1. Unit 4 Review Questions

2. What is an Isotonic solution?

3. It is a solution where there are an equal amount of solutes on both sides of the cell membrane. The cell has reached equilibrium.

4. Name one difference between PASSIVE & ACTIVE transport?

5. Passive does not need energy and active does.
Passive goes from high to low concentrations, and active goes from low to high conecntrations.

6. __________________ _____X_________
In a chemical equation, explain what the elements on the right side of the yield sign are called.
__________________ _____X_________

7. Products

8. What is the difference between osmosis & diffusion?

9. Diffusion involves the movement of PARTICLES across a membrane and Osmosis involves the movement of WATER across the cell membrane.

10. Endocytosis and Exocytosis are examples of what type of transport?

11. Active Transport

12. Name the products of photosynthesis.

13. Glucose, & Oxygen

14. What organelle is responsible for photosynthesis inside a plant cell?

15. Chloroplast

16. Explain the relationship between photosynthesis and cellular respiration.

17. The equations are opposites of each other.
The reactants for CR are the products for PS, and the products for CR are the reactants for PS.
Each one makes the reactants that the other one needs to complete the process.

18. Draw a cell that is hypotonic compared to the solution around it.

19. Passive transport is when particles go from an area of __________ concentration to an area of _________ concentration.

20. High to Low

21. Exocytosis moves particles ________ the cell, using energy.

22. Out

23. This type of active transport: ____________ moves particles into the cell, using energy.

24. Endocytosis

25. Name all of the reactants needed in Photosynthesis.

26. Sunlight (energy), water and Carbon Dioxide

27. What part of the chloroplast makes plant pigment?

28. Chlorophyll

29. List two examples of Passive Transport.

30. Osmosis & Diffusion

31. Name all the reactants needed to complete cellular respiration.

32. Sugar & Oxygen

33. Why doesn’t passive transport require energy?

34. Because it is going from high to low concentration and this happens naturally.

35. Name the following Equation

36. Cellular Respiration

37. What is the form of energy created during cellular respiration?

38. ATP

39. Explain what diffusion means.

40. It is when solutes go from an area of high concentration to low concentration across a cell membrane.

41. Which diagram shows the correct direction for water in diffusion?

42. B

43. Draw a cell that is hypertonic compared to the solution around it.

44. Name the products of Cellular respiration.

45. Carbon Dioxide, Water and ATP

46. In a chemical equation, explain what the elements on the left side of the yield sign are called.

47. Reactants

48. Name the following equation

49. Photosynthesis

50. Active transport is when the particles go from an area of _____________ to ______________.

51. Low to High

52. Why does active transport require energy?

53. Because the molecules are going from an area of low to high concentration.
