B. Cell Structure and Function

Question 1

-encloses cell for support, protection and
passage of substances
-semi-permeable
-made up of phospholipid bilayer

Answer 1

Plasma Membrane

Question 2

A describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments.

Answer 2

Fluid Mosaic Model

Question 3

Describe Isotonic Solution

Answer 3

No osmotic flow

Red Blood Cell appear normal in size and shape

Question 4

Describe Hypotonic Solution

Answer 4

Water flows into the cell

The swelling may continue until the plasma membrane ruptures, to lyses

Question 5

Describe Hypertonic Solution

Answer 5

Water moves out of the cell

Red blood cells crenate (shrivel)

Question 6

Cellular material outside the
nucleus but inside the
plasma membrane

Contains:
⮚ organelles
⮚ cytosol

Answer 6

Cytoplasm

Question 7

A fluid portion of the cytoplasm. It is a viscous solution containing dissolved ions and molecules such as proteins

Answer 7

Cytosol

Question 8

Control center of the Cell

Answer 8

Nucleus

Question 9

________in the nucleus
provides the original information
needed to fulfill the cell’s needs

       This nuclear information  
       contributes to \_\_\_\_\_,  
       \_\_\_\_\_\_\_\_, and the many 
       activities of the complex cell  
       “factory”

Answer 9

DNA

Growth, Differentiation

Question 10

Stores hereditary information,
which is passed from cell to cell
as new cells are formed

Answer 10

Nucleus

Question 11

Question 20

Continuous with the outer membrane
of the nucleus

Facilitates cellular communication
and channeling of materials

Extensive that it constitutes more
than half of the membranous
surfaces within the cytoplasm of
most cells

Answer 20

Endoplasmic Reticulum

Question 21

Form of ER that has no or few ribosomes

Answer 21

Smooth ER

Question 22

Associated with the synthesis, secretion, or storage of proteins
