The cuticle also works with the stomata to help complete photosynthesis. After the stomata open and carbon dioxide enters the leaf, the cuticle protects the mesophyll layer, which contains the photosynthetic cells that receive and process the carbon dioxide to manufacture glucose. The cuticle is translucent, so it does not block the sunâs rays from reaching the photosynthetic cells.
Cellphone GSM Frequencies: 900/1800. (This means you will need a GSM cellphone that will work on 900MHz or 1800Mhz to use it in Iran.).
Wireless home phones Â­broadcast at 900 MHz, 1.9 GHz, 2.4 GHz and 5 GHz. FM radio spans from 87.5 MHz to 108 MHz. Many routers, along with all Bluetooth devices, Â­transmit at 2.4 GHz. And with so many gadgets hanging around in such a Â­narrow range of frequencies, things can get crowded. Signals can get crossed, literally.
