Lily Dissection

Adaptation -structure enables function

Example 1: Lily Flower

• Sepal (the outermost layer) has been mutated so that it looks like petals to attract insects because of its colours.
• Petals has line guiding the insects toward the nectar source.

Example 2: Grass

• They're relying on wind for pollination so they don't have to waste the energy to attract insect.
• Plants relying on wind pollination would produce far more pollens to increase the chance of the pollens falling into the stigma of another plant.

Remember - vector for pollination: wind and insects

Additional knowledge: 

• It is possible for plants to self-pollinated but they try to avoid this because the offspring would be exactly the same as themselves.
• It is also possible for different plant species to cross-pollinated. The offspring is called hybrid. However, a hybrid would never produce pollen for further reproduction.
