The calyptra buds to form a mature gametophyte. The zygote is housed in the venter.The gametophyte of Pteridophytes is inconspicuous in comparison to the mosses. They are also commonly monecious (single "house", or thallus for male and female gamete production). The photo below shows a whole mount (w.m.) of a fern gametophyte at 40x. Make a sketch of the specimen and label the following structures: archegonium, antheridium, mature gametophyte (a.k.a. prothallus), rhizoids 90Byrophytes are usually found in areas that are very wet or damp at least part of the year. 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.
