Physical challenges key terms

Question 1

Venus fly trap, Sundew, Pitcher plant

Answer 1

Plants that adapted

Question 2

Solution, solvent, solute

Answer 2

Kool-aid, water, sugar (solution - mix of solute particles dissolved into solvent, solvent - substance into which material can be dissolved, solute - particles which dissolve into solvent)

Question 3

Diffusion

Answer 3

Movement of solute particles from region of high concentration to low concentration in order to establish an equilibrium (equal spacing between the molecules) - essential oil diffuser

Question 4

Dialysis

Answer 4

Movement of solute particles across a semi permeable membrane from a region of high concentration (of solute particles) to a region of low concentration

Question 5

Osmosis

Answer 5

Movement of solute particles (water) across a semi permeable membrane from an area of low concentration to area of high concentration

Question 6

Tonicity

Answer 6

Relative amount of solute in a solution

Question 7

Hypertonic

Answer 7

Solution has more solute particles per unit volume than a reference solution (IE - ocean fish example)

Question 8

Isotonic

Answer 8

Solution has the same solute particles

Question 9

Hypotonic

Answer 9

Solution has less solute particles (fresh water fish example)
