|
Eucaryotic cell boundaries are?
|
Cell wall
Cytoplasmic membrane |
|
|
Define Glycocalyx? What is it composed of?
|
Outermost boundary that comes in contact with the environment.
Usually composed of polysaccharides. |
|
|
How does the plasma membrane of eucaryotic cells differ from that of procaryotes?
|
similar in function, but differ in composition, possessing sterols as additional stabilizing agents. They are very important to cells that lack a cell wall.

|
Golgi apparatus
|
|
|
How does the mitochondria differ from other organelles?
|
They divide independently of the cell, contain DNA and have 70S ribosomes (same as procaryotic cells)
|
|
|
