Structure similar to transfer cells occurs in

Options

A. antipodal cells
B. central cell of embryo sac
C. filiform apparatus of oosphere and synergids.
D. all the above.

Answer

To answer the question "Structure similar to transfer cells occurs in," we will analyze each option provided and determine which one is correct based on the characteristics of transfer cells.

### Step-by-Step Solution:

1. **Understanding Transfer Cells**:
Transfer cells are specialized plant cells that facilitate the movement of nutrients and solutes. They typically have thickened cell walls and numerous infoldings that increase the surface area for transport.

2. **Analyzing Option A: Antipodal Cells**:
- Antipodal cells are located at the opposite end of the embryo sac and play a role in nourishing the egg cells. However, they do not have the specialized structure or function of transfer cells, which are primarily involved in nutrient transfer.

**Hint**: Consider the primary function of antipodal cells and whether it aligns with nutrient transfer.

3. **Analyzing Option B: Central Cell of Embryo Sac**:
- The central cell is responsible for forming triploid endosperms upon fertilization. It does not actively transport nutrients like transfer cells do, as its primary role is related to reproduction rather than nutrient movement.

**Hint**: Focus on the role of the central cell in reproduction rather than nutrient transfer.

4. **Analyzing Option C: Filiform Apparatus of Oosphere and Synergids**:
- The filiform apparatus is located in the synergids, which are adjacent to the egg cell. This structure is crucial for guiding the pollen tube and is involved in the transfer of nutrients to the egg cell. The synergids, along with the filiform apparatus, exhibit characteristics similar to transfer cells, such as thickened walls and the ability to facilitate nutrient movement.

**Hint**: Think about the role of the filiform apparatus in nutrient transfer and its structural similarities to transfer cells.

5. **Analyzing Option D: All of the Embryo**:
- This option is too broad. While various parts of the embryo may have different functions, not all structures in the embryo are similar to transfer cells.

**Hint**: Evaluate whether "all of the embryo" can be classified under the specific function of transfer cells.

### Conclusion:
Based on the analysis, the correct answer is **C: Filiform apparatus of oosphere and synergids**, as it shares structural and functional similarities with transfer cells.
