Down 1. Solute concentration greater outside the cell than inside so water moves out of the cell 2. Active transport pump that helps move materials from low to high concentrations 3. Passive transport from an area of high to an area of low concentration 5. Type of active transport that moves large particles into a cell through vesicles 7. Vacuoles that help one-celled organisms pump out excess water 9. The difference in the concentration of molecules across a distance 11. Cells bursting from excess water pressure inside them 13. Proteins used during facilitated diffusion 14. Cell eating 16. Transport that doesn't require energy
