This set includes the following cards:
PhotoperiodismResponse of an organism to seasonal changes in day length
Day-neutral PlantsA plant that flowers regardless of the length of the period of light it is exposed to
FlorigenPlant hormone that promotes flowering
AestivationThe arrangement of petals and sepals in a flower bud before it opens
DiapauseA temporary pause in the growth and development of an organism due to adverse environmental conditions
AnnualsA plant that completes its life cycle within one year
AbscissionThe natural detachment of parts of a plant eg. dead leaves, ripe fruit
DormancyA period in an organism's life cycle when growth & development are temporarily stopped
BiennialsHaving a life cycle that takes 2 years to complete
PerennialsA plant that lives for more than 2 years
Over-winteringTo pass, spend, or survive the winter
EphemeralsShort-lived (lives for one day)
TropismGrowth responses to directional stimuli
TaxesWhole body responses to directional stimuli
NasticNastic movements are rapid responses to non-directional stimuli
