3 Use the following information to answer Questions 5 and 6. A red flowering geranium is admired by a visitor at a local garden. The visitor breaks a piece off, takes it home and plants it, and the next season the geranium plant flowers. Question 5 This process A. involves meiosis and mitosis. B. is an example of budding. C. is an example of fission. D. is cloning. Question 6 When the plant flowers, it would be expected that the flowers A. might be any colour, as sexual reproduction occurred. B. would be the same as the parent plant, as they are the product of meiosis. C. would be the same as the parent plant, as they are genetically identical. D. would be different to the parent plant, as they reproduced asexually. Copyright 2016 Neap T5_BioDTTU12_2016.fm 3 / 10
