Mesophyll is not differentiated in the leaf of

Options

A. Nerium
B. Cucurbita
C. Helianthus
D. Triticum

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks which plant has mesophyll that is not differentiated. Mesophyll refers to the tissue in the leaf where photosynthesis occurs, and it can be differentiated into specific types of cells.

2. **Identify Types of Plants**: There are two main types of flowering plants: monocots and dicots. Monocots have one cotyledon in their seeds, while dicots have two.

3. **Characteristics of Mesophyll in Monocots and Dicots**:
- **Monocots**: In monocot plants, the mesophyll is typically not differentiated. This means that the mesophyll cells do not form distinct layers like palisade and spongy mesophyll.
- **Dicots**: In dicot plants, the mesophyll is differentiated into two types of cells: palisade cells (which are tightly packed and located towards the upper side of the leaf) and spongy cells (which are loosely arranged and located towards the lower side).

4. **Analyze the Options**: The question provides several options. We need to identify which of these options is a monocot plant, as only monocots have undifferentiated mesophyll.
- **Neerium**: This is a dicot plant.
- **Cucurbita**: This is also a dicot plant.
- **Helianthus**: This is another dicot plant.
- **Triticum**: This is a monocot plant.

5. **Conclusion**: Since Triticum is the only monocot in the options provided, it is the correct answer to the question. Monocots have mesophyll that is not differentiated.

**Final Answer**: Triticum
