Colors show the average monthly temperature across each of the 344 climate divisions of the contiguous United States. Climate divisions shown in white or very light colors had average temperatures near 50Â°F. Blue areas on the map were cooler than 50Â°F; the darker the blue, the cooler the average temperature. Orange to red areas were warmer than 50Â°F; the darker the shade, the warmer the monthly average temperature.
Best Answer: In botany, a stoma (also stomate; plural stomata) is a tiny opening or pore, found mostly on the under-surface (epidermis) of a plant leaf, and used for gas exchange.ecause their leaves are held vertically, they have the same number of stomata on the two epidermes. If the plant has floating leaves, there will be no stomata on the lower epidermis and they absorb gases directly from water through the cuticle. If it is a submerged leaf, no stomata will be present on either side.
1 The stomata can close at night when no photosynthesis is taking place, or during the heat of the day when the plant is in danger of too much water evaporating from its leaves. 2  Water-this is absorbed by the roots and sent up to the leaves through the xylem part of the plant's vascular tissue.
