Summary
The plant transport system consists of two main parts: the xylem and the phloem. These structures are essential for transporting water, minerals, and food throughout the plant.
- Xylem — a tube that transports water and mineral salts from the roots to all parts of the plant. Example: The xylem helps deliver water to the leaves for photosynthesis.
- Phloem — a tube that transports food made in the leaves to all parts of the plant. Example: The phloem distributes sugars produced in the leaves to the roots and stems.
Exam Tips
Key Definitions to Remember
- Xylem: A tube that transports water and mineral salts from the roots to all parts of the plant.
- Phloem: A tube that transports food made in the leaves to all parts of the plant.
Common Confusions
- Confusing the direction of transport in xylem and phloem.
- Thinking that xylem and phloem transport the same substances.
Typical Exam Questions
- What does the xylem transport? Water and mineral salts.
- What does the phloem transport? Food made in the leaves.
- How do xylem and phloem differ in their function? Xylem transports water and minerals; phloem transports food.
What Examiners Usually Test
- The function of xylem and phloem in the plant transport system.
- The direction of transport in xylem and phloem.
