Questions and Answers

What is the primary function of the root system in a plant?

  • To provide structural support for the plant's stems and leaves
  • To absorb and transport nutrients from the soil (correct)
  • To regulate the plant's water loss through transpiration
  • To store excess energy produced by photosynthesis

    • Which part of the root system is responsible for absorbing water and minerals from the soil?

  • Stem
  • Lateral roots
  • Root hairs (correct)
  • Taproot

    • What is the primary difference between a taproot and a lateral root?

  • Taproots are thicker, while lateral roots are thinner
  • Taproots are found in monocots, while lateral roots are found in dicots
  • Taproots grow faster, while lateral roots grow slower
  • Taproots grow deeper, while lateral roots grow wider (correct)
