Petals Attract Insects
Sepals protects the bud till it opens
stem supports the flower and provides water/nutrients
Anther Produces the pollen grains. When the grains are fully grown, the anther splits opens
Filament Supports the anther
stigma the sticky part on top the style that collects the pollen
Style Supports the Stigma
ovary contains the ovules (eggs) where the fertilization occurs. The hollow structure at the base of a pistil that protects seeds as they develop
ovules (eggs) Once fertilized it becomes the seed
Pollination The transfer of pollen from the anther to the stigma of the same species by pollenators
pollenators insects (bees, wasps, some flies and butterflies) and some birds
How a flower is pollinated when a pollen grain lands on its stigma
Annual life cycle in one year
Biennial life cycle complete in two years
perennial life cycle complete in over two years
Perfect flower both stamen and pistil
Imperfect flower either stamen or pistil
Composite Many perfect flower
Life cycle Seeds, Germination, Stems and Roots, Leaves, Flowers, and Pollination
Cross-Pollination occurs when pollen is carried from one plant to another of the same species.
Hybrid Plants are cross-pollinated to achieve specific features
Four main parts of a flower Sepals, petals, stamen, and pistil
Critical night length the number of hours of darkness that determines whether or not a plant will flower
auxin a hormone that controls a plant's response to light
short-day plant a plant that flowers when the nights are longer than a critical length
long-day plant a plant that flowers when the nights are shorter than a critical length
hormone a chemical that affects the growth and development of a plant
day-neutral plant a plant whose flowering cycle is not sensitive to periods of light and dark
tropism a plant's growth response toward or away from a stimulus
thigmotropism a plant's response to touch
seed dispersal the scattering of seeds
Root cap protects the root as it grows through the soil
