Normally one embryo develops in one seed but when an orange seed is squeezed many embryos of different shapes and sizes are seen. Mention how it has happened.

Explanation

### Step-by-Step Solution:

1. **Understanding Seed Development**: Normally, in most plants, a single embryo develops within a seed. This is the standard process of seed formation where one ovule gives rise to one embryo.

2. **Observation in Orange Seeds**: When an orange seed is squeezed, multiple embryos of various shapes and sizes can be observed. This is an unusual phenomenon that deviates from the typical seed development process.

3. **Role of Nucellus**: In the case of orange seeds, the phenomenon can be attributed to the nucellus, which is a tissue within the ovule. The nucellus contains cells that can undergo division.
