In flowering plants, haustorial cell is

Options

A. The cell of suspensor present at the micropylar end and formed during embryogenesis.
B. The cell of suspensor present at the chalazal end and formed during embryogenesis.
C. The cell of suspensor present at the micropylar end and formed during the formation of the endosperm.
D. The cell of suspensor present at the chalazal end and formed during the formation of the endosperm.

Answer

To solve the question "In flowering plants, haustorial cell is?", we will analyze the options provided and determine which one correctly describes the haustorial cell.

### Step-by-Step Solution:

1. **Understanding Haustorial Cells**:
- Haustorial cells are specialized cells in flowering plants that are involved in the absorption of nutrients. They typically develop in the context of the embryo and endosperm.

2. **Evaluating the Options**:
- **Option 1**: "The cell of the suspension present at the micropilar end and form during the embryo."
- This option suggests that the haustorial cell is associated with the micropilar end of the embryo and forms during embryogenesis. This aligns with the definition of haustorial cells as they are involved in nutrient absorption during the early stages of plant development.

- **Option 2**: "The cell of suspension present at the micropilar end and form during the formation of the endosperm."
- This option is incorrect because haustorial cells are not primarily associated with the endosperm formation but rather with the embryo development.

- **Option 3**: "The cell of the suspension present at the chalazal end."
- This option is also incorrect as it misplaces the location of the haustorial cell. The haustorial cells are typically found at the micropilar end, not the chalazal end.

3. **Conclusion**:
- Based on the analysis of the options, the correct answer is **Option 1**: "The cell of the suspension present at the micropilar end and form during the embryo."

### Final Answer:
In flowering plants, haustorial cell is the cell of the suspension present at the micropilar end and forms during the embryo.
