But you'll always start in the Bluetooth settings. First, launch the iPad's settings. On the left-side menu, find and tap Bluetooth.. If Bluetooth is off, you can turn it on by tapping the on/off switch. It may take a few seconds for your iPad to discover the wireless keyboard. When it appears in the list, simply tap it. If it requires you to input a code, the iPad will display a code onscreen that you can enter on the keyboard.
Pollen is produced in the 'microsporangium' (contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants).
Pollination takes place immediately before the anthesis. Anthers elevate by elongating the stamen filaments, and untimately they go out the spikelet during anthesis. When anthers touch stigma, some pollen are left on the stigma. The stigma can receive pollen also during the flowering, when the spikelet opens.
