Phloem is inner.
Understanding the Position of Phloem
Based on the provided reference, let's explore the position of phloem in a tree:
- Reference B states: "The inner bark, or “phloem”, is pipeline through which food is passed to the rest of the tree." This clearly indicates that phloem is located within the inner bark of the tree.
Phloem's Role and Life Cycle
The reference also gives us insights into phloem's function and lifespan:
- Function: The phloem serves as a transport system for nutrients throughout the tree.
- Life Cycle: The phloem is not a permanent structure; it has a short lifespan. Once it dies, it turns into cork and becomes part of the outer protective layer of bark.
Phloem: Inner Bark
Here's a summary table showing the position of Phloem:
| Layer | Position | Composition |
|---|---|---|
| Inner Bark | Inner | Living Phloem (Food Transport) |
| Outer Bark | Outer | Dead Cork Cells (Protection) |
Conclusion
In conclusion, based on the information from our reference, phloem is located in the inner bark of a tree.
