The question is incomplete and the complete question is

Which is false about the Tilia stem?

Answer:

C) The xylem is located outside the phloem

Explanation:

Tilia americana is a tree which grows in the climate of Eastern America. The tree is dicotyledonous and therefore posses secondary growth.

The anatomy of the stem of the Tilia plant shows that the:

1. Pith - the pith is the central portion of the stem which is composed of the parenchymatous cells. The pith also contains the mucilage ducts.

2. Cortex - the cortex is the portion present inside the epidermal layer which is made of both the chloroplast containing cells called collenchyma cells and the parenchyma.

3. Epidermis - The outermost layer which is composed of the single layer of cells.

4. Vascular bundle - Since the phloem is located inside the xylem and not xylem is inside the phloem therefore in the given is the false statement.

Thus, Option-C is correct.
