1) Examine a diagram showing the life cycle of a fern. Does the fern have alternation of generations? Explain. What stage of the life cycle is the typical, spore-producing, mature fern plant? Which stage of the life cycle is dominant in the ferns?

2) Does the fern have true roots, stems, and leaves? Explain. What makes these structures “true”?

3) The fern stem is called a rhizome. What is the definition of this structure? The fern rhizome is found underground where we would normally find roots. However, it is considered to be a stem. Explain.

4) What is the term for a fern leaf? The fern leaf is divided into individual leaflets that are arranged along the sides of a common axis. What term is used to describe this? Using the diagram of the parts of a fern, Identify the parts of a fern leaf including stipe, rachis, pinna, and blade.
