Root Hair Cells

Root Hair Cells

Root Hair Cells

• Root hairs cells are found on the outer surface of plant roots; they have root hairs, which are extensions of the cell membrane that grow between soil particles and absorb water and minerals from the soil

  • The root hair increases the surface area of the cells significantly

  • This large surface area is important as it increases the rate of absorption

• Water enters the root hair cells by osmosis

  • This happens because soil water has a higher water potential than the cytoplasm of the root hair cell

• Minerals enter root hair cells by active transport
