Classic Classic Quiz C3 - Movement of Substances by MdmAng MdmAng 1 573 played - 10 yrs ago Test yourself on the on concepts of diffusion and osmosis! QUIZ 10 QUESTIONS hard 1 The cell has reached _____________ when the concentration of a solute inside and outside a cell is the same. Dynamic equilibriumEqual water potentialMaximum concentrationNet osmotic pressure 2 The diffusion of oxygen into red blood cells does not require the ________________. Random motion of oxygen moleculesConcentration gradient of oxygen moleculesPartially permeable membrane of red blood cellsCollision between oxygen molecules and red blood cells 3 Which factors does NOT affect diffusion? Concentration gradientSurface area to volume ratioTemperatureThickness of plant cell wall 4 Gases like oxygen and carbon dioxide move across cell surface membranes through _____________________. Chemical reactionDiffusionFiltrationOsmosis 5 Which processes does NOT involve diffusion? Digested food molecules are absorbed into the blood.Metabolic wastes move out of the cells into the blood.Red blood cells shrinking when placed in a concentrated sugar solution.Oxygen moves into and carbon dioxide move out of the cell during respiration. 6 Root hair cell sap contains ions and dissolved nutrients in its vacuoles. What can we say about the cell sap? Cell sap has a lower water potential than that of the soil solution.Cell sap has a higher water potential than that of the soil solution.Cell sap has a lower water concentration than that of the soil solution.Cell sap has a higher water concentration than that of the soil solution. 7 What can happen if we put too much fertilizer into the soil? The plant will absorb too much water through its roots.The plant will lose too much water through its roots.The plant will absorb more fertilizer and grow better.The plant will aborb the same amount of fertilizer and water. 8 Arrange the following from highest to lowest water potential. Corn syrup > cell sap > mineral water > distilled waterCell sap > corn syrup > mineral water > distilled waterDistilled water > mineral water > corn syrup > cell sapDistilled water > mineral water > cell sap > corn syrup 9 A Visking tubing of water is placed in a beaker of sugar solution as shown. What can be observed in the glass tube after 20 minutes? The liquid level in the glass tube falls and stops.The liquid level in the glass tube falls continuously.The liquid level in the glass tube rises continuously.The liquid level in the glass tube remains the same. 10 Referring to the above experiment, what will happen if water is added into the sugar solution in the beaker? The liquid level continues to fall but more slowly now.The liquid level continues to fall but more quickly now.The liquid level continues to rise but more slowly now.The liquid level continues to rise but more quickly now A mistake in this Quiz ?
