Question

Which of the following tissues is made up of more than one type of cell?

• A. Parenchyma
• B. Collenchyma
• C. Sclerenchyma
• D. Complex tissue

Answer 1

The correct option is D

Complex tissue

The correct option is D.

The explanation for the correct option:

1. Complex tissue is made up of multiple types of cells.
2. These are grouped together to perform similar functions, e.g. Xylem and Phloem.
3. Xylem transports water and minerals from roots to leaves.
4. Phloem distributes the food from leads to various parts of the plant.
5. These are also called vascular tissues.
6. These are consists of both dead and living tissues.

The explanation for the incorrect options:

Option A:

1. Parenchyma is a simple permanent tissue.
2. It is a polygonal living cell with a large central vacuole and intercellular spaces.
3. Parenchyma tissue is a spongy tissue.
4. It is also known as mesenchymal tissue.
5. They keep food and provide temporary assistance to the plant.

Option B:

1. Collenchyma is made up of living cells.
2. They are elongated and have small intercellular spaces.
3. Cellulose and pectin make up their cell walls.
4. It is found beneath the epidermis in the leaf stalks.
5. It provides mechanical support and flexibility to plants.

Option C:

1. Sclerenchyma is supportive tissue.
2. It is made up of various hard woody cells.
3. Once matured, sclerenchyma cells are usually dead cells.
4. These cells are found in bark and mature stems.

Final answer: Complex tissue is made up of more than one type of cell.
