- 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.

- (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.
