Water and salt, both inside and out of the cell.
The only substance that carries out osmosis is water. Osmosis is the movement of water through a semi-permeable membrane from a low concentration of solute to a high concentration of solute in the pursuit of equilibrium across the membrane.
The definition of osmosis does not restrict this phenomenon to any single substance. I don't know where you would get that idea. In practice, most of the situations involving osmosis, that are of interest to us, take place in an aqueous medium. But osmosis can occur in other media.
Osmosis is a specific type of diffusion that involves the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. Water is the only substance that carries out osmosis due to its ability to move freely through the membrane.
osmosis
yes it carries the waste substances and the food substances the waste substance that it carries is urea
Osmosis and diffusion
Blood carries necessary substances to various parts of the body.
Only water is transported through the process of osmosis.
