1. Chapter 2 – Plant Structures and Functions Plant Transport Systems
Lesson 2 –
Plant Transport Systems

2. How do different materials move in plants?
Roots
xylem: moves water and minerals up from roots to the stem
phloem: carries sugar from leaves down the stem and into roots

3. How do different materials move in plants?
Roots
taproots: thick; grow deep (carrots, beets)
fibrous roots: thin (grass)
prop roots: finger-like (corn)

4. What is the transport system made of?
Xylem and phloem continue up from the roots all the way through the stem.
cambium: layer in stem where new xylem and phloem are made.

5. Tree Rings
Bark (protective outer layer)
phloem
xylem

6. Tree Rings
A ring of xylem grows every year, so you can count the rings to determine the age of the tree.
