proteins
The special structures in the cell membrane that allow materials like water and sugar to pass through are proteins called transport proteins. These proteins help facilitate the movement of specific molecules across the membrane by acting as channels or carriers. They play a crucial role in regulating the flow of substances in and out of the cell.
Special doorways in the cell membrane are made of proteins called ion channels or transporters. These proteins allow specific ions or molecules to pass through the cell membrane, regulating the movement of substances in and out of the cell.
Permeable if anything can go through or semipermeable if only certain things can go through it.
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
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.
Membrane transporter.

The cell membrane is the special structure that allows materials to pass through, utilizing channels and transport proteins to facilitate the movement of water and sugars in and out of the cell. This selective permeability helps regulate the internal environment of the cell and maintain homeostasis.

The nuclear pores are tiny holes in the the nuclear membrane surrounding the nucleus of a cell, which allow the movement of solluable materials through the nuclear membrane, in and out of the nucleus.
