1. Is the flower in Figure 5-1 hermaphroditic, monoecious, or dioecious? Explain how
you know. Is it a magnoliid, a monocot, or a eudicot? Explain how
you know.
2. Looking at the tree in Figure 5-3, which of the three groups in Table 5-1 would you
guess are most closely related?
3. Using Table 5-1, name an apomorphy in the magnoliids, monocots, or eudicots.
Using just the information in the table can you name any synapomorphies? If so,
name one and what groups share it. If not, explain why you cannot. Using just the
information in the table can you name any symplesiomorphies? If so, name one
and what groups share it. If not, explain why you cannot.
4. Using Figure 5-3 as a guide, draw a phylogeny of just the magnoliids, monocots,
and eudicots. Make tick marks on your tree labeling the origin of three apomor-
phies from Table 5-1 (there are more than three present). You may use any three
apomorphies, so long as you have tick marks on multiple branches of the tree.
5. Bring your dissection kits! If you want to wear gloves while using the toluidine blue
stain, you must provide them. If you have allergies to pollen, consider taking an
antihistamine before lab this week.

portion is called the pedicel, and the point where the pedicel becomes the flower is
called the receptacle. In most flowers, the receptacle is situated below up to four rings
of flower parts of one type. Each of these rings is called a whorl. The lowest two whorls
are nonreproductive-the sepals and the petals (together called the perianth). The
perianth attaches below the two reproductive whorls of stamens and carpels.
