Study Notes
Stem Anatomy and Functions
- The outer covering of a herbaceous monocot stem is the cortex, providing protection and support.
- Lenticels are small openings in the bark that facilitate gas exchange by allowing air to enter the stem.
- A terminal bud is the large bud at the end of a twig responsible for the stem's elongation.
- The section of a twig between nodes is referred to as the internode, contributing to the overall length of the stem.
- Vascular bundles consist of xylem and phloem tubes in a herbaceous stem, crucial for nutrient and water transport.
Wood Structure and Types
- Xylem tissue, commonly known as wood, is essential for water and nutrient transport from roots to other parts of the plant.
- Heartwood is the older, inner wood of a stem that no longer conducts sap but provides structural support.
- The bark is the protective outer layer of a woody stem that contains vital phloem tissue for nutrient transfer.
Growth Patterns
- Trees exhibiting spirit-like branching grow tall and straight, characterized by minimal branching from a central shaft.
- An annual ring is formed by one layer of springwood and summerwood, indicating the plant's growth during different seasons.
