Cell Membrane Transport Hypertonic Hypotonic Isotonic

Movement of a substance across a cell membrane against its concentration gradient from lower concentration to higher concentration. Energy required.

• osmosis

• diffusion

• facilitated diffusion

• active transport

Concentration (amount) of solutes OUTSIDE of the cell membrane is LESS than inside the cell; this promotes a greater flow of water inside the cell thus leading to cell bursting.

• solvent solution

• isotonic solution

• hypertonic solution

• hypotonic solution

Movement of very large molecules (into the cell) across the cell membrane through the fusion of vesicles. Energy required.

• diffusion

• endocytosis

• exocytosis

• osmosis

After examining this diagram showing the concentration of water inside and outside of the cell, identify the tonicity of the solution.

• hypertonic

• hypotonic

• isotonic

The solution surrounding the cell in Diagram B, would be defined as:

• hypertonic

• hypotonic

• isotonic

After examining this diagram showing the concentration of water inside and outside of the cell, identify the tonicity of the solution.

• isotonic

• hypotonic

• hypertonic

What type of solution allows water to enter the plant cell?

• hypotonic solution

• hypertonic solution

• isotonic solution

• active transport

Nemo and other ocean dwelling fish cannot survive in freshwater because......

• freshwater is hypertonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypotonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypertonic to Nemo's cells and will result in water entering them causing the cells to swell and burst

• freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst
