CELL STRUCTURE AND COMPARTMENTS QUIZ

Where in a eukaryotic cell, DNA can be found?

Mitochondrion

Nucleus

Both (a) and (b)

Vacuole

TRUE ANSWER : ?
YOUR ANSWER : ?

According to the fluid mosaic model of cell membranes,

the membrane is a highly mobile mixture of phospholipids and proteins

the unique properties of cell types are determined by their phospholipids

the most common type of molecules in the membrane are proteins

basic membrane structure results from how the proteins interact with water

TRUE ANSWER : ?

Endoplasmic reticulum

Golgi apparatus

TRUE ANSWER : ?
YOUR ANSWER : ?

What do dystrophin, utrophin, actin, and tubulin have to do with eukaryotic cell structure and function?

They all participate in the production of large amounts of ATP

They are components in the reactions of photosynthesis

They all participate in the degradation of large amounts of ATP

They are all embedded proteins in plasma membranes

TRUE ANSWER : ?
YOUR ANSWER : ?

Which of the following structures is expected in a bacterium?

Endoplasmic reticulum

Nucleus

Golgi apparatus

Plasma membrane

TRUE ANSWER : ?
YOUR ANSWER : ?

Eukaryotic cells are more efficient than prokaryotes because their internal compartmentalization

reduces overall cell size

allows for specialization through merging of different tasks

makes each compartment nutritionally independent of all others

allows for specialization through the subdivision of particular tasks

TRUE ANSWER : ?
YOUR ANSWER : ?

The highly folded membranes found in such eukaryotic organelles as mitochondria and chloroplasts

assist with cell movement

make it possible to package large amounts of DNA within the cell

increase the surface area where key chemical processes can occur

help the cell against physical damage
