Cell+Parts+&+Functions

Title: Cell Analogy (Copy the numbered items on one page and add to the drawing with each additional number on another page.)

1. The different parts and activities of a cell can be compared a factory.

2. The parts of a cell are called organelles.

3. The activities that a cell does are called functions.

4. A cell is surrounded by the cell membrane.

5. Like a fence, the cell membrane controls what goes in and out of the cell.

6. Like a computer holding blueprints and fabrication programs, chromosomes contain the instruction for directing the activities of a cell.

7. Like a control room, the nucleus surround by the nuclear envelope controls the activities of the cell. 8. The nuclear envelope is membrane with pores that controls what goes in and out of the nucleus.

9. Like a power plant, the mitochondria converts the energy in food to energy the cell can use.

10. Like an assembly line, the endoplasmic reticulum is where stuff is made.

11. Like robots, ribosomes make the proteins produced by the cell.

12. Robots need instructions to make things and so do ribosomes. Messenger RNA takes instructions from the chromatin to the ribosomes for making proteins.

13. Like stuff made by robots, the proteins produced by ribosomes are used to build and do things in organisms.

14. Like a packaging room, the Golgi body puts a membrane around materials that need to be transported.

15. The nucleolus is a darker area in the nucleus where ribosome parts are made.

16. Like a garbage service, lysosomes contain chemicals that break down things in the cell.
