The endoplasmic reticulum are transport tubes made of membrane that move proteins and other materials through the cell, most likely sending them towards the Golgi apparatus/body.
They are used in Facilitated Diffusion, helping to transport ions, macromolecules, and other substances incapable of entering a cell by themselves to cross through the plasma membrane of the cell.
Endocytosis Lol you go to IHS? Re: Lol, I'm just googling the questions for Mr. Elliott's homework, let's see. Bulk transport of substances out of the cell.. LOL im in IHS 2 im in Mr. elliotts class 2, did u guys graduate, and i wanna ask lower concentration of solutes outside the cell than inside, what is its prefix
When particles diffuse they break apart, down into simpler substances. Diffusion is the net movement of molecules from high to low concentration through random motion. From the particle point of view it just moves about at random (as usual) but the overall effect is for the particles to spread out evenly.
Water moves across the cell membrane through the process of osmosis.

The endoplasmic reticulum moves substances through the cell within channels made of membranes. The cytoplasm also moves substances and organelles through cytoplasmic streaming

The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
