Common between sclerenchyma and collenchyma is

Options

A. Material transport
B. Conduction of water and minerals
C. Providing buoyancy
D. Providing support

Answer

To solve the question "Common between sclerenchyma and collenchyma is," we will follow these steps:

### Step 1: Understand the Definitions
- **Sclerenchyma**: These are dead cells that provide mechanical support to the plant. Their cell walls are thickened with lignin, which makes them strong and rigid.
- **Collenchyma**: These are living cells that also provide mechanical support, but they have thicker cell walls than parenchyma cells, made up of cellulose, hemicellulose, and pectin. They are flexible and allow for some movement in young plants.

### Step 2: Identify the Functions
- Both sclerenchyma and collenchyma play a role in providing mechanical support to the plant.
- Sclerenchyma cells are typically found in mature tissues and provide rigid support, while collenchyma cells are found in young, growing parts of the plant and provide flexible support.

### Step 3: Analyze the Options
- **Option A: Material transport** - This is incorrect as neither sclerenchyma nor collenchyma are involved in the transport of materials; this is done by xylem and phloem.
- **Option B: Conduction of water and minerals** - This is also incorrect as this function is specific to xylem.
- **Option C: Providing buoyancy** - This is not applicable to either cell type as they do not primarily provide buoyancy.
- **Option D: Providing support** - This is correct as both sclerenchyma and collenchyma are involved in providing mechanical support to the plant.

### Step 4: Conclusion
The common function between sclerenchyma and collenchyma is that both types of cells provide mechanical support to the plant. Therefore, the correct answer is **Option D: Providing support**.
