A minute opening in a surface, esp. the skin or integument of an organism, through which gases, liquids, or microscopic particles can pass
any tiny hole admitting passage of a liquid (fluid or gas)
concentrate: direct one's attention on something; "Please focus on your studies and not on your hobbies"
any small opening in the skin or outer surface of an animal
stoma: a minute epidermal pore in a leaf or stem through which gases and water vapor can pass
(porous) able to absorb fluids; "the partly porous walls of our digestive system"; "compacting the soil to make it less porous"
(porous) full of pores or vessels or holes
(Porous) Porosity is a measure of the void spaces in a material, and is a fraction of the volume of voids over the total volume, between 0–1, or as a percentage between 0–100%. ...
a tiny opening in the skin; by extension any small opening or interstice, especially one of many or allowing passage of a fluid; to study meticulously; to go over again and again; to meditate or reflect in a steady way
(porous) Full of tiny pores that allow fluids or gasses to pass through; : full of loopholes; With many gaps
(pores) Wood cells of comparatively large diameter that have open ends and are set one above the other to form continuous tubes. The openings of the vessels on the surface of a piece of wood are referred to as pores.
(Pores) Cell-like cavities that characterize the grain of the wood.
(Pores) Minute orifices in wood.
(Pores) The microscopic openings in the anodized surface. The pore opening leads to a microscopic tube. Although porous, the anodized surface is very dense and hard. The number (or pore density) and size of the pores are dependent on the process conditions used.
(Pores) The space between soil particles, which can be filled with water or air. A porous soil has lots of pores.
(Pores) are the minute or microscopic voids in porous rock. Rocks containing pores are able to hold oil, gas and water. If the pores are interconnected, the rock is permeable and a good reservoir rock.
(Pores) openings in the theca that can be involved in the extrusion of certain structures from the cell; genetically variable and used for identification of species; also known as trichocyst pores
(Pores) small openings between grains in rocks.
(porous) Having a granular surface as the result of oxidation.
(porous) A description indicating a rough or granular surface, typically seen on pre-1816 copper coins.
(porous) something which allows water to pass through it. Compare nonporous.
(porous) Having small passages; permeable by fluids.
(Porous) Materials ability to absorb water having many small openings.
(porous) The ability for paper to allow air to permeate and ink to penetrate. The more porous the paper, the higher the capability for ink penetration.
(Porous) A material is said to be porous when it has several minute holes and is permeable to liquids.
(Porous) A surface that was many tiny openings. A porous surface will require more finish or sealer to fill and smooth out these openings.
