Question 1

Question
what are the types of passive transport?
Answer
  • Diffusion
  • facilitated diffusion
  • active transport
  • osmosis

Question 2

Question
what movement of particles is diffusion?
Answer
  • movement from an area of high concentration to an area of low concentration
  • movement from an area of low concentration to an area of high concentration

Question 3

Question
Passive transport means energy is required
Answer
  • True
  • False

Question 4

Question
Whats the difference between diffusion and facilitated diffusion?
Answer
  • theres no difference
  • facilitated diffusion uses carrier proteins
  • facilitated diffusion requires energy
  • diffusion is through a semi-permeable membrane and facilitated diffusion is through a permeable membrane

Question 5

Question
Active transport is the movement of particles from an area of low concentration to an area of high concentration
Answer
  • True
  • False

Question 6

Question
what factors affect diffusion
Answer
  • concentration gradient, (difference between the two regions)
  • distance
  • barriers
  • surface area
  • energy demand

Question 7

Question
what is osmosis?
Answer
  • a passive movement of water through a semi-permeable membrane
  • a process of diffusion where energy is required to move water through a semi-permeable membrane

Question 8

Question
passive transport is when the particles are moved down the concentration gradient
Answer
  • True
  • False
