The number of chromosomes present in the cells of the bread wheat, Triticum aestivum suggests that it is

Options

A. Hexaploid
B. diploid
C. tetraploid
D. pentaploid.

Answer

To solve the question regarding the number of chromosomes present in the cells of bread wheat (Triticum aestivum), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Scientific Name**: The question mentions "bread wheat," which is scientifically known as Triticum aestivum.

2. **Understand Chromosome Number**: In botany, the chromosome number is crucial for understanding the ploidy level of an organism. Ploidy refers to the number of sets of chromosomes in a cell.

3. **Determine the Ploidy Level of Triticum aestivum**: Bread wheat is known to be a hexaploid organism. This means it has six sets of chromosomes.

4. **Know the Chromosome Count**: The specific chromosome count for Triticum aestivum is 2n = 6x = 42. Here, "2n" represents the diploid number, "6x" indicates hexaploidy, and "42" is the total number of chromosomes.

5. **Conclude the Answer**: Based on the information that Triticum aestivum is hexaploid with 42 chromosomes, we conclude that the correct answer to the question is "hexaploid."

### Final Answer:
The number of chromosomes present in the cells of bread wheat, Triticum aestivum, suggests that it is hexaploid.
