In a eukaryotic cell, where is most of the DNA stored?
Nucleus
What portion of the ER is studded with ribosomes on the outer surface of the membrane?
Golgi apparatus
What structure is bounded by a double membrane with infoldings of the inner membrane?
What are the two terms for the motile appendages containing microtubules?
Cilia and flagella
What is the semifluid, jellylike substance in all cells?

What is the literal meaning of the term eukaryotic
true nucleus
What is one function of the smooth ER?
synthesizes lipids, metabolizes carbohydrates, detoxifies drugs and poisons, and stores calcium ions
What is the term for the recycling of a cell's own organic material by the hydrolytic enzymes of lysosomes?
