Section A
You are provided with specimen C , D and E. (a) Observe the displayed reproduction system in the dissected specimen C and then answer the following questions; (i) What is a sex of the specimen C ? Give a reason to support your answer. (ii) Draw a well labelled diagram of the reproductive system observed in dissected specimen C . (b) Carefully use the hand lens to observe the structures used for reproduction in specimen D and then draw a diagram of a frond with its reproductive structures. (c) What are types of reproduction exhibited by specimen D and E? Give a reason on each to support your answer. (d) Briefly explain how the type of reproduction in specimens D and E occurs. (e) In what ways are specimens D and E useful to human being. Give two points for each.
