if the diploid number of flowering plant is 36, what would be the chromosome number in its endosperms?

Options

A. 36
B. 18
C. 54
D. 72

Explanation

To solve the question regarding the chromosome number in the endosperm of a flowering plant with a diploid number of 36, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Diploid Number (2n)**:
The diploid number of the flowering plant is given as 36. This means that the plant has two sets of chromosomes, one from each parent.

2. **Calculate the Haploid Number (n)**:
The haploid number is calculated by dividing the diploid number by 2.
\[ n = \frac{2n}{2} = \frac{36}{2} = 18 \]
So, the haploid number (n) is 18.

3. **Understand the Endosperm's Chromosome Number**:
The endosperm in flowering plants is typically triploid (3n). This means it has three sets of chromosomes.

4. **Calculate the Triploid Number (3n)**:
To find the chromosome number in the endosperm, we use the formula for triploid:
\[ 3n = n + n + n = 2n + n = 36 + 18 = 54 \]
Therefore, the chromosome number in the endosperm is 54.

5. **Final Answer**:
The chromosome number in the endosperm of the flowering plant is 54.
