Term
| What does passive transport mean? |
|
Definition
| it doesn't require energy to take place |
|
|
Term
| By looking at the image, describe high concentration to low concentration as far as water molecules in diffusion. |
|
Definition
| When I look at the picture and hear that they go from high to low concentration I think that it means as they move along the molecules get less and less stronger. |
|
|
Term
| Water travels from ______ water concentration to a _______ water concentration |
|
Definition
|
|
Term
| Pick the correct statement |
|
Definition
| Solutes are dissolved into a solvent |
|
|
Term
| A low water concentration means a __________ solute concentration |
|
Definition
|
|
Term
| True or False: Water moves toward a high solute concentration |
|
Definition
|
|
Term
| A high solute concentration means there is _____ water concentration. |
|
Definition
|
|
Term
| Why do the water molecules move to side B? |
|
Definition
| They move to side B because that is the side with the high solute. |
|
|
Term
| Water will move to the side of the membrane where there is _____ concentration of solutes. |
|
Definition
|
|
Term
| So....what does "semipermeable" mean in reference to the cell membrane? |
|
Definition
| It lets tiny things pass through but not big |
|
|
Term
| What happens when salt is added to one side? |
|
Definition
| The water molecules move from low solute to high solute side. |
|
|
Term
| True or False: Water will stop moving through the cell membrane completely once the concentration of the water is the same on both sides. |
|
Definition
|
|
Term
| What does "hypertonic" mean in relation to concentration levels? |
|
Definition
| It has the high amount of solute. |
|
|
Term
| If you were to compare hypertonic to hypotonic, how does the concentration of each compare to the other? |
|
Definition
| The hyper tonic side has a high amount of solute, and the hypo-tonic side has a low amount. |
|
|
Term
| The side with more solutes is |

Term
| Why would the pure water go to the blood cells? |
|
Definition
| It would make them swell and burst. |
|
|
Term
|
Definition
|
|
Term
| How would you differentiate between HYPERtonic, ISOtonic and HYPOtonic solutions and their effect on blood cells? |
|
Definition
| If something is hyper-tonic it has a high solute concentration, if it is hypo-tonic then it has a low solute concentration, and isotonic is when everything is stable and equal. |
|
|
Term
| Why would the freshwater do to the saltwater? |
|
Definition
| It would make it swell and explode. |
|
|
Term
| So...why does the water in the soil go TO the plant roots exactly? Explain your answer |
|
Definition
| The soil is hypertonic so therefore the water will move in the dirt towards the roots and gives the plant nutrience |
|
|
Term
| Why do so many plants by roadsides die in the winter after roads have been salted? |
|
Definition
| The salt makes the soil hypertonic so the water doesn't travel to the root hairs |
|
|
Term
| So if the slug is HYPOtonic and the salt is HYPERtonic, where and why is the water moving? |
|
Definition
| The water is moving toward the salt and then the salt becomes the base of the slug which hen dries out the slug. |
