The single cotyledon in monocots is

Options

A. scutellum which is laterial in position
B. aleurone layeer which is terminal in position
C. scutellum which is centrally placed
D. epiblast which is halpid and lateral in position

Answer

To answer the question "The single cotyledon in monocots is," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Monocots**:
- Monocots, or monocotyledons, are a group of flowering plants that typically have one cotyledon (seed leaf) in their seeds. This distinguishes them from dicots, which have two cotyledons.

2. **Identifying the Cotyledon**:
- In monocots, the single cotyledon is specifically referred to as the **scutellum**. This is a crucial term to remember as it directly answers the question.

3. **Position of the Scutellum**:
- The scutellum is located laterally in the seed, meaning it is positioned to the side rather than centrally. This is important when considering the structure of the seed.

4. **Understanding Other Terms**:
- The term **epiblast** refers to a reduced cotyledon that is haploid and also has a lateral position, but it is not the main cotyledon in monocots.
- The **aleurone layer** is found around the endosperm and is not the cotyledon itself.

5. **Evaluating Options**:
- Based on the definitions and positions discussed, the correct answer to the question is that the single cotyledon in monocots is the **scutellum**, which is laterally positioned.

### Final Answer:
The single cotyledon in monocots is the **scutellum**.
