Unit 1 Study Guide s1

Name:______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 Label the phases of Mitosis

Smithers thinks that a special juice will Identify the: increase the productivity of workers. He creates two groups of 50 workers each and 1. Control Group -- Group B assigns each group the same task (in this case, they're supposed to staple a set of 2. Independent Variable -- Special papers). Group A is given the special juice to Juice3. Dependent Variable -- Number drink while they work. Group B is not given the special juice. of stacks After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 4. What should Smithers' conclusion 2,113 stacks. be? It doesn’t work

5. How could this experiment be improved? Answers vary Homer notices that his shower is covered in 6. What was the initial observation? a strange green slime. His friend Barney tells Slime on the shower him that coconut juice will get rid of the Identify the- green slime. Homer decides to check this out 7. Control Group - Side sprayed with by spraying half of the shower with coconut water juice. He sprays the other half of the shower with water. After 3 days of "treatment" there 8. Independent Variable - Coco Juice is no change in the appearance of the green slime on either side of the shower. 9. Dependent Variable - Appearance of Slime

10. What should Homer's conclusion be? It doesn't work
