3.3a Insect Pollination

Key Points:

1. In the process of pollinating, there has to be a transfer of pollen from the anthers to the stigma of the flower
2. Pollen contains the male nuclei
3. The pollination takes place from insects, and the flower has to attract the insect
4. If pollen goes from one plant to another, its called cross pollination
5. The adaptations to attract the insect have signals such as colour of petals, scents which attract insects, and a pay off or value of the insect going to the flower which is given as a food in the nectaries producing a sugar called fructose
6. Stamen is the male part of the plant, composing of an anther which produces pollen, and is on a filament
7. The female part consists of a stigma in which the pollen falls on, and the style connects the stigma to the ovary, which contains the eggs and these are called ovules. The whole structure is called the Carpel
