  • It is a structural axis that supports the flowers, fruits, and leaves of a plant.
    Stem
  • What are the main functions of plant stems?
    1. Support
    2. Transport
    3. Food Storage
    4. Food Manufacturer
  • It connects the other organs of the plant.
    Stem
  • What are the two basic kinds of stem?
    1. Herbaceous Stem
    2. Woody Stem
  • This kind of stem is soft, green, and flexible.
    Herbaceous
  • This kind of stem contain thick, tough tissue (wood).
    Woody
  • The cell wall of herbaceous stems are made of...
    Cellulose
  • The cell wall of woody stems are made of...
    Cellulose and Lignin
  • It is a modified horizontal stems aboveground.
    Stolons
  • It is a modified underground stems that grow horizontally.
    Rhizomes
  • It is a modified usually swollen, underground stems that store nutrients and starch.
    Tubers
  • It is a modified stem. They are large buds surrounded by numerous fleshy leaves. It has fibrous roots at the base and contains basal plate and tunic.
    Bulbs
  • It is a short, solid, swollen stem whose scales have been reduced to a dry, leaf-life covering. It lacks visible storage leaves.
    Corms
  • Crocus and Gladiolus are examples of...
    Corms
  • The stem of ginger and fern is...
    Rhizomes
  • The stem of a strawberry plant is...
    Stolon
  • It is also called "runners" because in many plants, they run along the surface of the soil.
    Stolons
  • It is a point on the stem from which leaves or buds arise.
    Node
  • It is the portion between two successive nodes.
    Internode
  • It is an undeveloped or embryonic shoot that may develop into a flower or leaf. It normally occurs in the axil of a leaf or at the tip of a stem.
    Buds
  • What are the two types of buds?
    1. Terminal
    2. Axillary (lateral)
  • This type of bud is located at the tip of a stem.
    Terminal Buds
  • This type of bud is located at the axil (where leaves develop) of a leaf.
    Axillary Buds
  • Axillary Buds are also called...
    Lateral Buds
  • This is where leaves develop.
    Axil
  • The vascular bundle of monocot stems are...
    Scattered
  • The vascular bundle of dicot stems are...
    Ringed
  • The ground tissue of these stems are usually not clearly separated into Pith and Cortex.
    Monocot Stems
  • Most monocots have no secondary growth.
    True
  • Inside this stem, vascular bundles form a ring that divides the ground tissue into Cortex and Pith.
    Dicot Stem
  • It arises between the xylem and phloem, and it forms a cylinder and produces secondary xylem to the inside and secondary phloem to the outside. This secondary growth makes the stem wider and thicker.
    Vascular Cambium
  • It is a dark wood located at the center of the tree trunk, and serves as the supporting pillar of the tree.
    Heartwood
  • It is often lighter colored wood located nearer the outside of the tree trunk; it is the only part where the active xylem substance is located; it transmits water and other substances along the plant body; and it gives the tree hardness
    Sapwood
  • When the sapwood dies, it becomes the heartwood.
    True
  • This is a characteristic of gymnosperms and many eudicots, but not monocots.
    Secondary Growth
  • It is the phloem produced near the outside of the stem, and is the protective covering of woody plants.
    Bark
  • It is a ring formed each year, and is a way to estimate the age of the stem (tree).
    Annual Rings
  • Flowering plants can be categorized based on the length of their life cycle:
    1. Annuals
    2. Biennials
    3. Perennials
  • This refers to plants that complete their life cycle in a year or less.
    Annuals
  • This refers to plants that require two growing seasons.
    Biennials
