The diploid parenchymatous mass of cells which constitutes the body of the young ovule of Pinus is called

Options

A. Endosperm
B. Perisperm
C. Nucellus
D. Nucellar beak.

Answer

To answer the question regarding the diploid parenchymatous mass of cells that constitutes the body of the young ovule of Pinus, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Ovule**:
- The ovule is a structure that develops into a seed after fertilization. In gymnosperms like Pinus, the ovule contains several important components.

2. **Identifying the Key Terms**:
- The question mentions "diploid parenchymatous mass of cells." This indicates that we are looking for a tissue that is composed of diploid cells and has a parenchymatous (soft and flexible) structure.

3. **Reviewing the Options**:
- The options provided are:
- A) Androsperm
- B) Perisperm
- C) Nucellus
- D) Nucellar beak

4. **Analyzing Each Option**:
- **Androsperm**: This term refers to the male gametophyte and is not relevant to the ovule structure.
- **Perisperm**: This is a tissue that provides nourishment to the developing embryo but is not the main body of the ovule.
- **Nucellus**: This is the central part of the ovule, which is indeed a diploid tissue that provides nourishment and support to the developing embryo.
- **Nucellar beak**: This structure is typically found in some dicots and is not relevant to Pinus.

5. **Selecting the Correct Answer**:
- Based on the analysis, the correct answer is **C) Nucellus**. The nucellus is the diploid parenchymatous mass of cells that constitutes the body of the young ovule in Pinus.

### Conclusion:
The diploid parenchymatous mass of cells which constitutes the body of the young ovule of Pinus is called **nucellus**.
