Mass of cell enclosed within the integuments in ovule is called

Options

A. Chalaza
B. Endosperm
C. Nucellus
D. Sporogenous tissue

Answer

To solve the question "Mass of cell enclosed within the integuments in ovule is called," we can follow these steps:

### Step 1: Understand the Components of the Ovule
The ovule is a structure found in seed plants that develops into a seed after fertilization. It consists of several parts, including the integuments, nucellus, chalaza, and others.

### Step 2: Identify the Role of Each Component
- **Chalaza**: This is the region where the integuments and the nucellus are attached. It does not refer to the mass of cells itself.
- **Endosperm**: This is the tissue that provides nourishment to the developing embryo, but it is not enclosed within the integuments.
- **Nucellus**: This is the central part of the ovule and is made up of parenchyma cells. It is indeed the mass of cells that is enclosed within the integuments and contains the embryo sac.
- **Sporogenesis Tissue**: This refers to the tissue that produces pollen grains and is not related to the ovule's structure.

### Step 3: Determine the Correct Answer
Based on the definitions and roles of the components, the mass of cells enclosed within the integuments of the ovule is called the **nucellus**.

### Conclusion
The correct answer to the question is **nucellus**.
