The functions of rhizoids are root-like structures that absorb water and transport materials to the plants. The position of the archegonium and antheridium relates to their reproductive function by having the archegonium located under the eggs so that when the antheridium sperm is dispersed, it can reach the egg better. Antheridium is upright so that the sperm can be dispersed on top and reach the archegonium egg to fertilize the plant. They are also located near each other so that when there is
characteristics. Using this information about different divisions within kingdom Plantae and our observations of the mystery spores, we created a phylogenetic analysis comparing the mystery spores with the following divisions: Chlorophyta (green algae), Marchantiophyta (liverworts), Bryophyta (mosses), and Pteryophyta (ferns). According to this analysis, we concluded that the mystery spores belonged to the division Pteryophyta. 2. Introduction The mystery spore lab challenged us to identify what division
