Question 4

FLuid Mosaic Model; FLuid

Answer 4

Fluid comes from the movement of the phospholipids

Question 5

Fluid Mosaic Model: Mosaic

Is a phospholipid bilayer

Question 7

Nuclear envelope protects what?

Answer 7

Nucleus

Question 8

Envelope is…

Answer 8

continuous with the ER

Question 9

Nuclear Pores

Answer 9

Move contents in and out of the nucleus

Question 10

Nucleus contains.

Answer 10

DNA and histone proteins

Question 11

Nucleolus is a condensed mass of..

Answer 11

rRNA

Question 12

What determines what passes through Nuclear Pore?

Answer 12

Nuclear pores are selective. Only certain things can come in and out

Question 13

Nucleases

translate the mRNA into a sequence of amino acids that synthesize proteins

Part rRNA and part protein

Question 18

Ribosomes assembly

Answer 18

Partially assembled in nucleolus, whole assembly in the cytoplasm

Question 19

Rough ER

Answer 19

Contains ribosomes that produce membrane and secretory proteins. Proteins moved via transport vesicles

Produces lipids and steroids; helps detoxify drugs

Question 21

Golgi

Answer 21

Processes and modifies chemical products of the cell; works in partnership with the ER

Question 22

Lysosome

Answer 22

Contains digestive enzymes, absent from most plant cells, break down many macromolecules (proteins, sugars, fats, nucleic acid)

Question 23
