Sometimes, some of these large molecules are transported across the cell membranes by carrier proteins; this does not require energy and as a result is a form of passive transport. There are three types of passive transport: simple diffusion, osmosis, and facilitated diffusion.

Hints: With diffusion, solutes move from an area of high concentration to an area of low concentration. With Osmosis, wherever more salt is, water follows! Or, water also goes from an area of high amount of water to an area of low amount of water.

Osmosis is the movement of a liquid or other solvent (generally water) through a semipermeable membrane. In this process, the liquid/solvent moves from an area where the solute concentration is low to an area where the solute concentration is higher.
Teacher’s Guide & Answer Key Learning Objectives: After completing the activity the students should be able to: 1. Define and understand the term osmosis. 2. Understand that both the random movement of water molecules and concentration gradient help maintain water balance across cell membranes. 3.

This document is an osmosis worksheet answer key that provides information about the direction of water movement between animal cells placed in solutions of different concentrations. It identifies whether solutions are hypertonic, hypotonic, or isotonic based on the water and solute percentages, and indicates whether water will move into or out ...
