will get this result! Beautiful right?

5. HOW ABOUT IN HUMAN OR ANIMAL? Have you ever seen this kind of pattern on your own skin? Let’s take a deeper look on your own skin!

6. HOW ABOUT IN HUMAN OR ANIMAL? Let's try rubbing that skin with a cotton bud, then we observe our skin cells under a microscope! Have you ever heard the term 'dead skin cells'? Our skin cells can indeed die and be replaced with new skin cells approximately every 2 weeks. Therefore, let's try to observe our skin. The outermost layer of skin cells is quite easy to observe because they are easily detached when rubbed. An example is the skin on the inside of the mouth.

7. This is the shape of cells in humans and also in animals, commonly called animal cells. Animal cells appear round, and their outermost part looks elastic and not rigid. Different from plant cells, where the outermost part of the cell looks rigid, right? You will get this result!

8. Have you ever used microscope before? It’s Time for Observation !

9. 01 CELL

10. CELL Cell is the smallest functional structure of living things Cell are composed of 2 main components: Cell membrane The cell membrane is like the walls and doors of that house. It's the outer layer that holds everything inside the cell. Its main job is to be a gatekeeper. It decides what can come into the cell (like food and water) and what needs to go out (like waste). It's smart, so it only lets the right things in and out, keeping the cell healthy and working properly.

11. CELL Cell is the smallest functional structure of living things 2. Protoplasm Protoplasm is all the living material inside a cell, enclosed by the cell membrane. It consist of : a) Cytoplasm ( sitoplasma ) The jelly-like substance and all the organelles suspended within it (excluding the nucleus). Many metabolism reaction happen in this part b) Organelles ( organel ) Organ of cell that have specific function

12. ORGANELLE CELL

13. Function of Cell Organelles No Picture Organel Name Function 1 Cell wall Protect cell membran and give cell its shape 2 Cell Membran C ontrol what come in and out of the cell 3 Cytoplasm H ome to the cell’s organelle 4 Nucleus C ontrol all cell activity

14. Function of Cell Organelles No Picture Organel Name Function 5 Mitochondrion M ake ATP (energy) or p owerhouse of the cell 6 C hloroplasts Help photosynthesis process 7 Centriol Help cell division 8 Vacuoles Storage, waste management, and structural support

15. Function of Cell Organelles No Picture Organel Name Function 9 Endoplasmic Reticulum D ivided into 2: rough: synthesize protein Smooth: synthesize fat 10 Ribosomes S ynthesize protein 11 Golgi Apparatus P ackage s protein for excretion from the cells 12 Lysosomes S t r ucture containing enzyms that break down

16. What are the differences between them? Feature P rokaryotic C ell Eukaryotic cell Nucleus Prokaryotic Cells Eukaryotic Cells No nucleus (DNA floats freely) Yes, a true nucleus (DNA enclosed in a membrane) Organelles No membrane-bound organelles (like mitochondria, Golgi) Yes, many membrane-bound organelles present Size Generally smaller and simpler Generally larger and more complex DNA Circular DNA, typically in cytoplasm Linear DNA, located in the nucleus Examples Bacteria, Archaea Animals, Plants, Fungi, Protists

17. What are the differences between them? Organel Plant cell Animal cell Cell wall Chloroplasts Centriol e Lysosome Vacuole Big Small

18. 02 TISSUE

19. Tissue in Human and Animal Tissue is a group of cells that have similar structure and that function Kind of tissue in human and animal 1. Epithelial tissue M embranous tissue that form various surfaces throughout the body Function: Protect another tissue 2. Nerve tissue F unction: receive stimuli and send signals to the brain and spinal cord

20. Tissue in Human and Animal Kind of tissue in human and animal 3. Muscle tissue Function: do movement of body parts

21. ORGAN 03

22. Human and Animal’s Organ Organ is a group of tissues that perform a particular function No Picture Organ Name Function 1 Heart supplies the body with oxygen, and removes carbon dioxide from the body 2 Kidney remove wastes and extra fluid from your body 3 Lungs help respiration process 4 Stomach digest food

23. Plant ’s Organ Root : Anchor the plant and soak up water and nutrients from the soil Trunk/Stem : Holds the plant up and moves water and food between the roots and leaves Leaves : Photosynthesis, Gas Exchange, Transpiration
