3. Draw a basic Plasma membrane, list and explain the purpose of the 4 major parts. 4. Label the different parts of the Prokaryotic cell below. 1. 2. 23 3. 4. 5. 6. 7. 8. 5. What is the difference between Smooth and Rough ER? 8 2

Which of the following are glycoproteins whose function is affected by the common cold birus? a. plasmodesmata b. desmosomes c. cell adhesion molecules d. flagella e. cilia

Unlike eukaryotic cells, prokaryotic cells ________. a. have no plasma membrane b. have RNA but not DNA c. have no nucleus d. a and c

Why is it advantageous for the cell membrane to be fluid in nature?

What controls the passage of molecules into and out of the nucleus? a. endoplasmic reticulum, an extension of the nucleus b. nuclear pores, which consists of membrane proteins c. nucleoli, in which ribosome subunits are made d. dynamically assembled microtubules e. tight junctions

The plasma membrane __________. a. surrounds the cytoplasm b. separates the nucleus from the cytoplasm c. separates the cell interior from the environment d. both a and c

Expalin the difference between cytosol and cytoplasm in both prokaryotes and eukaryotes.

In the fluid mosaic model: plasma membrane proteins orient their hydrophilic sides toward the internal bilayer. phospholipids often flip-flop between the inner and outer layers. the mosaic refers to proteins attached to the underlying cytoskeleton. the fluid refers to the phospholipid bilayer. the mosaic refers to the symmetry of the internal membrane proteins and sterols.

Figure 3.13 Why does the cis face of the Golgi not face the plasma membrane?

A typical prokaryotic cell ________ compared to a eukaryotic cell. a. is smaller in size by a factor of 100 b. is similar in size c. is smaller in size by a factor of one million d. is larger in size by a factor of 10
