- Give the advantages and disadvantages of having a dominant gametophyte phase in the life cycle of the Bryophytes.The gametophyte of Pteridophytes is inconspicuous in comparison to the mosses. They are also commonly monecious (single house for male and female gamete production). The photo below shows a whole mount (w.m.) of a fern gametophyte at 4x. Make a sketch of the specimen and label the following structures: archegonium, antheridium, mature gametophyte (prothallus), rhizoids AMooD ok DrDraw a generalized pine tree life cycle and identify the following structures: male and female gametophytes, pollen grain, integuments, archegonium, egg, embryo, and sporophyte.

Which of the following statements describes characteristics of byrophytes that make them dependent on water? State all that numbers that apply. 1. They have a dominant gametophyte phase. 2. They have swimming sperm that need water so they can swim to fertilize the eggs of other nearby plants. 3. They do not have lignin-stiffened vascular tissue or roots to effectively distribute water throughout the plant.
