What is the fate of haploid megaspores formed by the megaspore mother cell in an angiospermic plant?

Explanation

### Step-by-Step Solution:

1. **Formation of Megaspores**: In angiospermic plants, the process begins with the differentiation of a cell in the nucellus into a megaspore mother cell (also known as the megasporangium).

2. **Megasporogenesis**: The megaspore mother cell undergoes megasporogenesis, which involves meiosis. This process results in the formation of four haploid megaspores.

3. **Arrangement of Megaspores**: The four megaspores are arranged linearly.
