Which of the following tissue provides mechanical support to the growing parts of the plant such as young stem and petiole of a leaf

Options

A. Parenchyma
B. Collenchyma
C. Sclerieds
D. Fibres

Answer

To solve the question regarding which tissue provides mechanical support to the growing parts of the plant, such as the young stem and petiole of a leaf, we can follow these steps:

### Step 1: Identify the Types of Tissues
First, we need to understand the types of tissues mentioned in the options:
- **Parenchyma**: This is a type of ground tissue that is involved in various functions such as storage, photosynthesis, and secretion.
- **Collenchyma**: This tissue provides support, particularly in young and growing parts of the plant.
- **Sclerenchyma**: This tissue provides support to mature parts of the plant and is composed of fibers and sclereids.
- **Fibers**: These are a type of sclerenchyma tissue that also provides support.

### Step 2: Analyze the Function of Each Tissue
Next, we analyze the function of each tissue in relation to the question:
- **Parenchyma** does not primarily provide mechanical support; it is more involved in metabolic functions.
- **Collenchyma** is specifically designed to provide mechanical support to growing parts of the plant, such as young stems and petioles.
- **Sclerenchyma**, while providing support, is more suited for mature tissues rather than growing parts.
- **Fibers** are part of sclerenchyma and also do not support growing tissues.

### Step 3: Conclusion
Based on the analysis, the tissue that provides mechanical support to the growing parts of the plant, such as the young stem and petiole of a leaf, is **Collenchyma**.

### Final Answer
The correct option for this question is **Collenchyma**.
