C. osmosis
D. transcription

7. 3. Amino acids, sugars, and ions move across the cell membrane
3. Amino acids, sugars, and ions move across the cell membrane. Their movement from a region of high concentration to a region of low concentration is accomplished by special proteins in the membrane.

A. active transport
B. facilitated diffusion
C. osmosis
D. transcription

8. 4. List 3 organelles that eukaryotic and prokaryotic cells have in common. **Reminder for your test: They both have DNA, but Eukaryotes store the DNA in the nucleus ***
Cell membrane, Cytoplasm, Ribosomes

Isotonic
Hypotonic
Hypertonic
Cell A
Cell B

10. 6. Describe the function of part D in the cell membrane pictured.
Transport Protein

11. 7. This component of the cell membrane is used for cell signaling, it contains the elements CHO in a 1:2:1 ratio
Carbohydrates

12. 8. This part of the cell membrane is used to transport large molecules and contains the elements CHON
Transport Protein

13. 9. This part of the cell membrane is has two hydrophobic fats and a hydrophilic phosphate
Phospholipid Bilayer

14. 10. A cell placed in this type of solution will not change shape but stay the same

15. 11. A cell in this type of solution will swell and get larger

16. 12. A cell in this type of solution will shrink, get smaller.

17. 13. A cell that is 90% water and 10% solute is placed in a solution that is 80% water. Draw a diagram representing which way water will flow and describe what type of solution the cell was placed in (Hypo, hyper, iso)
90% water inside the cell is greater than 80% water solution so water will diffuse out of the cell into the solution.
Hypertonic: The cell will shrink

18. 14. A cell that is 50% water and 50% solute is placed in a solution that is 60% water. Draw a diagram representing which way water will flow and describe what type of solution the cell was placed in (Hypo, hyper, iso)
50% water inside the cell is less than 60% water solution so water will diffuse into the cell.
HypOtonic: The cell will swell

19. 15. This organelle is used to make ATP (energy)
MITOCHONDRIA

20. 16. This organelle is found in both prokaryotic and eukaryotic cells and is used for protein synthesis
RIBOSOME

21. 17. Streptococcus bacillus is a bacteria with free floating DNA, what type of cell is it?
PROKARYOTIC

22. 18. Plants have a cell wall made of cellulose and DNA in a nucleus, what type of cells are plants made of?
EUKARYOTIC

23. 19. What type of cell is cell A?
Cell B
Contains Ribosomes
Has a Cell wall
Has a cell membrane
Has Endoplasmic Reticulum
Has no membrane bound organelles
20. What type of cell is Cell B?
PROKARYOTE

24. 20. This is a theory that represents how eukaryotic cells were formed
20. This is a theory that represents how eukaryotic cells were formed. (pro+pro=eu)

26. 22. List 3 similarities between prokaryotic and eukaryotic cells.
BOTH HAVE DNA
BOTH HAVE RIBOSOMES
BOTH HAVE CELL MEMBRANES
BOTH HAVE CYTOPLASM

27. 23. The hypothalamus is the temperature-regulating centre of the brain
23. The hypothalamus is the temperature-regulating centre of the brain. Changes in core body temperature cause the hypothalamus to send nerve impulses to the sweat glands, muscles and blood vessels to raise or lower the temperature. If the core temperature goes up the body loses heat to bring it down again. If the core temperature goes down the body will conserve and even generate heat to bring it up again. This maintaining of internal balance is called___________.
Homepathy
Homeostasis
Homeokarytoic
Homeotelopathy

28. 24. There are 4 types of molecule transport list all 4.

OSMOSIS-water only, high to low, no energy
FACILITATED DIFFUSION-large particles, protein channels, high to low, no energy
ACTIVE TRANSPORT-large particles, protein channels, LOW to high, energy required, ATP

29. 25. This type of molecular transport uses a protein to move solutes from an area of high concentration to an area of low concentration.
