Explanation / Answer

33. b. ATP or any other high energy molecule facilitates transport via expending high energy phosphate group.

34. a. Flagella is larger as compared to cilia which are small hair-like projections.

35. a. Rough ER is involved in producing proteins

36. b. smooth ER is involved in making carbs and lipids, Rough ER is involved in protein synthesis.

37. c. Golgi apparatus is the organelle which sort and transport proteins from ER using vesicles derived from its membranes.

38. b. vesicles are derived from Golgi apparatus and are involved in protein sorting and transporting.

39. b. vesicles are used for transport whereas, lysosomes are involved in digesting cell debris, foreign substance, cells.

40. b. hydrothermal vents- are associated with early cell origin providing the right temperature and condition for the origin of the cell.
