3.3a Insect Pollination


+ The porcess of pollinating is where pollen from an Anther is transfered to another plants Stigma, this is done by insects.
+ Pollen contains male nuclei.
+ Plant -> Plant = cross polination.
+ For this process to happen the insect needs to be attracted : -Signals - coloured petals
                                                                                              -Scents
                                                                                              -Value for Insect = food, Necaries produce Fructose -> Pollen protein.
+ Parts of a plant: Male = Stamen : Anther, Filaments
                            Female= Carpel: Style (which connects) stigma, ovary - ovules
