In plants, meiosis can be observed in :-

Options

A. Root tip
B. Leaf primordia
C. Sporangia
D. Spores

Answer

To solve the question "In plants, meiosis can be observed in:", we need to analyze each of the provided options to determine where meiosis occurs.

### Step-by-Step Solution:

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

2. **Analyzing the Options**:
- **Option 1: Root Tip**
- In root tips, cell division primarily occurs through mitosis, not meiosis. Mitosis is responsible for growth and development in the root.
- **Conclusion**: This option is incorrect.

- **Option 2: Leaf Primordia**
- Similar to root tips, leaf primordia also undergo mitosis for the growth and development of leaves. Meiosis does not occur here.
- **Conclusion**: This option is incorrect.

- **Option 3: Sporangia**
- Sporangia are structures in which spores are produced. In plants, meiosis occurs in sporangia to produce haploid spores, which are essential for reproduction.
- **Conclusion**: This option is correct.

- **Option 4: Spores**
- Spores are the result of meiosis that occurs in sporangia. They are not the structures where meiosis takes place.
- **Conclusion**: This option is incorrect.

3. **Final Answer**: Based on the analysis, the correct answer is **Option 3: Sporangia**, as meiosis occurs in sporangia leading to the formation of haploid spores.
