Obturators which help in fertilization are out growth of

Options

A. Pollen tube
B. Stigma
C. Placenta or funiculus
D. Pollen grains

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about "obturators" that assist in fertilization and what they are an outgrowth of.

2. **Defining Obturators**: Obturators are structures that facilitate the movement of the pollen tube towards the ovule during fertilization. They play a crucial role in ensuring that the pollen tube reaches its destination.

3. **Analyzing the Options**: The options provided are:
- A) Pollen tube
- B) Pollen grain
- C) Placenta or Funiculus
- D) Stigma

4. **Evaluating Each Option**:
- **Option A (Pollen tube)**: This is incorrect because the obturator is not a part of the pollen tube; rather, it assists the pollen tube.
- **Option B (Pollen grain)**: This is also incorrect as the pollen grain is the male gamete and does not give rise to obturators.
- **Option C (Placenta or Funiculus)**: This is the correct answer. The placenta or funiculus is the structure that provides support and nourishment to the ovule and is involved in the growth of obturators that help guide the pollen tube.
- **Option D (Stigma)**: This is incorrect because the stigma is the part of the female reproductive system where the pollen lands, but it does not produce obturators.

5. **Conclusion**: After evaluating all the options, the correct answer is **C) Placenta or Funiculus**. This is because the obturators are outgrowths of the placenta or funiculus that assist in the fertilization process by guiding the pollen tube.
