A plant raised from a single germinating pollen grain under cultural conditions is called a

Options

A. Diploid
B. Haploid
C. Triploid
D. Tetraploid

Answer

To solve the question "A plant raised from a single germinating pollen grain under cultural conditions is called a", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- The question refers to a plant that is raised from a single germinating pollen grain. Pollen grains are the male gametes in plants and are haploid in nature.

2. **Identifying the Process**:
- The process of raising plants from pollen grains is known as androgenesis. This involves the culture of anthers (the part of the stamen that contains pollen) to produce haploid plants.

3. **Defining the Type of Plant**:
- Plants that are produced through androgenesis from haploid microspores or pollen grains are specifically termed as "androgenic haploids".

4. **Analyzing the Options**:
- The options given are diploid, haploid, triploid, and tetraploid. Since the plants are derived from haploid pollen grains, they are also haploid.

5. **Conclusion**:
- Therefore, the correct answer to the question is "haploid".

### Final Answer:
A plant raised from a single germinating pollen grain under cultural conditions is called a **haploid**.
