if you are talking about parts, nothing.
but sugar and salts enter the cell. Water does too.(osmosis)
The water enters the leaf by ascent of sap. It is used in photosythesis. It reappears or synthesized during respiration and ultimately leaves through stomata by transpiration.
Water enters the root cells by osmosis and enters into the xylem. The pressure of water entering the xylem creates osmotic pressure, pushing the column of water up through the stem. Water evaporating on the surface of the leaf cells pulls on other molecules and pulls the column of water up the plant and into the leaves.
The chloroplasts in the leaves absorb the light directly from the sun. The carbon dioxide goes into the leaves through the stomata (tiny holes on the bottom of a leaf) and is diffused through the rest of the cells. The water is absorbed by the roots then carried by the xylem up to the leaf and the cells in the leaf.
It's the cell membrane that controls when enters and leaves a cell.
Carbon dioxide is produced inside all the cells of the body, as a metabolic by-product. Carbon dioxide does not enter through the lungs, rather, it leaves through the lungs.

Water moves between cells by osmosis, down a concentration gradient.
