Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

15 notecards = 4 pages (4 cards per page)

Osmosis

front 1

The diffusion of a substance across a biological membrane is what?

back 1

Passive transport, because no energy is expended by the cell to make it happen

front 2

What is osmosis?

back 2

The diffusion of water across a selectively permeable membrane

front 3

Water diffuses across a from the region of?

back 3

Lower solute to higher solute, until it is equal on both sides.

front 4

What is the ability of a surrounding solution to cause a cell to gain or lose water?

back 4

Tonicity

front 5

* Solute concentration is the same as that inside the cell no net water movement across the plasma membrane *

back 5

Isotonic solution

front 6

Solute concentration is Greater than that inside the cell; cell loses water

back 6

Hypertonic solution (shriveling)

front 7

Solute concentration is Less then that inside of the cell; cell gains water.

back 7

Hypotonic solution (burst)

front 8

What creates problems for organisms?

back 8

hypotonic and hypertonic environments

front 9

The control of solute concentrations and water balance is a necessary adaption for life in such environments.

back 9

Osmoregulation

front 10

What has a contractile vacuole that acts as a pump?

back 10

The protest paramecium, which is hypertonic, to its pond water

front 11

Cell walls help maintain what?

back 11

water balance

front 12

A plant cell in a hypotonic solution swells until the wall opposes uptake; the cell is now what?

back 12

Turgid (firm)

front 13

If a plant cells surroundings are isotonic, then?

back 13

There is no net movement of qater into the cell; the cell becomes flaccid (limp) and the plant may wilt

front 14

In a hypertonic environment, plant cells lose water, eventually?

back 14

The membrane pulls away form the wall

front 15

This is a lethal effect called

back 15

Plasmolysis
