The ....cell is bigger , has abundant food reserve and a large irregularly shape nucleus. The ..... is small and has a spindle-shaped nucleus with dense cytoplasm.

Options

A. a - vegetative cell, b - generative cell
B. a - generative cell, b-vegetative cell
C. a - tapetal cell, b- endothelial cell
D. a - endothelial cell, b-tapatal cell

Answer

To solve the question, we need to identify the two types of cells being described based on their characteristics.

### Step-by-Step Solution:

1. **Identify the Characteristics of the First Cell:**
- The first cell is described as "bigger," has "abundant food reserve," and possesses a "large irregularly shaped nucleus."
- These characteristics are typical of a **vegetative cell** found in pollen grains. The vegetative cell serves as a source of nutrition and support for the generative cell.

2. **Identify the Characteristics of the Second Cell:**
- The second cell is described as "small," has a "spindle-shaped nucleus," and contains "dense cytoplasm."
- These features are characteristic of a **generative cell**, which is smaller than the vegetative cell and is responsible for producing sperm cells during fertilization.

3. **Conclusion:**
- Based on the characteristics provided, the first cell is identified as a **vegetative cell** and the second cell as a **generative cell**. Both of these cells are components of pollen grains.

### Final Answer:
The first cell is a **vegetative cell**, and the second cell is a **generative cell**.
