An embryo may sometimes develop from any cell of embryo sac other than egg.It is termed as

Options

A. apospory
B. apogamy
C. parthenogenesis
D. parthenocarpy

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the development of an embryo from any cell of the embryo sac other than the egg. This indicates a form of reproduction that does not involve the typical fertilization process.

2. **Analyzing the Options**:
- **Option A: Apospory**: This refers to the formation of a diploid gametophyte from the sporophyte without meiosis. It does not fit the question since it does not involve the embryo sac directly.
- **Option B: Apogamy**: This is the process where an embryo develops without the fusion of gametes (egg and sperm). This directly relates to the question as it involves the development of an embryo from cells other than the egg.
- **Option C: Parthenogenesis**: This is the development of an unfertilized egg into a complete individual. While it involves an egg, it does not fit the criteria of developing from other cells in the embryo sac.
- **Option D: Parthenocarpy**: This refers to the development of seedless fruits, which is unrelated to embryo development from the embryo sac.

3. **Identifying the Correct Answer**: After analyzing all options, **Option B: Apogamy** is the correct answer. It describes the process where an embryo can develop from cells other than the egg without the fusion of gametes.

### Final Answer:
The correct term for the development of an embryo from any cell of the embryo sac other than the egg is **Apogamy**.
