Cell Wall

 Description:

Rigid outer layer

 Outside of cell membrane

 Function:

 Support

 Protection

 Helps cell maintain its shape

 Analogy

Cell Membrane

 Description:

 Outside covering of cell made of lipid bilayer

 Function:

 Barrier between cell and its environment

 Controls what substances can enter or leave the cell

 Provides support and protection, especially in cells without a cell wall

 Analogy

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

Mitochondrion

 Description:

 Spherical or rod-shaped

 Inner and outer membranes

 Function:

 Converts sugars into ATP (energy) for the cell

 Analogy

Plastid

 Description:

 Double-membrane bound organelle

 Function:

 Involved in food storage; function depends mostly upon which pigments are present

 Analogy

Rough Endoplasmic

Reticulum

 Description:

 System of membranous tubes and sacs with ribosomes on the surface (making it appear rough)

 Function:

 Helps make and transport new proteins to Golgi apparatus or outside of the cell

 Analogy

Smooth Endoplasmic

Reticulum

 Description:

 System of membranous tubes and sacs

 Function:

 Makes lipids

 Creates and stores steroids

 Stores ions that cells might need

 Metabolizes carbohydrates

 Analogy

Vacuole

 Description:

 Sacs: smaller in animal cells, larger in plant cells

 Function:

 Store a variety of things such as water, nutrients, or waste products

 Analogy

Vesicle

 Description:

 Small sacs

 Function:

 Stores, transports, or digests materials within the cell

 Analogy
