Soln & The Cell 2

hyper, hypo, isonic solutions & pH

QuestionAnswer
a gel-like liquid that fills the cell cytoplasm
a solution that is more concentrated than the cytoplasm of the cell hypertonic solution
a solution that is less concentrated than the cytoplasm of the cell hypotonic solution
a solution that has the same concentration as the cell isotonic solution
When a cell is placed in a hypertonic solution, in which direction does the water move? The water moves from dilute to concentrated areas; therefore, water moves out of the cell.
When a cell is placed in a hypotonic solution, in which direction does the water move? The water moves from dilute to concentrated areas; therefore the water will move into the cell.
When a cell is placed in an isotonic solution, in which direction will the water move? Because the concentration is the same inside and outside the cell, there is no net movement of water.
What would be the result of placing an animal cell in a hypotonic solution? The animal cell would swell and could burst and die.
What would be the result of placing a plant cell in a hypotonic solution? The plant cell would swell, but the cell wall would prevent it from bursting. This is a normal state for the plant cell.
What would be the result of placing a plant or animal cell in a hypertonic solution? Both cells would shrivel and could die.
What would be the result of placing a plant or animal cell in an isotonic solution? No change because both have the same concentration, and water would move back and forth at the same rate.
When a patient receives IV fluids at the hospital, what type of solution is used? isotonic solution
When using saline solution to rinse contact lenses or to hydrate the eyes, what type of solution is used? isotonic
If someone stranded in the ocean drinks the ocean water, what would happen to the cells in their body? The cells would shrivel and die because salt water is hypertonic to the cells of the body.
Why are bleach and ammonia good disinfectants for killing bacteria? They are solutions that are hypertonic to the bacteria, and cause them to shrivel and die.
Even though water is covalently bonded, what two ions can a very small amount of water molecules break into? H+ and OH-
Which ion from water makes a solution acidic? H+ ion
Which ion from water makes a solution basic? OH-
the measure of the acidity H+ of a solution is called pH
If the pH is less than 7, the solution is acidic
If the pH is greater than 7, the solution is basic
If the pH is equal to 7, the solution is neutral
What is the pH of the strongest acid? 0
What is the pH of the strongest base? 14
An organism's ability to maintain a stable internal environment homeostasis
Why must cells maintain a narrow pH range? To maintain homeostasis; if not the cell may be harmed or die.
How many times stronger is each step on the pH scale? 10x
Which is stronger an acid with a pH of 1 or an acid with a pH of 2? How much stronger? An acid with a pH of 1 is 10x stronger than an acid with a pH of 2.
Which is stronger, a base with a pH of 13 or a base with a pH of 14? How much stronger? A base with a pH of 13 is 10x stronger than a base with a pH of 14.
Which is stronger, an acid with a pH of 4 or an acid with a pH of 6? How much stronger? An acid with a pH of 4 is 100x (10x10) times stronger than an acid with a pH of 6.
Which is stronger, a base with a pH of 8 or a base with a pH of 11? How much stronger A base with a pH of 11 is 1000x (10v10x10) stronger than a base with a pH of 8.
What happens as a result of acid rain? Plant and aquatic life cannot maintain homeostasis and die.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
