Questions and Answers

What is the primary function of the internode in a typical stem?

  • To provide a space for the growth of new nodes (correct)
  • To support the weight of the leaves and flowers
  • To facilitate the absorption of sunlight by the leaves
  • To transport water and nutrients from the root to the leaves

    • What is the main difference between a vegetative bud and a reproductive bud?

  • Vegetative buds are larger than reproductive buds
  • Vegetative buds are found on the roots, while reproductive buds are found on the stems
  • Vegetative buds develop into leaves, while reproductive buds develop into flowers (correct)
  • Vegetative buds are responsible for transporting water, while reproductive buds are responsible for transporting food

    • What is the role of the xylem in the plant?

  • To transport food made in the leaves to other parts of the plant
  • To carry water from the roots through the stem and through the veins in the leaves (correct)
  • To facilitate the absorption of sunlight by the leaves
  • To support the weight of the leaves and flowers

    Study Notes

    The Shoot System

    • Develops from the plumule after embryo in the seed
    • Grows above ground and consists of a stem bearing branches, leaves, flowers, and fruits

    Types of Buds

    • Vegetative buds: develop into leaves, branches, or other vegetative parts of the plant
    • Reproductive or flower buds: develop into flowers or groups of flowers

    Typical Stem Structure

    • Has leaves at regular intervals (nodes) with buds at the axle of the leaf
    • Has a terminal bud at the growing point
    • Internodes are the lengths of stem between nodes
    • Typically stands erect from the ground

    Functions of Stems

    • Connects the root system to the leaves and flowers of the shoot system
    • Supports all parts of the shoot system, including branches, leaves, buds, flowers, and fruits
    • Facilitates absorption of maximum sunlight through leaf arrangement
    • Transports water and dissolved minerals and nutrients from roots to leaves
    • Transports food (e.g., sugars) made in leaves to other parts of the plant where needed or stored

    Transport in the Stem

    • Network of tubes (xylem and phloem) transport water, food, and other substances throughout the plant
    • Xylem: consists of xylem vessels, responsible for carrying water from roots through stem and veins in leaves
    • Phloem: made of sieve tubes, responsible for carrying food made in leaves to other parts of the plant
