Root hair cell structure and their function

• Root hair plant functions

  • Absorb ater by osmosis
  • Take up mineral by active transport
  • Provide stability to the plant
• Root hair adaption

  • Large surface area t increase the rate of absorption
  • Long hair extensions that reach into the soil
  • no chloroplast so cant photosynthesis
• Explain how water is absorbed in the plant?

  Water moves by osmosis from an area of high concentration of water molecules to low concentration of water molecule down the concentration gradient. This occurs across a partially permeable membrane
• Mineral Tranpsort

  • The concentration of mineral in soil water is low compared to the minerals in a plant. This mean the minerals in the soil water has to be taken by the root , they must be absorbed against the concentration gradient. This is the movement of particles from an of low concentration to a an area of high concentration.Active transport requires energy
