Meiosis not occurs in :-

Options

A. Ovule
B. Anther
C. Microporangia
D. Shoot tip

Answer

To determine where meiosis does not occur, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells. It is essential for sexual reproduction and occurs in specific structures in plants and animals.

2. **Evaluate Each Option**:
- **Option 1: Ovule**: Meiosis occurs in the ovule, which is the structure that develops into seeds after fertilization. It undergoes meiosis to form megaspores.
- **Option 2: Anther**: The anther is part of the stamen in flowering plants and contains pollen sacs. Meiosis occurs here to produce microspores, which develop into pollen grains.
- **Option 3: Microsporangia**: Microsporangia are structures that produce microspores through meiosis. Therefore, meiosis occurs here as well.
- **Option 4: Shoot Tip**: The shoot tip is involved in the growth of the plant and does not undergo meiosis. It primarily involves mitotic divisions for growth and development.

3. **Identify the Correct Answer**: Based on the analysis above, the correct answer is **Option 4: Shoot Tip**, as meiosis does not occur in this structure.

### Final Answer:
Meiosis does not occur in the **shoot tip**.
