Question 1

Fluid Mosaic

Answer 1

Structure of the membrane made of many flowing pieces

Question 2

Phospholipids

Answer 2

Main part of membrane comprised of a phosphate with two lipid tales

Question 3

Cholesterol

Answer 3

Between phospholipids stabilize membrane

Question 4

Protein

Answer 4

Part of structure places too attached to some all the way through for material transport

Question 5

Selective permeability

Answer 5

Membrane structure only allow certain materials through important for maintaining homeostasis

Question 6

Solution

Answer 6

Mixture of two substances with one dissolved in another

Question 7

Solvent

Answer 7

Larger part of solution, dissolves other substance, in biology this is typically water

Question 8

Brownian movement

Answer 8

Dissolved particles are in constant motion

Question 9

Passive transport

Answer 9

Movement of materials without using the cells energy

Question 10

Diffusion

Answer 10

Materials spread from high concentration to low concentration because of Brownian movement small molecules can diffuse between the phospholipids

Question 11

Dynamic equilibrium

Answer 11

And point of diffusion when particles are evenly distributed, but still moving

Question 12

Facilitated diffusion

Answer 12

Membrane proteins help large or charged molecules diffuse in or out by providing a place to pass

Question 13

Osmosis

Answer 13

Diffusion of water across the plasma membrane

Question 14

Isotonic

Answer 14

Equal concentrations of solutes

Question 15

Hypertonic

Answer 15

A higher concentration of solutes

Question 16

Active transport

Answer 16

Materials moved with cell energy, materials off and move from low to high concentration

Question 17

Membrane associated pumps

Answer 17

Proteins in the membrane push materials through the membrane

Question 18

Endocytosis

Answer 18

Bringing large amounts of material into a cell by wrapping the membrane around them

Question 19

Phagocytosis

Answer 19

Membrane extends out word to grab large solid particles

Question 20

Pseudopods

Answer 20

Extensions of the cell used for phagocytosis

Question 21

Pinocytosis

Answer 21

Membrane folds in word to collect liquids or lots of dissolved materials

Question 22

Exocytosis

Answer 22

Large amounts of materials removed from the cell when contractile vacuole attaches to membrane
