10 Cards in this Set

  • Front
  • Back
describe the process of water dispersal
e.g. the coconut plant; seeds fall onto the ground, high tide washes them away because they are light. washed onto shore where they can germinate again.
What are the three main ways in which pollination can occur?
1: Insect Pollination
2: Wind Pollination
3: Self Pollination
give an example of wind dispersal
the wings of a sycamore
describe the process of SELF POLLINATION
When the pollen of a flower is deposited on its own stigma.
there are two types of animal dispersal, can you describe them?
hooked fruits attach to the animal e.g. burdock and goosegrass. Small hard coated seeds e.g. blakberry and strawberry cannot be digested and pass through the animal undamaged.
describe the process of WIND POLLINATION
many plants do not rely on insects. Their pollen grains are smooth and very light for carrying in the air.
What are the four main types of seed dispersal?
1: WIND DISPERSAL
2: ANIMAL DISPERSAL
3: SELF DISPERSAL
4: WATER DISPERSAL
describe the process of self dispersal
the plant throws seeds some distance from the parent plant e.g. sweet pea
Describe the process of INSECT POLLINATION
insect visits flower yo collect nectar and pollen for food. Some grains attach to insect. The insect visits another flower and transfers the pollen.
what do you call the transfer of pollen from the ANTHER to the STIGMA?
Pollination
