Dispersal Flashcards
is not part of the plant structural development,
but without _________ , the young plant will not be able to
separate itself from the parent plant
Dispersal
an essential part of the plants life cycle.
Dispersal
❑Through Dispersal plants learned to adapt to their agents
and agents adapted to the plants ; this mutualistic
relationship is called ________
Co-evolution
❑The first form of dispersal is within the pre syngamy stage:
______
POLLINATION
leads to FERTILIZATION
POLLINATION
Process when flower from the same plant pollinates another flower,
as well as when a flower pollinates its own self.
SELF POLINATION
❑Process wherein agents or intermediates carry pollen from one flower of a plant to another flower of another plant.
cross polination
True or False: This crossing over of genes from different plants is the very goal of sexual reproduction in plants through flower, seeds and fruits.
true
depend on the wind for
pollination , showy petals are not really required
ANEMOPHYLLOUS FLOWER
depend on animals for
pollination
Zoophyllous flower
depends on insects for
pollination
Enterophyllous flower
seeds dispersed by its own fruit.
