3.3a Insect Pollination

• In the process of pollinating of flower, there must be a transferred of pollen grains from the anther of one plant to the stigma of another.
• Pollen is the small structure which contain the male nucleus and the transferred in an insect pollinated plant is take places by insects.
• So, its necessary for this type of flower to attract insect into the first flower and then have a reason to go to the second flower. If pollen goes to one plant to another we called it cross-pollination.
• Looking the single flower structure we found the adaptations to attract the insect, first of all we  might call signals which is in the inside which is colour petals, insect can see colours.
• Second thing are scents which flowers has which attract the insect so, insect can detect these molecules and be attract by the plants from the scents.
• A value to the inside of going into the flower which provide food which at the nectaries is producing a sugar called fructose, many insect will use the pollen itself to as a source of protein and the stamen is the male part of the plant and compose to the anther which is produce pollen grains and their on the stalk called the filament.
• So, the anther and the filament form the stamen and then the female is compose of 3 sections which are the stigma which pollen grains fall, style which connects to the stigma to the ovary which we can find the eggs called the ovules and this whole structure here is called a carpel that the female part and the stamen of the stamen.
