CELL STRUCTURE AND COMPARTMENTS QUIZ

An organism's first line of defense against attack by an invader such as a virus or bacterium is usually

its body wall

a nonspecific immune response

a specific immune response

to flee or hide

TRUE ANSWER : ?
YOUR ANSWER : ?

According to the fluid mosaic model of cell membranes,

the most common type of molecules in the membrane are proteins

basic membrane structure results from how the proteins interact with water

the unique properties of cell types are determined by their phospholipids

the membrane is a highly mobile mixture of phospholipids and proteins

TRUE ANSWER : ?
YOUR ANSWER : ?

A certain cell organelle which is made of a double phospholipid bilayer that has many large pores in it, is most likely

the cytoskeleton

the nuclear envelope

the mitochondrion

the plasma membrane

TRUE ANSWER : ?
YOUR ANSWER : ?

Lysosomes are specialized vesicles in that contain digestive enzymes for the breakdown of food. A related organalle known as a vacuole, which is found in , also contains enzymes but in addition may act as a storage organelle for nutrients or water.
