So the carbon dioxide comes in through the stomata, makes it's way through gaps in the airy layer of cells (called spongy mesophyll) at the bottom part of the leaf, then heads up to the palisade layer for photosynthesis.
The streets were almost deserted, except in the vicinity of the temple, which they only reached after having traversed several quarters surrounded by palisades.
It was common for towns to develop around these castles, as inhabitants benefited from the protection offered by the moats, raised earthworks, and wooden palisades.
I put out my hand to feel the dark mass before me: I discriminated the rough stones of a low wall—above it, something like palisades, and within, a high and prickly hedge.
Because once you dig the ditch around it, put up the palisade wall, put a garrison in there, it becomes very hard for anyone on the Danish side to retake it.
