Diploid multicellular individual Exercise I Marchantiophyta: The Liverworts Examine with the dissecting microscope the thalli of the relatively large, dichotomously branching gametophytes of Marchantia 1. Are these thalli the gametopytes or sporophytes? 2. Are the thalli haploid or diploid? 3. Are any gemma cups containing gemmae present on your plant? 4. What is the function of gemmae?

Examine carefully with the dissecting microscope the additional liverworts that are
available. Note the dichotomous branching, the midrib-like region, and the air pores on the
upper (dorsal) surface.
5. How is dichotomous branching different from the branching pattern seen in higher
plants?
