The correct Answer is:
To solve the question regarding the statements about pollen grain cells, we will evaluate each statement one by one based on our understanding of pollen grain structure and function. ### Step-by-Step Solution: 1. **Evaluate Statement 1**: "The vegetative cell has an abundant food reserve." - **Analysis**: The vegetative cell is known to store nutrients that support the generative cell. Therefore, this statement is **True**. 2. **Evaluate Statement 2**: "The vegetative cell has a large irregularly shaped nucleus." - **Analysis**: The vegetative cell indeed contains a large, irregularly shaped nucleus. Thus, this statement is also **True**. 3. **Evaluate Statement 3**: "The generative cell is small and is fixed in the cytoplasm of the vegetative cells." - **Analysis**: While the generative cell is small, it is not fixed in the cytoplasm; it floats within it. Therefore, this statement is **False**. 4. **Evaluate Statement 4**: "The generative cell is spindle-shaped and has dense cytoplasm." - **Analysis**: The generative cell is typically spindle-shaped and does have dense cytoplasm. Thus, this statement is **True**. ### Summary of Evaluations: - Statement 1: True - Statement 2: True - Statement 3: False - Statement 4: True ### Final Answer: The correct combination of true and false for the given statements is: - (1) True - (2) True - (3) False - (4) True
