1. Cell Review
Organelles and Functions

2. Cell Membrane Find it and color it on your diagram
Function: holds shape, allows materials in and out selectively
Endocytosis
Exocytosis

3. Nucleus
Find nuclear membrane, nucleoplasm, and nucleolus and color them
Function: regulates passage of materials; contains chromatin;a mass of RNA that forms rRNA involved in protein synthesis

4. Cytoplasm Find and color it
Function: contains organelles; the gel-like material inside the cell membrane (excluding nucleus)

5. Endoplasmic Reticulum
Rough-has ribosomes
Smooth-does not
Find and color them
Function: Rough ER transports proteins; Smooth ER makes steroids, stores calcium in muscle cells, and breaks down toxins in liver

6. Ribosomes Find and color some
<>
Find and color some
Function: the site of protein synthesis, as directed by mRNA from the nucleus

7. Golgi Apparatus or complex
Find it and color it
Function: Produce vesicles by budding off edges, collect secretions and package them for export or cell use, such as a lysosome

8. Mitochondrian Find and color it
Function: energy for cell operations is generated here

9. Vacuoles Find it and color
Function: merge with cell membrane and each other for transport

10. Lysosome Find and color
Function: container of enzymes to break down other structures such as nutrients and damaged cell parts

11. Microtubules and Microfilaments
Find and color
Function: provide support and hold shape of cell

12. Centrioles Find and color
Function: Give rise to spindle fibers used by chromosomes in cell division
