Question
Part 4.Phylogeny Summary-Homework Assignment Aggregate fruits form from several to many separate pistils in a single flower. The pistls may be sunken into the receptade or scattered over the surface as in strawbemies blackbermies and raspberries (Figure 5-35) Multiple fruits form when the ovaries of two or more flowers combine into a mass such pineapple fruits (Figure 5-35) Prelab Assignment:Bring 5 dftlerent fungal examples to dlass next week Put in labeled ziplock bag with your name, location/habitat collected and date collected It is easy to get lost in the details. Your homework assignment is to use the information from the last two labs to complete Table 5-5 and a cladogram chanting the evolutionary relationships of the top taxa esxamined over the last two weeks. A set of character states is ksted in Table 5-5 as in mulberry, fig or Figure 5-35. Aggregate and multiple fruits The outgroup information has been entered 1. Complete the data set for the ingroup character states Aggregate fruit Multiple fruit (pineapple) Designate a value of "o' if an ingroup character stae matches the outgroup character state. Enter a"I it the character state is different from the outgroup. You will use these designations to complete the phylogeny Ilustrated in Figure 5-36 Single truit Table 5-5·Character stone toble for land plants.
