We now class tellurium as a metalloid because, as the confused scientists of the 1700s first noticed, it has properties that sit between those of metals and nonmetals. Hubble Telescope Wide Field Camera 3.
Water also easily enters the lymphatic capillaries via gaps between the lymphatic endothelial cells. These gaps function also as flap valves and this also promotes forward lymph flow when the capillaries are compressed. In other areas of the body the water permeability of capillary membranes is quite low.
The cells of plants, fungi, and most chromalveolates have a cell wall, a layer outside the cell membrane, providing the cell with structural support, protection, and a filtering mechanism. The cell wall also prevents over-expansion when water enters the cell.
