trees, shrubs, and some herbs
9
How many flowering parts does a monocot have and how many does a eudicot have
monocot: in threes
eudicot: in fours or fives
10
What type of pollen part does a monocot have and what type does a eudicot have
monocot: monoaperturate
eudicot: triaperturate
11

monocot: one
eudicot: two
12
What is the leaf venation like on a monocot and what is it like on a eudicot
monocot: parallel
eudicot: netlike
13
How are the primary vascular bundles in the stem arranged in a monocot and eudicot
monocot: complex arrangement
eudicot: in a ring
14

monocot: rare
eudicot: commonly present
15

3000 species
18
What is unique about myco-heterotrophs
they have obligate relationships with mycorrhizal fungi and lack chlorophyll
19
What are the specialized organs that parasitic plants have
haustoria, they penetrate tissues of their hosts
20

what are sporophylls commonly called
leaves
22
How does the determinate stem differ from the other stems
it stops growing once it bears a flower
23
What classifies a plant as a peduncle
if it has one flower
24
What are the male parts on the flower
the stamen which includes the anther and the filament
25
What are the female parts on the flower
the carpel and that contains the ovary
26
What are inflorescences
aggregation of flowers
27
What is the peduncle
the main flower stalk
28
What is the pedicel
