This document contains review questions and answers about various science topics like the circulatory system, respiration, photosynthesis, plant and animal cells, and the digestive system. It discusses how blood carries oxygen from the lungs to the body and carbon dioxide from the body to the lungs. Photosynthesis is described as plants using carbon dioxide, water, and sunlight to produce sugar and oxygen. The digestive system breakdown is also reviewed.

2. What is blood carrying when it is pumped from the heart to the lungs?

3. What is blood carrying when it is pumped from the heart to the lungs? Carbon dioxide is carried in the blood from the heart to the lungs.

4. When blood leaves the lungs, what is it carrying?

5. When blood leaves the lungs, what is it carrying? The blood carries oxygen when it leaves the lungs.

6. What supports the transport of blood through an animals body?

7. What supports the transport of blood through an animals body? Arteries and veins support the transport of blood.

8. Which system transports nutrients and oxygen to the entire body?

9. Which system transports nutrients and oxygen to the entire body? The circulatory system transports oxygen and nutrients throughout the body.

10. Which vessels carry blood from the heart to the rest of the body?

11. Which vessels carry blood from the heart to the rest of the body? Arteries carry blood away from the heart out to the body.

12. What is the job of the kidneys?

13. What is the job of the kidneys? The kidney’s job is to clean the blood . They remove cellular waste.

14. What happens to the cellular waste that is removed from the blood?

15. What happens to the cellular waste that is removed from the blood? Cellular waste leaves the body as urine .

16. What organ stores the urine?

17. What organ stores the urine? The bladder stores urine.

18. Sugar is created in what part of the plant?

19. Sugar is created in what part of he plant? Sugar is created in the plant’s leaves.

20. What is the main substance transported from the plant’s roots ?

21. What is the main substance transported from the plant’s roots ? Water is the main substance transported from the plant’s roots. Water water

22. What is transported by the phloem ?

23. What is transported by the phloem ? Sugar is transported by the phloem from the leaves to all parts of the plant.

24. Which organisms use energy from sunlight to create food?

25. Which organisms use energy from sunlight to create food? Plants are the only organisms that create food from sunlight energy.

26. Where do plants get the energy to grow and reproduce?

27. Where do plants get the energy to grow and reproduce? Plants get the energy to grow and reproduce from sunlight .

28. Where do plants get the carbon dioxide they need?

29. Where do plants get the carbon dioxide they need? Plant get the carbon dioxide they need from the air .

30. Animals produce carbon dioxide. What uses it next ?

31. Animals produce carbon dioxide. What uses it next ? Plants use the carbon dioxide that animals release.

32. What do plants need to transform sunlight into chemical energy (sugar) ?

33. What do plants need to transform sunlight into chemical energy (sugar)? Plants need CO 2 (carbon dioxide) and water in order to make chemical energy (sugar) from sunlight. Energy + CO 2 + H 2 O = sugar + O 2 Sunlight + carbon + water = C6H12O6 + oxygen dioxide

34. What do plant cells and animal cells have in common?

35. What do plant cells and animal cells have in common? Plant cells and animal cells both need sugar for energy.

36. What is released when cells break down sugar for energy?

37. What is released when cells break down sugar for energy? CO 2 and water are released when cells break down energy. It’s the reverse of photosynthesis Oxygen + sugar = CO 2 + H 2 O + energy

38. In what order does food travel through the digestive system?

39. In what order does food travel through the digestive system? Remember: eat soup, sip liquids Esophagus Stomach Small intestine Large intestine (colon)

40. In what order does food travel through the digestive system? Remember: eat soup, sip liquids Esophagus Stomach Small intestine Large intestine (colon)

41. In what order does food travel through the digestive system? Remember: eat soup, sip liquids Esophagus Stomach Small intestine Large intestine (colon)

42. In what order does food travel through the digestive system? Remember: eat soup, sip liquids Esophagus Stomach Small intestine Large intestine (colon)

43. In what order does food travel through the digestive system? Remember: eat soup, sip liquids Esophagus Stomach Small intestine Large intestine (colon)

44. Where does the digestive process begin ?

45. Where does the digestive process begin ? The digestive process begins in the mouth where food is broken up and mixed with saliva.

46. What kind of activities could increase the amount of oxygen in the air?

47. What kind of activities could increase the amount of oxygen in the air? Planting forests and parks could increase the amount of oxygen in the air.
