9 Weeks Study Guide
Answer the following questions:
1. What work together in an organ? TISSUES
2. List the three parts of the cell theory? CELL IS THE BASIC UNIT OF LIFE, ALL ORGANISMS COMPOSED OF
ONE OR MORE CELLS, NEW CELLS COME FROM EXISTING CELLS
3. What is produced by mitosis? TWO IDENTICAL CELLS
4. What type of transport occurs when particles move from an area of low concentration to an area of high concentration?
ACTIVE
5. What type of transport does not require energy?
PASSIVE
6. A piece of celery has become wilted. It can become crisp again by what cellular transport process?
OSMOSIS
7. Diffusion of materials can take place in what phase(s) (e.g. solid, liquid and/or gas) of matter?
LIQUID, GAS
8. Where does photosynthesis take place?
CHLOROPLASTS
9. What happens to the chromosomes in the second phase of mitosis?
THEY LINE UP ALONG THE EQUATOR
10. How many stages are there in mitosis?
4
11. What happens before mitosis begins?
AN EXACT COPY OF THE CHROMOSOME IS MADE
12. What happens in the fourth/final phase of mitosis?
THE NUCLEAR MEMBRANE FORMS AROUND THE TWO SETS OF CHROMOSOMES, THEN THEY UNWIND
Define the following terms:
1. multicellular- MORE THAN ONE CELL
2. cell- BASIC UNIT OF LIFE
Identify the cell part:
1. Directs all the activities of the cell.
NUCLEUS
2. This is where food molecules are broken down to release energy.
MITOCHONDRIA
3. This keeps the cytoplasm inside and allows nutrients in and waste products out.
CELL MEMBRANE
4. This is the cellular fluid that surrounds the cell's organelles.
CYTOPLASM
5. A large-membrane covered chamber that stores water and other liquids in plants.
VACUOLE
6. Found only in plant, this structure surrounds the cell membrane and protects and supports the cell.
CELL WALL
7. This organelle produces lipids, breaks down drugs and other substances, and packages proteins for delivery out of the
cell. ENDOPLASMIC RETICULUM

Identify the Controls and Variables
Smithers thinks that a special juice will
increase the productivity of workers. He
creates two groups of 50 workers each and
assigns each group the same task (in this
case, they're supposed to staple a set of
papers). Group A is given the special juice
to drink while they work. Group B is not given the special juice.
After an hour, Smithers counts how many stacks of papers each
group has made. Group A made 1,587 stacks, Group B made
2,113 stacks.
Identify the:
1. Control Group -- Group B
2. Independent Variable -- Special
Juice3. Dependent Variable -- Number
of stacks
4. What should Smithers' conclusion
be?
It doesn’t work
5. How could this experiment be
improved? Answers vary
Homer notices that his shower is covered in
a strange green slime. His friend Barney
tells him that coconut juice will get rid of
the green slime. Homer decides to check this
out by spraying half of the shower with
coconut juice. He sprays the other half of
the shower with water. After 3 days of
"treatment" there is no change in the
appearance of the green slime on either side of the shower.
6. What was the initial observation?
Slime on the shower
Identify the7. Control Group - Side sprayed with
water
8. Independent Variable - Coco Juice
9. Dependent Variable - Appearance of
Slime
10. What should Homer's conclusion
be? It doesn't work
