ground tissue having differentiated concentric layers is found in

Options

A. dicot leaf
B. monocot leaf
C. dicot stem
D. monocot stem

Answer

To solve the question regarding which plant structure has ground tissue with differentiated concentric layers, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a plant structure that has ground tissue with differentiated concentric layers. Ground tissue is a type of tissue found in plants that is responsible for storage, support, and photosynthesis.

2. **Identify the Types of Plant Structures**: We need to consider the different types of plant structures mentioned in the question, such as dicot leaves, monocot leaves, dicot stems, and monocot stems.

3. **Analyze Dicot Leaves**: In dicot leaves, the ground tissue is known as mesophyll, which is differentiated into palisade and spongy parenchyma. However, this differentiation does not form concentric layers.

4. **Analyze Monocot Leaves**: In monocot leaves, the ground tissue is also mesophyll, but it is not differentiated into distinct layers. It primarily consists of spongy parenchyma.

5. **Analyze Dicot Stems**: In dicot stems, the ground tissue is referred to as the cortex. The cortex is differentiated into several concentric layers, including the hypodermis, general cortex, and endodermis. This structure fits the description of having differentiated concentric layers.

6. **Analyze Monocot Stems**: In monocot stems, the ground tissue has a scattered arrangement of vascular bundles and does not have differentiated concentric layers.

7. **Conclusion**: Based on the analysis, the only structure that has ground tissue with differentiated concentric layers is the dicot stem.

### Final Answer:
The ground tissue having differentiated concentric layers is found in the **dicot stem**.
