2.  Located around the outside of the cell  Contains proteins and lipids  Surrounds the cytoplasm of a cell  Serves almost the same purpose as skin Cell Membrane

3.  Enclosed by the cell membrane  Keeps cell organelles separate  Contains mostly water and protein material  Where most of the cell activities occur

4. TThey are hair-like EExtend from the surface of the cell CCilia are shorter whereas flagella are longer and whip-like AA cell that has cilia usually has them all over, while there are only a few flagella UUsed for locomotion Hair-like CILIA Whip-like FLAGELLA

5. Ribosomes  The protein builders of the cell  Connect one amino acid at a time  Found all around the cell, including floating in the cytoplasm  Are split into two subunits: 60-S is large, while 40-S is small Ribosome 60-S 40-S

6. -Surrounded by a double membrane -Tube-like -The inner membrane is highly folded -Release food energy from food molecules -Sometimes referred to as the “POWERHOUSE” of the cell Mitochondria and its inner structure. NOTE: two membranes.

7.  The communicator of the cell…communicating with the surrounding cytosol  Holds the DNA  Nucleolus makes ribosomes  Most obvious organelle

8.  Like a labyrinth  Rough ones are covered with ribosomes, the smooth ones are not  In charge of moving proteins and other carbs to the Golgi apparatus, plasma membrabe, lysosomes, or where needed  The smooth ER is where vesicles are budded off

9.  Processes proteins  Found in 1898 by Camillo Golgi  Made of membrane-bound stacks called cisternae  Normal Golgi can have 3 to 7 cisterna stacked like dinner plates  Used for cell secretion

10.  Contains digestive enzymes  Digest worn-out organelles, food particles, and viruses or bacteria take in by the cell  Require a 4.5 pH level  Lysis is Greek for destruction and soma means body  More acidic than the cytosol

11. Smooth endoplasmic reticulum mitochondriaribosomeCell membrane nucleolous Rough endoplasmic reticulum nucleus Nuclear envelope Golgi apparatus
