Can an unfertilised, apomictic embryo sac give rise to diploid embryo ? If yes, then how ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Apomixis**: Apomixis is a form of asexual reproduction that occurs in some flowering plants, where seeds are produced without fertilization. In this process, the embryo sac can develop into an embryo without the need for fertilization by pollen.

2. **Normal Embryo Development**: In typical sexual reproduction, a diploid megaspore mother cell undergoes meiosis to produce haploid megaspores. These megaspores then divide mitotically to form the egg cell, which is also haploid. After fertilization, this haploid egg cell develops into a diploid embryo.

3. **Formation of Diploid Embryo in Apomixis**: In the case of apomixis, the process differs. The megaspore mother cell does not undergo meiosis. Instead, it remains diploid and directly produces diploid megaspores.
