insect pollination:
- Insects attracted to petals and nectar.
- Insect enters flower and pollen is transferred from Anther to Insect.
- Insect is attracted to another flower.
- Pollen from Insect is transferred to Stigma.
- Pollen cell grows a pollen tube down the Style to the Ovary. |
|
How can an insect pollinator transfer pollen from one flower to another? |
|
|
|
Fertilisation occurs when the Pollen nucleus fuses with the Ovule.
The fertilised Ovule forms the seed.
The Ovary forms the Fruit. |
|
What happens to cause fertilisation in a flower? |
|
|
| T |
The function of Pollen cells are to transfer genetic material (DNA) from one plant to another. |
|
What is the role of a pollen cell? |
|
|
| W |
Pollen cells are adapted to their function by:
- being small (microscopic)
- having a tough outer coating
- can have spikes or hooks |
|
How are pollen cells adapted - Give at least 2 ways. |
|
|
|
Pollen being small allows it to be transported easily by insects (and wind next lesson)
Pollen having a tough outer coating allows the cell to survive in the environment away from the plant.
Pollen have spikes or hooks makes it more likely to stick to insects. |
|
Why does pollen have a tough outer coating? Why do some pollens have spikes or hooks on them? |
