- The egg and sperm producing strcutures of pteridophytes are found on the gametophyte, also called theByrophytes 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.Which of the following processes occurs in a plant's sexual life cycle? sporophytes produce gametes by meiosis sporophytes produce gametes by mitosis gametophytes produce gametes by meiosis gametophytes produce gametes by mitosis
