Mention the ploidy of the following:
primary endosperm nucleus in dicot

Explanation

To determine the ploidy of the primary endosperm nucleus in dicots, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Embryo Sac**: In dicots, the embryo sac typically contains several types of cells, including antipodal cells, synergids, and egg cells.

2. **Identify the Ploidy of Different Cells**:
- Antipodal cells: These are haploid (n).
