Ribosomes are organelles that	Float in the cytoplasm and attach to the endoplasmic reticulum.
Cisternae of this organelle are continuous with the nuclear envelope.	Rough ER
Of the following, the only organelle that has a double membrane structure is the	Mitochondrion
A major function of the cell membrane is to	Control what enters and leaves the cell.
Which of the following is not a cytoskeleton element?	Centriole

Which area of the cytoplasm near the nucleus coordinates the building and breaking of microtubules in the cell?	Centrosome
This organelle primarily modifies products from the rough ER, and it resembles a stack of hollow saucers, one cupped inside the next.	Golgi Apparatus
This organelle has both a cis and a trans face.	Golgi Apparatus
Which letter indicates the Rough ER?	The letter is C.
Which of the following statements about integral proteins in the plasma membrane is false?	They are more abundant by volume than the membrane phospholipids.
The outer boundary of a human cell is called the	Plasma Membrane
Which type of junction is formed when membrane channels of adjacent plasma membranes adhere to each other?	Gap Junction
Which letter indicates the nucleolus?	The letter is A.
The inside of the cell is composed largely of a gel-like substance called	Cytoplasm
Ribosomes may be either free within the cytoplasm or bound to a membrane system known as the	Rough ER
The plasma membrane is composed of all of the following except	Tubulin Protein
This membranous organelle contains oxidase and catalase enzymes.	Peroxisomes
