33. Question 4 - 10 The asexual reproduction of a single-celled organism by division into two roughly equal parts is called _______________

34. Answer 4 – 10 Binary Fission

35. Question 4 - 20 _____________ is the creation of offspring from a single parent and does not involve the joining of gametes.

36. Answer 4 – 20 Asexual reproduction

37. Question 4 - 30 In the process of _____________ a small projection grows on the surface of a parent organism and eventually forms a separate new individual

38. Answer 4 – 30 Budding

39. Question 4 - 40 In general, ______________ reproduction involves the modification of a stem or underground root structures of the parent organism.

40. Answer 4 – 40 Vegetative

41. Question 4 - 50 Explain how Mitosis and Cytokinesis differ from Binary Fission

42. Answer 4 – 50 In Mitosis there are chromosomes and a nucleus that divide. It is only cell division, not reproduction. In Binary fission a new organism is produced
