Wood is separated from phloem in dicots by

Options

A. Pericycle
B. Cortex
C. Vascular cambium
D. Interfascicular cambium

Answer

To solve the question "Wood is separated from phloem in dicots by", we need to analyze the structure of dicot stems and identify the layers involved. Here’s a step-by-step breakdown:

### Step 1: Understand the Structure of Dicot Stems
In dicot plants, the stem contains various layers, including the outer bark, phloem, vascular cambium, xylem (wood), and pith. The xylem is responsible for water transport, while the phloem transports nutrients.

**Hint:** Remember that dicots have a specific arrangement of vascular tissues.

### Step 2: Identify the Vascular Cambium
The vascular cambium is a layer of meristematic tissue located between the xylem and phloem. It is responsible for the secondary growth in plants, allowing them to grow thicker.

**Hint:** Think of the vascular cambium as a growth layer that contributes to the increase in the diameter of the stem.

### Step 3: Distinguish Between Xylem and Phloem
In the context of the question, xylem (wood) is located towards the inside of the stem, while phloem is located towards the outside. The vascular cambium is the layer that separates these two tissues.

**Hint:** Visualize the arrangement: xylem is inner, phloem is outer, and the cambium is the dividing layer.

### Step 4: Conclude the Answer
Based on the understanding of the structure, we can conclude that the wood (xylem) is separated from the phloem by the vascular cambium.

**Hint:** Recall that the term "vascular" relates to the transport tissues in plants.

### Final Answer
Wood is separated from phloem in dicots by the **vascular cambium**.
