How many statements are incorrect ?
(i) The function of germ pore is Initiation of the pollen tube.
(ii) The coconut water and edible part of coconut are equivalent to endosperm and endocarp , respectively .
(iii) when pollen is shed at the three-celled stage, syngamy occurs more quickly than the pollen when sheds at two called stage.
(iv) Intine is made up of cellulose and pectin .
(v) pollen grains in some plants remain viable for months .

Options

A. 1
B. 2
C. 3
D. 4

Answer

To determine how many statements are incorrect, we will evaluate each statement one by one.

### Step-by-Step Solution:

1. **Statement (i)**: "The function of germ pore is initiation of the pollen tube."
- **Evaluation**: This statement is **correct**. The germ pore is indeed the site where the pollen tube emerges during the process of fertilization.

2. **Statement (ii)**: "The coconut water and edible part of coconut are equivalent to endosperm and endocarp, respectively."
- **Evaluation**: This statement is **incorrect**. The coconut water is equivalent to the endosperm, but the edible part of the coconut is actually the mesocarp, not the endocarp.

3. **Statement (iii)**: "When pollen is shed at the three-celled stage, syngamy occurs more quickly than when pollen is shed at the two-celled stage."
- **Evaluation**: This statement is **incorrect**. Generally, pollen that is shed at the two-celled stage has a higher chance of successful fertilization compared to the three-celled stage, as it is more prepared for fertilization.

4. **Statement (iv)**: "Intine is made up of cellulose and pectin."
- **Evaluation**: This statement is **correct**. Intine, the inner layer of the pollen wall, is indeed composed of cellulose and pectin.

5. **Statement (v)**: "Pollen grains in some plants remain viable for months."
- **Evaluation**: This statement is **correct**. It is known that pollen grains from certain plants can remain viable for extended periods, sometimes even months.

### Summary of Evaluations:
- Correct Statements: (i), (iv), (v)
- Incorrect Statements: (ii), (iii)

### Conclusion:
Out of the five statements, **two statements are incorrect**.

### Final Answer:
The number of incorrect statements is **2**.
