terms for bio topic 2

Question 1

Diffusion

Answer 1

~Particles moving for a high concentration to a low concentration.

~ Moving down the concentration gradient

~ Does not require any energy

Question 2

Osmosis

Answer 2

~ Diffusion of water from dilute solution to a more concentrated

~ Partially Permeable membrane

~ Does not require energy

Question 3

Active transport

Answer 3

~ Going from a low concentration to a high concentration

~ going up the concentration gradient

~ Does require energy to move molecules and ions across membranes against the concentration gradient
