The type of placentation that occurs in sunflower is

Options

A. Marginal
B. Free central
C. Parietal
D. Basal

Answer

**Step-by-Step Solution:**

1. **Understanding Placentation:**
- Placentation refers to the arrangement of ovules within the ovary of a flower. It is crucial for the transfer of nutrients from the maternal plant to the developing embryo.

2. **Identifying Types of Placentation:**
- There are several types of placentation, including:
- Marginal
- Axile
- Parietal
- Basal
- Free central

3. **Analyzing the Sunflower:**
- The sunflower (Helianthus annuus) is known for its unique floral structure. To determine the type of placentation in sunflowers, we need to look at the arrangement of ovules in the ovary.

4. **Determining the Correct Type:**
- In sunflowers, the ovary has a basal type of placentation. This means that the placenta develops from the base of the ovary, and typically, a single ovule is attached at the base.

5. **Conclusion:**
- Therefore, the type of placentation that occurs in sunflowers is **basal placentation**.
