Question

The tissue that commonly forms ground tissue is

• A. Epidermis
• B. Parenchyma
• C. Collenchyma
• D. Sclerenchyma

Answer 1

The correct option is B

Parenchyma

The correct option is B:

Explanation of the correct option:

1. The ground tissues arise from the ground meristem.
2. They are responsible for storing carbohydrates produced by plants and providing support.
3. They are located between dermal and vascular tissue.
4. The ground tissue comprises Parenchyma, Collenchyma, and Sclerenchyma cells.
5. Parenchyma cells make up the majority of ground tissue.
6. Parenchyma tissue is made up of mature cells that have lost the capacity for repeated division.
7. But on stimulation, they can attain the capability of revision.
8. Cells of Parenchyma are living, thin-walled, soft, and have a cellulosic cell wall.
9. The main function of Parenchyma cells is in photosynthesis and storage of food materials.

Explanation of incorrect options:

Option A:

1. The epidermis is the dermal tissue system.
2. They provide a protective barrier against mechanical injury, infection, and water loss.

Option C:

1. Cells of Collenchyma tissue are living cells.
2. The cell walls are thickened at the corners and are made up of cellulose, hemicellulose, and pectin.
3. The tissue is elastic, extensible, and can expand.
4. Hence, they provide support to the plant.

Option D:

1. Cells of Sclerenchyma tissue lack protoplasm.
2. Due to the deposition of lignin, they become dead, thick-walled, and hard.
3. They provide mechanical support to the plant.

Final Answer: Thus, The tissue that commonly forms ground tissue is Parenchyma.
