Vernalisation is commonly seen in plants like _____,which are _______ in nature.

Options

A. sugarbeet, annual
B. cabbage, perrenial
C. mustard, biennial
D. carrot, biennial

Answer

**Step-by-Step Solution:**

1. **Understanding Vernalization**: Vernalization is the process by which certain plants require a period of cold temperature to induce flowering. This adaptation helps plants time their flowering to coincide with favorable environmental conditions.

2. **Identifying Plant Types**: Plants can be classified into three categories based on their life cycles: annuals (complete life cycle in one year), biennials (complete life cycle in two years), and perennials (live for more than two years).

3. **Recognizing the Role of Temperature**: Some plants, particularly biennial plants, require exposure to low temperatures for a specific duration before they can flower. This is crucial for their development and is a natural phenomenon.

4. **Examples of Biennial Plants**: Common biennial plants that exhibit vernalization include carrots, sugar beets, and cabbages. These plants typically flower in their second year of growth after experiencing a cold period.

5. **Conclusion**: Based on the understanding of vernalization and the characteristics of biennial plants, the correct answer to the question is that vernalization is commonly seen in plants like **carrots**, which are **biennial** in nature.

**Final Answer**: Vernalisation is commonly seen in plants like **carrots**, which are **biennial** in nature.
