Question

Ram wanted to see the internal structure of a plant stem. He took the transverse 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?

• A. Vascular tissue system
• B. Ground tissue system
• C. Epidermal tissue system
• D. Meristematic tissue

Answer 1

The correct option is B Ground tissue system

1. Vascular tissue system includes xylem and phloem and helps in food and water conduction.
2. Ground tissue system mainly consists of simple tissues such as parenchyma, collenchyma, and sclerenchyma. Parenchyma is usually present in cortex, pericycle, pith and medullary ray.
3. Epidermal tissue system forms the outer -most covering of the complete plant body. Stomata are present here.
4. Meristematic tissue contributes to the primary growth of the plant and includes apical and intercalary meristems.

So the correct option is "Ground tissue system".
