Oldest phloem occurs on the outerside of phloem/inner to pericycle. It is actually

Options

A. primary phloem
B. secondary phloem
C. included phloem
D. crushed secondary phloem

Answer

To answer the question regarding the location of the oldest phloem in relation to the pericycle and other plant structures, we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding Plant Structure**:
- In flowering plants, the vascular tissue consists of xylem and phloem, which are responsible for the transport of water, nutrients, and food.

2. **Identifying the Cambium**:
- The cambium is a layer of meristematic tissue that is responsible for secondary growth in plants. It is located between the xylem and phloem.

3. **Differentiating Between Primary and Secondary Phloem**:
- Primary phloem is formed during the initial stages of growth, while secondary phloem is produced by the cambium during secondary growth.

4. **Locating the Oldest Phloem**:
- The oldest phloem is found on the outer side of the phloem tissue. It is located just inside the pericycle, which is a layer of cells that surrounds the vascular tissue.

5. **Conclusion**:
- Therefore, the statement that the oldest phloem occurs on the outer side of the phloem and inner to the pericycle is correct. The oldest phloem is indeed the primary phloem.

### Final Answer:
The oldest phloem occurs on the outer side of the phloem and is inner to the pericycle, which is primarily the primary phloem.
