Diffusion, Osmosis , Active Transport

• diffusion

  net movement of particles across an high concentration to an area of low concentration
• osmosis

  net movement of water particles across an area of high concentration to an area of low concentration through a partially permeable membrane
• active transport

  net movement of particles from an area of low concentration to an area of high concentration
• faster rate of diffusion is having a

  • bigger concentration gradient
  • high temperature
• diffusion occurs in liquids or gases
• root hair cells in plants uses active transport
• active transport stops starving
• kidney tubules use active transport
