Embryoids are

Options

A. Somatic embryo-like structures
B. Small embryos through fertilisation in culture
C. Early embryho stages used for Propagation in tissue culture
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Embryoids":**
- Embryoids refer to structures that resemble embryos but are not formed through the typical fertilization process. They are often created in laboratory settings through tissue culture.

2. **Identifying Characteristics of Embryoids:**
- Embryoids are typically non-zygotic and can develop from somatic cells (vegetative cells) rather than from fertilized eggs.
- They have the potential to develop into full plants, similar to normal embryos.

3. **Analyzing the Options Provided:**
- **Option A:** Somatic embryo-like structures - This aligns with the definition of embryoids as they are derived from somatic cells.
- **Option B:** Small embryos through fertilization and culture - This is not accurate for embryoids, as they do not arise from fertilization.
- **Option C:** Early embryo stages used for propagation in tissue culture - While embryoids can be used in tissue culture, this option is too vague and does not specifically define embryoids.
- **Option D:** All of the above - Since options B and C are not entirely accurate descriptions of embryoids, this option cannot be correct.

4. **Conclusion:**
- Based on the definitions and characteristics discussed, the correct answer to the question "Embryoids are" is **Option A: somatic embryo-like structures**.
