Chapter 3

Front 1

Isotonic

Back 1

a solution that does not cause net osmotic flow of water in or out of a cell; equal movement of water

Front 2

hypotonic

Back 2

has more solutes and gains water through osmosis

Front 3

proteins

Back 3

integral and peripheral molecules that carry out special functions like transport of molecules and cell identification

Front 4

hypertonic

Back 4

low water concentration outside the cell; loses water through osmosis

Front 5

cholesterol

Back 5

lipid that keeps the membrane fluid

Front 6

cell division`

Back 6

process that allows cells to reproduce when needed for replacement or repair; known as mitosis

Front 7

phospholipid bilayer

Back 7

membrane contains 2 layers of molecules that are made up of a phosphate and a fatty acid; organized in a tail to tail manner because of water

Front 8

neoplasm

Back 8

abnormal cell division; uncontrolled reproduction of any cell; can be benign(non cancer) or malignant (cancer)

Front 9

functions of plasma membrane

Back 9

-physical barrier
-regulation of exchange with the environment
-sensitivity to the environment
-structural support

Front 10

membrane lipids

Back 10

double layer of phospholipid molecules
- hydrophilic heads-toward watery environment, both sides
-hydrophobic fatty acid tails-inside membranes
