Dioecious plants
A
- Each plant has its own sex
* Ex: persimmon, ginko, holly
5
Q
Monoecious plants
A
- Has both sexes on the same plant but in different locations to increase chance of genetic diversity
- Ex: birch trees, oaks, corn, begonias
- Some plants’ sexes are ready at different times
6
Q
Peduncle
A
stalk that holds the flower (like the petiole to a leaf)

8
Q
Receptacle
A
area of flower attachment
9
Q
Sepal (calyx plural)
A
- protection, when cover the flower bud
- functions for attraction (sometimes); can become colorful and look like petals
- ex: cover the bud, like leaves at top of strawberry or bottom of apple

11
Q
Petal (corolla plural)
A
- main function is attraction (color and scent)
* protection (shape that can hinder some insects and permit certain others)
12
Q
Stamens
A
- male structure, in 2 parts: filament and anther
13
Q
Pistil
A
- female structure, in 4 parts: stigma, style, ovary, ovules
14
Q
Anther
A
produces and distributes pollen
15
Q
Pollen grains
A
sperm
16
Q
Pistil
A

17
Q
Stigma
A
receptacle, receives pollen; sticky or wet, pubescent are possible attributes
18
Q
Style
A
- connects the stigma to the ovary
- has to put the stigma in exactly the right place to be effective
- sperm travels through to the ovary
19
Q
Ovary
A
- contains ovules
* becomes fruit

62
sexual reproduction
union of gametes (sperm and egg)
63
gymnosperms
* relates to seeds; literally "naked seed"
* main group of plants before dinosaurs
* seed does not have an ovary covering
* ex: pine, spruce, ginko, cycads
* do not have flowers, though have other reproductive structures
64
ferns
have own reproduction process different from gymnosperms and angiosperms
65
monocot flowers
have flower parts in 3's or multiples of 3's
66
dicot flowers
have flower parts in 4's or 5's of their mulitples
67
flowers
purpose is to produce seed(s)
68
imperfect flower
contains one sex only (stamen or pistil)
69
complete flower
has sepals, petals, stamen, and pistil
70
incomplete flower
missing one or more of sepals, petals, stamen, or pistil
71
perfect flower
has both sexes (stamen and pistil)
72
imperfect flower
contains one sex only
73
staminate flower
a male imperfect flower
74
pistilate flower
a female imperfect flower
75
angiosperms
* have a covered seed
* monocots and dicots
* vegetables, trees (except conifers)
76
ferns
have own reproduction process different from gymnosperms and angiosperms
