Ram wanted to see the internal structure of a plant stem. He took the transfer section of the stem and observed under the microscope. He saw a number of cells arranged in 3-4 layers of parenchyma cells, followed by pericycle. To which tissue system do these parts belong to?

A

Vascular tissue system

B

Ground tissue system

C

Epidermal tissue system

D

Meristematic tissue

The correct Answer is:
To determine the tissue system to which the observed parts of the plant stem belong, we can follow these steps: ### Step 1: Identify the Observed Structures Ram observed: - **Parenchyma cells**: These are living cells that are typically found in various parts of the plant and are involved in storage, photosynthesis, and tissue repair. - **Pericycle**: This is a layer of cells located just inside the endodermis in roots and stems, involved in the formation of lateral roots and can also contribute to secondary growth. ### Step 2: Understand the Tissue Systems Plant tissues are classified into three main systems: 1. **Dermal Tissue System**: This is the outer protective layer of the plant. 2. **Vascular Tissue System**: This includes xylem and phloem, responsible for the transport of water, nutrients, and food. 3. **Ground Tissue System**: This includes all tissues that are neither dermal nor vascular. It mainly consists of parenchyma, collenchyma, and sclerenchyma. ### Step 3: Classify the Observed Structures - The **parenchyma cells** are part of the ground tissue system, as they are involved in storage and metabolic functions. - The **pericycle** is also part of the ground tissue system, as it is a layer of cells that contributes to the growth and development of the plant. ### Conclusion Both the parenchyma cells and the pericycle belong to the **Ground Tissue System** of the plant. ### Final Answer The parts observed by Ram (parenchyma cells and pericycle) belong to the **Ground Tissue System**. ---
