Seed leaf is

Options

A. Leaf present over the plumule
B. Cotyledon
C. Coleoptile
D. Mesocotyl

Answer

**Step-by-Step Solution:**

1. **Understanding the Seed Structure**:
- A seed consists of an embryo, which is the young plant that will develop after germination.

2. **Identifying the Parts of the Embryo**:
- The embryo has several important structures: the plumule, radical, cotyledons, coleoptile, and coleorhiza.
- The **plumule** is the part that will develop into the shoot system of the plant.
- The **radical** will develop into the root system.

3. **Role of Protective Sheaths**:
- The plumule is covered by a protective sheath known as the **coleoptile**.
- The radical is protected by another sheath called the **coleorhiza**.

4. **Defining Cotyledons**:
- The **cotyledons** are the seed leaves that are part of the embryo. They serve as the first leaves that emerge during germination.
- Cotyledons store food that is utilized by the embryo during germination until the plant can produce its own food through photosynthesis.

5. **Conclusion**:
- Thus, the term "seed leaf" refers specifically to the cotyledons, which are crucial for the initial growth of the seedling.

**Final Answer**: The seed leaf is called the **cotyledon**.
