Midterm Review: Study Guide # 2
TOPICS: Cell Transport & Cell Division
Please read before studying:
1. First, take time to review your Study Guide #1 Worksheet before beginning Study Guide #2.
1. After you are done, locate your guided notes and any other associated sheets for ALL the topics
listed above.
2. Next, scan the objectives for the topic you are about to study in order to get a sense of what
you should be focusing your time and energy on.
3. Start mastering each objective by answering the associated review questions right on this sheet.
4. After you have finished, use this sheet as a study tool to quiz yourself. Quiz yourself by trying to
answer all the questions aloud. This will probably take you a few times to feel comfortable. You are
finished studying when and only when you can answer 100% of the objectives correctly without
having to look back at your notes for help.
Topic # 4 – Cell Transport
 I am able to describe All 3 types of cell transport
Cell Transport
What is moving?
Direction of Movement?
Is Energy Required?
Diffusion
Osmosis
Particles or molecules
Water
High  low
High  Low
No
No
Active Transport
Large molecules
Low  High
Yes
 I am able to provide examples of diffusion:
 Example # 1 – perfume particles spreading in air
 Example # 2 – food dye spreading in beaker of water
 I am able to describe the movement of water if given a scenario:
 Raisins are placed in a beaker of freshwater.
 What will happen to shape of the raisins? Explain using the words high water
concentration and low water concentration.
Raisins will swell. Water will move from High concentration in the
beaker to low concentration in the raisin.

Period:____
These raisins are now placed in a beaker of salty water.
 What will happen to the shape of the raisins? Explain using the words high water
concentration and low water concentration.
Raisins will shrink. Water will move from high concentration in the
raisin to low concentration in the beaker.

A red blood cell is placed in a beaker of water that has an equal water to salt
concentration.
 What will happen to the shape of the cell? Explain.
It will stay the same. Water will move in and out of the cell at the
same rate.

A freshwater fish is placed in a salt water aquarium.
 What will happen to the fish? Explain using the words high water concentration
and low water concentration.
Fish will shrink. Water will move from high concentration in the fish
to a low concentration in the tank.
Topic # 5 – Cell Division
 I am able to state the order of the cell cycle and describe what happens in each stage:
 Interphase – cell grows bigger and DNA doubles (replicates)
 Mitosis – nucleus divides and chromosomes are separated
 Cytokinesis – cytoplasm is divided and cell splits into two
 I am able to state the main goal of mitosis:
 What is the main goal of mitosis? To divide one cell into 2 cells each with the
SAME number of chromosomes as the original
 I am able to state the order of the 4 phases of mitosis (PMAT) and thoroughly describe the events
that happen in each stage (NOTE: Remember our hints for each phase):
 Prophase

Chromatin condenses into chromosomes

Nuclear membrane disappears

Spindle fibers appear
 Metaphase

Spindle fibers move duplicated chromosomes to middle

Date:_______________
Period:____
 Anaphase
 Spindle fibers pull chromosomes to opposite ends of the cell
 Telophase
 Chromosomes uncoil into chromatin

Nuclear membrane reappears

Spindle fibers disappear
 I am able to identify interphase, the 4 phases of mitosis, and cytokinesis if given a diagram.
 Can you correctly identify all 6 diagrams on your Worsheet titled “STAGES OF
MITOSIS.” This can be found in your Assignments section of your binder?
 Circle one: YES or NO
 If you cannot find this worksheet make sure to copy one from a friend.
 Correctly order (using the numbers #1-4) AND name these diagrams of mitosis.
2 Metaphase

3 Anaphase
4 ______
Telophase
1 prophase
______
I am able to describe how cytokinesis differs in plant and animal cells:
 How is cytokinesis different in plant and animal cells?
Animal  cell membrane pinches inward
Plant  Cell plate forms in between each new cell
