1. When a solution has more solutes outside a cell then the solution is said to be ___________________. 2. Macrophages engulf debris and microbes utilizing a process called ____________________________. 3. Steady internal, physical, and chemical conditions such as ion and fluid balance. _________________ 4. Solutes move from an area of high concentration to low concentration in a process called ___________________. 5. The plasma membrane allows some material into and out of the cell and excludes other solutes. The term to describe this property is _______________________. 6. Movement of water from an area of low solute concentration to an area high solute concentration across a membrane is called __________________.

Step 1
Step 1: hypertonic — A solution with a higher solute concentration outside the cell than inside is called hypertonic; water tends to move out of the cell causing it to shrink. Show more…

a. Brownian motion b. Diffusion c. Filtration d. Hydrostatic pressure e. Hyperosmotic f. Hypoosmotic g. Isosmotic h. Osmosis i. Semipermeable 1. When compared with the cell's fluid, solution X has a higher impermeant solute concentration. 2. When compared with solution Z, the cell has a lower impermeant solute concentration. 3. The movement of water from an area of lower impermeant solute concentration to an area of higher impermeant solute concentration is an example of osmosis. 4. Dye particles spread evenly through water. 5. Starch particles do not pass through a paper membrane. 6. A cell uses energy to "pump" sugar molecules from its external environment. 7. Water in the cell moves out into a concentrated salt solution bathing the cell.
1. Molecules tend to move from areas of ______________ to areas of _______________. (select all that are correct). a. low pressure; high pressure b. low concentration; high concentration c. high concentration; low concentration d. high pressure; low pressure 2. How do cells maintain a state of homeostasis? a. By a constant exchange between intracellular and extracellular environments b. By controlling the extracellular environment to create optimal conditions c. By not letting molecules enter the plasma membrane d. By regulating the amount of water that enters and exits the plasma membrane 3. What does membrane permeability depend on? a. Water, ions, and solubility b. Size, charge, and solubility c. Hypertonic, isotonic, and hypotonic d. Size, charge, and permeability 4.
