through cell walls and/or membranes of their cells, usually using aquaporin proteins.
No, transport proteins are also in other organisms.

The endoplasmic reticulum (ER) is a network of membranous tubes and canals within cells that is involved in protein synthesis, folding, and transport. It plays a crucial role in the production of proteins that are either secreted or inserted into cell membranes. The rough ER, with ribosomes attached to its surface, is especially involved in protein synthesis.
Some molecules are too large to pass through the cell membrane without transport proteins.
