The grit of guava is made up of

Options

A. collenchyma tissue
B. parenchyma tissue
C. aerenchyma tissue
D. sclerenchyma tissue

Explanation

**Step-by-Step Solution:**

1. **Understand the Structure of Guava Grit:** The grit of guava refers to the hard, gritty texture found in the fruit, which is primarily located in the outer surface of the guava.

2. **Identify the Types of Tissues:** In plants, there are different types of tissues that serve various functions. The main types of tissues relevant to this question are:
- Parenchyma: Living cells involved in storage and photosynthesis.
- Collenchyma: Living cells that provide support and flexibility.
- Sclerenchyma: Dead cells that provide rigidity and strength.

3. **Focus on the Function of Sclerenchyma:** The outer surface of the guava is made up of dead cells that are stiff and hard. This is characteristic of sclerenchyma tissue, which is known for its protective role and structural support due to the presence of lignin in its cell walls.

4. **Conclude the Composition of Guava Grit:** Since the grit of guava is primarily made up of hard, dead cells that provide protection and rigidity, we can conclude that it is made up of sclerenchyma tissue.

5. **Final Answer:** The grit of guava is made up of sclerenchyma tissue.
