In castor proliveration of the outer integumentary cells at micropylar region

Options

A. lacks hygroscopic ability
B. attarct ants and heps in myrmecophily
C. is called epiblast
D. stores sugary substances

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question pertains to the proliferation of outer integumentary cells at the micropylar region in castor seeds. We need to identify the correct statement regarding this phenomenon.

2. **Analyzing the Options**:
- **Option 1**: "Lack hydroscopic ability" - This option suggests that the outer integumentary cells do not have the ability to absorb water. This is incorrect because the micropylar region plays a crucial role in the absorption of water and oxygen, which are essential for seed germination.

- **Option 2**: "Attract ants and help in myrmecophily" - This option implies that the outer integumentary cells aid in attracting ants for pollination. However, this is not relevant to the question about seed proliferation and is therefore incorrect.

- **Option 3**: "Is called epiblast" - The term epiblast refers to a structure in monocots and is not related to the outer integumentary cells in the context of the micropylar region. Thus, this option is also incorrect.

- **Option 4**: "Stores sugary substances" - This statement is accurate. The micropylar region contains a structure known as the caruncle, which stores sugary substances. These sugars are important for attracting animals (like ants) that help in seed dispersal.

3. **Conclusion**: After analyzing all the options, the correct answer is that the outer integumentary cells at the micropylar region in castor seeds store sugary substances, which is associated with the caruncle.

**Final Answer**: The correct option is 4, which states that the outer integumentary cells at the micropylar region store sugary substances.
