not much. but if you get dirt and germs on them they will turn into blackheads.
Yes, leaf pore is a cell, which is also known as stomata.
Waste exits the paramecium through a structure called the anal pore, located at the posterior end of the cell. This pore allows for the expulsion of unwanted materials and maintains the cell's internal environment.
Pore cell
A cell pore can be compared to a gate or a doorway that regulates the entry and exit of molecules in and out of the cell. Just like how a gate controls access to a fenced area, cell pores control the movement of substances in and out of the cell.
Nuclear pore and availability of carriers
The gaurd cell in the stomata contain chloroplsts and uneven cell wall to create a pore on being turgid.
It all depends on the structure. In cell biology it can be a pore or a stomata.

Depends on what the pore does. If they are channels - they are called Channels. Voltage gated / ligand activated channels. If they are to communicate with neighbouring cells - they are called gap junctions.
The cells found in the excretory system are: one pore cell, one duct cell, one canal cell and a pair of gland cells.
When water flows into the guard cells, they become turgid, causing them to swell and curve away from each other. This opening of the guard cells creates an opening of the stomatal pore, allowing for gas exchange and transpiration to occur.
Small holes in the nuclear membrane of a cell's nucleus, which allow the transportation of water solluable materials in and out of the nucleus through the nuclear membrane.
