UNIT 3 STUDY GUIDE: CELLS, CELL STRUCTURES, & CELL TRANSPORT (CH 7)
Topics / Concepts:
CELLS and CELL PARTS (7.1-7.2)
prokaryotic vs. eukaryotic cells
CELL PROCESSES (7.3-7.4) - continued
passive vs. active transport (molecular & bulk)
-examples of each type
-use of energy?
-what is transported by each?
cell organelles: structures and functions
differences between plant and animal cells
CELL MEMBRANE and CELLULAR PROCESSES
(7.3-7.4)
cell membranes
-composition
-functions of the various components
-examples of membrane proteins
*OSMOSIS
Hypotonic vs. hypertonic vs. isotonic
-in which direction does water move?
-why?

1) Compare the cellular characteristics of prokaryotes and eukaryotes. (list at least 4 differences)
2) Compare the cellular characteristics of plant and animal cells. (list at least 4 differences)
3) Complete the table below by sketching how an animal cell and a plant cell would react when placed in a
hypertonic, hypotonic, or isotonic environment. In your sketches, use an arrow to show which way water will move
(into the cell, out of the cell, or both in/out equally).

4) What is the primary function of the following cellular organelles:
 Golgi apparatus:
 mitochondrion:
 lysosomes:
 nucleus:
 nucleolus:
 rough ER:
 ribosomes:
 smooth ER:
 vacuole:
 vesicle:
 chloroplast:
 cell membrane:
 nuclear envelope:
 cytoskeleton:
Application / Critical Thinking Questions:
1) What organelles would be especially numerous in a cell that: (explain WHY for each)
-produces large amounts of a protein product?
-requires a constant source of ATP (energy)?
-must perform photosynthesis constantly?
2) Compare and contrast active transport and facilitated diffusion. (How are they similar? How are they
different?)
3) The plasma (cell) membrane is said to be selectively permeable. Describe what selectively permeable means.
4) How are endocytosis and exocytosis similar? How they different?
5) Draw a cross section of a cell membrane, complete with the following parts & processes labeled. It does not
need to be fine art, but each piece should be drawn clearly and be labeled clearly.
A) Plasma (cell) membrane drawn and identify:
i. a single phospholipid
ii. a cholesterol molecule within the plasma membrane
B) Label the inside and outside of cell.
C) Label a carbohydrate used for cell identification.
D) Label a protein channel that is showing facilitated diffusion of a molecule into the cell.
