- 4. OBJECTIVES • Identify thedifferent types of cell based from their structures. • Differentiate the organelles found in plant and animal cell • Give the importance of cell in every living organism.
- 5. REVIEW TIME! What isthe basic unit of all living things? CELL
- 6. REVIEW TIME! What laboratoryapparatus cytologist or scientists used to view cell? MICROSCOPE
- 7. REVIEW TIME! These arespecialized parts of the cell that are similar to organs. Also called as ‘little organs’. O R G ANELLE S
- 9. TYPES OF CELL Prokaryotes -NO NUCLEUS - Small and Simple – few organelles - Have cell membranes and cytoplasm - Ex. Bacteria Eukaryotes - Contain nuclei - Contains organelles that perform specialized functions - Uni-or multicellular

- 33. Q1 Compare the shapeof a plant cell with that of an animal cell as shown in Figures 1 and 2. Plant cells are rectangular or angular or rigid in shape, while animal cells are rounded and somewhat irregular or spherical or cylindrical.
- 34. Q2 Which cell partsare found in both cells? The nucleus, plasma membrane, cytoplasm, the mitochondrion, rough and smooth endoplasmic reticulum, Golgi body, vacuole/vesicle, ribosome/s and lysosome are common to both plant and animal cells.
- 35. Q3 Which cell partsare present only in animal cells? The centrioles are present in animal cells only.
- 36. Q4 Which cell partsare present only in plant cells? The cell wall and chloroplasts are present in plant cells only.
- 37. Q5 What do youthink will happen to the cell if the plasma membrane does not function properly? Without the plasma membrane, any substance can go in and out the cell. The cell may be affected by the exit of needed substances or entrance of unneeded or poisonous substances that may lead to death of the cell.
- 38. Q6 What is thepurpose of the cell wall in plants? The cell wall being made of tough or rigid material gives shape and protection to plant cells.
- 39. Q7 Why are thereseveral chloroplasts in the plant cell? The chloroplast in cells of plants is where food is made. The greater the number of chloroplast in them makes them efficient in making more food for the plant.
- 40. Q8 How would vacuolesin plants serve as defense against animals that eat them? Vacuoles in some plants may contain poison or toxic substances. These substances can harm these animals, once eaten. So, this serve to protect them.

- 44. The Cell Theory •All living things are composed of cells • Cells are the basic units of structure and function in living things • New cells are produced from existing cells
