In dicot stem, pericycle is present on the inner side of the endodermis and above the phloem in the form of semi lunar patches is made of :

Options

A. Parenchyma
B. Collenchyma
C. Sclerenchyma
D. All

Answer

To solve the question regarding the composition of the pericycle in a dicot stem, we can follow these steps:

### Step 1: Understand the Structure of a Dicot Stem
In a dicot stem, the vascular tissue is organized into bundles, which include xylem and phloem. The pericycle is a layer of cells that is located just inside the endodermis and above the phloem.

**Hint:** Remember the arrangement of tissues in a dicot stem, focusing on the vascular bundles.

### Step 2: Identify the Location of the Pericycle
The pericycle is found on the inner side of the endodermis and is positioned above the phloem. It plays a role in the plant's growth and development.

**Hint:** Visualize the layers of the stem and locate the endodermis and phloem to find where the pericycle is situated.

### Step 3: Determine the Composition of the Pericycle
The question asks what type of tissue makes up the pericycle in a dicot stem. The pericycle in dicot stems is primarily composed of sclerenchyma tissue, which is known for providing structural support.

**Hint:** Recall the types of ground tissues in plants and their characteristics, focusing on sclerenchyma.

### Step 4: Analyze the Options Given
The options provided are parenchyma, collenchyma, sclerenchyma, and all. Since we have established that the pericycle in dicot stems is made of sclerenchyma, we can eliminate the other options.

**Hint:** Compare the characteristics of parenchyma, collenchyma, and sclerenchyma to confirm which one fits the description of the pericycle.

### Step 5: Conclude the Answer
Based on the analysis, the correct answer is that the pericycle in a dicot stem is made up of sclerenchyma.

**Final Answer:** Sclerenchyma
