Haploid plantlets can be produced by

Options

A. pollen culture
B. cotyledon culture
C. embryo culture
D. meristem culture

Answer

To answer the question "Haploid plantlets can be produced by," we will analyze the options provided and determine which one is correct based on the understanding of haploid plantlets and their production methods.

### Step-by-Step Solution:

1. **Understanding Haploid Plantlets**:
- Haploid plantlets are plants that have only one set of chromosomes (n). They are typically produced from gametes (sperm and egg cells) without fertilization.

2. **Analyzing the Options**:
- **Pollen Culture**: This method involves culturing pollen grains in a nutrient medium. Pollen grains are haploid, and when cultured properly, they can develop into haploid plantlets.
- **Cotyledon Culture**: This method involves using the cotyledons (seed leaves) of a plant. Cotyledons are diploid and do not produce haploid plantlets.
- **Embryo Culture**: This technique involves the culture of embryos, which are also diploid and do not yield haploid plantlets.
- **Berry Stem Culture**: This method involves culturing parts of the stem from berry plants, which are also diploid and not suitable for producing haploid plantlets.

3. **Conclusion**:
- After analyzing the options, the correct method for producing haploid plantlets is **Pollen Culture**.

### Final Answer:
Haploid plantlets can be produced by **Pollen Culture**.
