Abscisic Acid
Produces pollen grains
Anther
Affect many aspects of plant growth and development. also apical dominace in plants
Auxins
Female portion of the flower
Carpel
Flowers that have sepals,petals,stamens,and carpels
Complete Flowers
Fruits that develop from several individual ovaries
Compound Fruit
Pollen is from a different plant
Cross Pollenation
A plant that has staminate and carpellate flowers on separate plants
dioecious plants
One sperm nucleus unites with the egg nucleus, producing a zygote
Double fertilization
promote cell division. prevent senescene and initiate growth
Cytokines
the protoplasmic tube that is extruded from a germinating pollen grain and grows toward the ovule.
Pollen tube
the fertilized, matured ovule of a flowering plant, containing an embryo or rudimentary plant.
Seed
the transfer of pollen from the anther to the stigma of the same flower, another flower on the same plant, or the flower of a plant of the same clone.
Self-pollination
one of the individual leaves or parts of the calyx of a flower.
Sepals
a fruit formed from one pistil.
Simple fruits
the form of a plant in the alternation of generations that produces asexual spores.
Sporophyte
the pollen-bearing organ of a flower, consisting of the filament and the anther.
Stamens
the part of a pistil that receives the pollen.
Stigma
The usually slender part of a pistil, situated between the ovary and the stigma.
Style
oriented growth of an organism in response to mechanical contact, as a plant tendril coiling around a string support.
Thigmotropism
