The word comes from gymno-, meaning "naked," and -wsperm, which refers to "seeds" not actual sperm. Gymnosperms have "naked seeds," because they do not encase their seeds in fruits as do angiosperms. 1. Gymnosperms were also the first plants to develop pollen. Which of the following statements correctly describes one of the advantages of pollen? The development of pollen means that gymnosperms no longer require sporophytes for reproduction. The development of pollen means that gymnosperms are not dependent on water for reproduction. Pollen is created by the sperm of the plant. 2. In gymnosperms, where are the female gametophytes located? In the ovulate cones The gametophyte stage no longer exists in gymnosperms In the needles or leaves 3. Although they are no longer the dominant group of plants on Earth, gymnosperms play an important role in our lives. For example, much of the lumber used in construction comes from conifer species such as pine, fir, and redwood trees.
