Flower Structure & Cross-Pollination
Stamen and Style Maturation Times
Restrains self-pollination
Cross-Pollination
pollen comes from another individual
Stigma and Pollen Incompatibility
Another self pollination preventer
crop species
Monoecious & Dioecious
Lack Essential Organs
imperfect flowers and incomplete flowers
Dio
Only one or the other
Mono
Both Stamenate and carpellate flowers
Animal Pollinated Flowers
Coevolution
mirror images
actinomorphic
zygomorphic
Forces pollinators to feed next to pollen

Egg
Mega sized
Sperm
Microsized
Can fuse with each other to form diploid
Syngamy
Spore
Can't Syngamize
Gametophytes
Heteromorphic generation
Two halves of a generation do not resemble from the origin of the gametophyte
Fertilization
karyogamy
fusion of the nuclei
plasmogamy
fusion of the protoplasts
Double Fert.
Sperm fuses with egg and polar nuclei
