Question

When a seed of an orange is squeezed, many embryos, instead of one are observed. Explain how it is possible.

Answer 1

it is due to polyembryony. 

Occurrence of more than one embryo in a seed is called as polyembryony. 

In orange, the nucellar cells, synergid or integument cells develop into a number of embryos of different sizes. e.g., Citrus. 

Sometimes formation of more than one egg in an embryo,  sac can lead to polyembryony.
