Cell Membranes

Question 0

Isotonic

Answer 0

Equal substance in the inside and outside

Question 1

Hypotonic

Answer 1

More substance inside the cell, less on the outside

Think of hypotonic as hippo because hippos are bigger. And the cell gets bigger

Question 2

Solution

Answer 2

Mixture of substance dissolved in water

Question 3

Solvent

Answer 3

Water particles

Question 4

Hypertonic

Answer 4

More substance outside the cell and less on the inside

Question 5

Concentration

Answer 5

Discription of how much solute is dissolved in the water

Question 6

Passive transport

Answer 6

Movement of particles down the concentration gradient. No energy

Question 7

Diffusion

Answer 7

Process in which molecules move from high concentrate to low concentrate

Question 8

Osmosis

Answer 8

Diffusion of water through a semi permeable membrane

Question 9

Active transport

Answer 9

Movement of particles up the concentration gradient. Low concentration to high concentration. Requires energy

Question 10

Phospholipids

Answer 10

Made up of hydrophilic head and hydrophobia tails.
Heads from outside and inside since environment is usually wet

Hydrophilic=likes water
Hydrophobia=hates water

Question 11

Are cell membranes semi permeable

Answer 11

Yes!!

Question 12

Concentration gradient

Answer 12

How concentration changes from one to another

Question 13

Protein channel

Answer 13

This is embedded in the cell membrane and allows facilitated diffusion to occur

Question 14

Solute

Answer 14

Other particles
