Ribosomes  Description:  Made of protein and RNA  Very small, spherical shaped  Function:  Make proteins  Analogy

Cytoplasm  Description:  Jelly-like substance that fills the cell and surrounds the organelles  Function:  Fills space between organelles  Contains materials needed by the organelles  Analogy

Flagella  Description:  Long, thread-like extension of a cell  Function:  Helps cell move  Analogy

Cilia  Description:  Short, hair-like projection on the cell surface  Function:  Used to sweep away things from the cell surface or help the cell move through fluid  Analogy

Nucleus  Description:  Core, central portion of cell  Function:  Contains genetic information (DNA)  Directs cell activities  Analogy

Nuclear Membrane  Description:  Double-layer membrane surrounding the nucleus  Function:  Separates nucleoplasm from cytoplasm  Analogy

Nucleolus  Description:  Round structure within nucleus  Made of protein and RNA  Function:  Makes ribosomes  Analogy

Chloroplast  Description:  Oval or bean shaped structure with green color  Function:  Helps capture sunlight to produce food (energy) for plants  Analogy

Golgi Apparatus  Description:  Flattened sacs called cisternae  Function:  Modifies and packages materials created in the cell for transport (inside or outside of the cell)  Analogy

Lysosome  Description:  Small sacs  Function:  Use digestive enzymes to breakdown old/worn-out organelles, viruses or bacteria, and/or food particles  Analogy
