What are cell parts and their functions?

1. What are cell parts andtheir functions?

2. In this PowerPoint you will learn the following: • different cell parts • what function each part has

3. Even if cells are very tiny, they are made up of smaller parts, and the parts do different jobs.

4. As you can see cells have many parts. This week you will learn about 9 of these parts.

5. cell wall • Surrounds and protects the cell • Makes the cell stiff and strong • only in plant cells. • Its purpose is to shape and protect the cell like the outside wall of a shopping mall, which provides shape and protection for it. • “Supporter and Protector”

6. chloroplast • only in plant cells • contains chlorophyll • captures energy from sunlight and uses it to produce food for the cell • It is like the pizza shop in the mall that makes food. • “Food Producers”

7. cytoplasm • watery, gel-like material in which cell parts move • It is like the hallways of the mall where people move. • “Area of Movement”

8. cell membrane • holds and protects the cell • controls what substances come into and out of the cell • It is like an entrance you have to pass to get into the shopping mall. • “Gate of the Cell”

9. mitochondria • produces most of the energy for the cell • It is like an electrical system of the shopping mall, which supplies electrical energy. • “Powerhouse of the Cell” or “mighty mitochondria”

10. vacuoles • store food, water, and chemicals • It is like water tank and pipes of the mall, which store water. • “Storage Tanks”

11. nucleus • regulates and controls cell activities • acts like the “brain” of the cell • It is like the mall office, which regulates and controls activities of the shopping mall. • “Control Center”

12. nuclear membrane • protects the nucleus • allow substances to pass in and out of the nucleus, as the cell membrane • It is like the main office like the walls of the mall and its entrance, which protect the office and let workers in and out. • “Gate of the Nucleus”

13. chromosomes • The chromosomes direct the activities of cells like a mall office director who works in the office and directs all the activities of the shopping mall. • “Director of the Cell”

14. Golgi bodies Moves materials within and into the cell “packages” proteins “packaging plant” or “bag boy”

15. Endoplasmic reticulum (ER) 2 types—smooth and rough Smooth ER makes lipids; rough ER makes proteins “ER” or “highway”

16. ribosomes Makes proteins Found on rough ER or floating in cytoplasm

19. Practice

20. 1. Choose the wrong statement from the following. a) Mitochondria produces most of the energy for the cell. b) Chloroplasts are “food producers.” c) Cell wall controls the movements of materials into and out of the cell. d) Nucleus regulates and controls all cell activities, acting as the “brain” of the cell.

21. 2. Match the cell part to the nick name. 1) Cytoplasm 2) Nuclear membrane 3) Vacuoles a. Gate of the nucleus b. Area of movement where cell parts move c. Storage tanks

22. 3. This cell part is surrounded by a nuclear membrane. Is it a nucleus? YES or NO

23. 4. This cell part is the powerhouse of the cell. Is it a mitochondria? YES or NO

24. 5. Are these chromosomes? YES or NO
