Roots of Plant Biology

Roots in Vascular Plants

• The primary function of roots in vascular plants is to anchor the plant, absorb water and minerals from the soil, and store food.

Root Morphology

• The four zones of root morphology are:
  • Zone of cell division, where the apical meristem produces new cells
  • Zone of elongation, where cells increase in length
  • Zone of maturation, where cells differentiate into specific types
  • Zone of root hairs, where root hairs are produced

Apical Meristem in Roots

• The apical meristem is responsible for producing new cells in the root, enabling it to grow and elongate.

Root Cap

• The root cap protects the apical meristem from mechanical injury and helps guide the root through the soil.

Root Hairs

• Root hairs primarily increase the surface area of the root, allowing it to absorb more water and minerals from the soil.
