3.  (6)  There are two characteristics that are diagnostic of the 
Caryophyllales.  The first is a seed characteristic that occurs in all 
members of the family where the"                " surrounds the 
"               ".  The second concerns floral pigments, most families 
of flowering plants produce "               "while most members of the 
Caryophyllales produce "             ".  Two families in the Caryophyllales, 
the "             "and the "                ", do not produce the floral 
pigment compounds found in all the other families in the Caryophyllales.

9.  (5)  The fruit in the Brassicaceae is either a "               " or 
a "           ", which are modified "              "that dehisce (split) 
by "               "and have a "            "to which the ovules are 
attached.

You can use either common or scientific names.

A.

B.

11.  (2) There are several families of insectivorous plants and they 
tend to occur in the same kind of habitat.  What is this habitat type 
"            "?  Why have these plants developed these special 
adaptations that allow them to trap insects?

the genus Primula?

B.

C.

13.  (4)  What is a common narcotic that is obtained from a member of 
the Papaveraceae "             "?  This compound is extracted from a 
latex exudate called "           ".  When was the first time that 
addiction to this drug became a serious problem in the U.S.A. 
"              "?  This narcotic can be chemically modified to form a 
more potent and addictive compound called "                ". 

14.  (2)  Many plants produce compounds that are long chain 
hydrocarbons.  What are these compounds called "               " and 
how could you determine their presence "                 "?

15.  (6)  Indicate which plant is a member of the Ranunculaceae and 
which is a member of the Caryophyllaceae.  Give 2 contrasting features 
of each which will allow you to tell them apart.

18.  (2)  In terms of their morphology, flowers in the Ericaceae can be 
either "                   " or "                  ".

19.  (2)  Members of the genus Viola often produce two types of flowers,

zygomorphic), a corona is present and consists of one or more rows of 
(petals, stamens, bracts, filaments).  The anthers are (monadelphous, 
basifixed, versatile).  One group of insects that are commonly feed on

22.  (2)  The inner bark of the genus "             " was used by 
Native Americans to treat headaches.  We use a synthetic derivative 
of this called "                   " for the same purpose.
