In grasses, epicotyl has a shoot apex & a few leaf primordia enclosed in a ____________ foliar structure, called as_______

Options

A. Hollow, Coleorhiza
B. Solid, Coleoptile
C. Hollow, Coleoptile
D. Solid, Coleorhiza

Answer

To answer the question, we need to fill in the blanks regarding the structure enclosing the shoot apex and leaf primordia in grasses.

### Step-by-Step Solution:

1. **Understanding the Structure**: In grasses, the epicotyl is the part of the seedling that develops into the shoot. It contains the shoot apex (the growing tip of the plant) and a few leaf primordia (the early stages of leaves).

2. **Identifying the Foliar Structure**: The question asks for the type of foliar structure that encloses the shoot apex and leaf primordia. In grasses, this structure is known for being protective and facilitating the emergence of the first leaf.

3. **Correct Term for the Structure**: The correct term for this enclosing structure is "coleoptile". The coleoptile is a hollow, foliar structure that protects the shoot apex and the leaf primordia as they grow.

4. **Filling in the Blanks**: Therefore, the complete answer to the question is:
- In grasses, the epicotyl has a shoot apex and a few leaf primordia enclosed in a **hollow** foliar structure, called as **coleoptile**.

### Final Answer:
In grasses, epicotyl has a shoot apex & a few leaf primordia enclosed in a **hollow** foliar structure, called as **coleoptile**.
