Most eukaryotic cells have a membrane-bound ________ that contains the genetic material.

Intracellular structures surrounded by membranes, such as mitochondria and lysosomes, are referred to as ________.

The plasma membrane regulates the transport of molecules into and out of the cell by allowing only certain substances to pass; thus it is said to be ________.

If a red blood cell, or any other type of human cell, is placed in a hypertonic solution, water enters the cell, causing it to swell and eventually burst.

Glycolysis can occur in the presence or absence of oxygen.

Water moves via osmosis from an area with a lower solute concentration to an area with a higher solute concentration.
