What would be the number of chromosomes in the cells of the aleuron layer in a plant species with 8 chromosomes in its synergids?

Options

A. 24
B. 32
C. 8
D. 16

Explanation

To determine the number of chromosomes in the cells of the aleurone layer in a plant species with 8 chromosomes in its synergids, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in Synergids**:
- The problem states that there are 8 chromosomes in the synergids. Synergids are part of the female gametophyte and are haploid (n).
- Therefore, we can denote the haploid number of chromosomes as \( n = 8 \).

2. **Understand the Role of Endosperm**:
- The aleurone layer is part of the endosperm in flowering plants. The endosperm is formed after fertilization and is responsible for nourishing the developing embryo.
- Importantly, the endosperm is triploid (3n), meaning it contains three sets of chromosomes.

3. **Calculate the Chromosome Number in Endosperm**:
- Since we know that \( n = 8 \) (the haploid number), we can find the triploid number by multiplying the haploid number by 3.
- Therefore, the chromosome number in the endosperm (and thus in the aleurone layer) can be calculated as:
\[ 3n = 3 \times 8 = 24 \]

4. **Conclusion**:
- The number of chromosomes in the cells of the aleurone layer is 24.

### Final Answer:
The number of chromosomes in the cells of the aleurone layer is **24**.
