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
