Questions and Answers

What is the main difference between bulbs and corms?

  • Corms are composed of stem tissue, while bulbs lack fleshy leaf scales
  • Bulbs and corms are the same type of underground storage structure
  • Bulbs and corms are both composed of root tissue
  • Bulbs are composed of stem tissue, while corms lack fleshy leaf scales (correct)
  • What is the main function of the taproot system in plants?

  • Storing reserve food for the plant
  • Anchoring the plant and absorbing water and minerals (correct)
  • Allowing the plant to reproduce through seeds
  • Producing lateral roots for vegetative propagation
  • How do adventitious roots differ from the taproot system?

  • Adventitious roots are responsible for anchoring the plant, while taproot systems are responsible for absorption
  • Adventitious roots are found in monocot plants, while taproot systems are found in dicot plants (correct)
  • Adventitious roots develop from the radicle, while taproot systems develop from other parts of the plant
  • Adventitious roots are used for vegetative propagation, while taproot systems are used for seed germination

    Study Notes

    Stem Vasculature

    • Xylem carries water and minerals up the plant, while phloem carries food down
    • Vascular cambium produces new tissue for growth and creates rings in tree trunks
    • Different vascular arrangements in monocots and dicots affect herbicidal action

    Importance to Gardeners

    • Vascular cambium is crucial for grafting and must be protected during gardening activities
    • Careless weed trimming can harm the cambium, leading to plant death
    • Understanding stem vasculature is essential for plant health and productivity

    Stem Types

    • Tuberous stems are short, flat, and enlarged, with buds and shoots arising from the top and fibrous roots from the bottom
    • Corms lack fleshy leaf scales, distinguishing them from bulbs

    Roots

    • Roots are the underground part of the plant body, responsible for anchoring, absorbing water and minerals, and storing reserve foods
    • Types of roots include taproot or primary root system and adventitious root system
    • Taproot system is present in dicots, while adventitious roots are found in monocots

    Nodes and Internodes

    • Nodes are areas on stems where buds are located, allowing for growth and development
    • Pruning near nodes can stimulate bud development and encourage plant growth
    • Internodes are areas between nodes, affecting plant growth and structure
    • Internodal length is an indicator of a plant's health and productivity, affected by factors like soil fertility, light density, and seasons
