Regarding embryoids
(I) Develop form embryonic cells
(II) Develop on cells or explants
(III) Gives rise to plants which produce artificial seed
(IV) Embryogeny resemble that of a sexual embryo

Options

A. I & II Correct
B. II & III correct
C. II & IV correct
D. I && IV correct

Answer

To analyze the statements regarding embryoids, we will evaluate each statement one by one to determine their validity.

### Step-by-Step Solution:

1. **Statement I: Develop from embryonic cells**
- **Analysis**: This statement is incorrect. Embryoids do not develop from embryonic cells; rather, they are formed artificially through tissue culture techniques. They are derived from somatic cells, not specifically embryonic cells.
- **Conclusion**: **False**

2. **Statement II: Develop on cells or explants**
- **Analysis**: This statement is correct. Embryoids can indeed develop from cells or explants, which are pieces of plant tissue used in tissue culture. This process allows for the formation of embryoids from the mass of cells.
- **Conclusion**: **True**

3. **Statement III: Gives rise to plants which produce artificial seeds**
- **Analysis**: This statement is also correct. Embryoids can be used to produce artificial seeds. In plant tissue culture, these embryoids can be coated with a substance that allows them to function as seeds, facilitating the propagation of plants.
- **Conclusion**: **True**

4. **Statement IV: Embryogeny resembles that of a sexual embryo**
- **Analysis**: This statement is incorrect. The embryogeny of embryoids does not resemble that of a sexual embryo. Instead, they are produced through asexual means, specifically through tissue culture, which is different from the natural sexual reproduction process.
- **Conclusion**: **False**

### Final Evaluation:
- The correct statements are **II** and **III**. Therefore, the accurate assessment of the statements regarding embryoids is that only statements II and III are true.
