What is a perfect flower?
A perfect flower has both female and male parts, that is, both pistils and stamens.
What happens during self-pollination?
The pollen is transfered from an anther to a stigma in the same flower.
What is seed dispersal?
Seed dispersal is when a seed moves from the flower to a place where it can sprout.
What is germination?
Germination is what happens when a seed actually sprouts. The right conditions will allow a seed to germinate.
Give three examples of how seeds are dispersed?
Through wind, water and animals
Explain how seeds are produced.
A pollen grain is transferred from the anther to the stigma. On the stigma, a tube forms from the pollen grain to the ovary. A sperm travels down the tube and fertilizes the egg cell. A seed develops from the fertilized egg cell.
What is vegetative propagation?
When you grow new plants from pieces of a plant that already exists--such as a stem, a leaf or a root, rather than from seeds.
Describe the difference between fertilization and germination?
In fertilization, a sperm cell combines with an egg cell; in germination, a fertilized seed sprouts.
