Considering the reproductive processes in organisms which statements is not correct?

Options

A. Offspring produced by the asexual reproduction are called clone
B. Microscopic, motile asexual reproductive structures are called zoospores
C. In potato, banana and ginger, the plantlets arise from the internodes present in the modified stem
D. Water hyacinth, growing in the standing water, drains oxygen from water that leads to the death of fishes

Explanation

To determine which statement regarding reproductive processes in organisms is not correct, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement 1**: "The offsprings which are produced by asexual reproduction are called as clones."
- **Analysis**: This statement is true. Clones are genetically identical individuals produced from a single parent through asexual reproduction. They arise from mitotic cell division.

2. **Statement 2**: "The microscopic motile asexual reproductive structures are called as zoospores."
- **Analysis**: This statement is also true. Zoospores are indeed motile asexual reproductive structures found in certain algae and fungi. They possess flagella, allowing them to move.

3. **Statement 3**: "In potato, banana and ginger the plantlets arise from internodes present in modified stem."
- **Analysis**: This statement is false. In potatoes, the plantlets arise from the eyes (nodes) of the tuber, while in bananas and ginger, they arise from the nodes of rhizomes. Therefore, they do not arise from the internodes.

4. **Statement 4**: "The water hyacinth (Eichhornia crassipes), growing in standing water, drains oxygen from the water that leads to the death of the fishes."
- **Analysis**: This statement is true. Water hyacinth grows rapidly and can deplete oxygen levels in the water, which can be detrimental to fish and other aquatic life.

### Conclusion:
The incorrect statement is **Statement 3**.

### Final Answer:
The statement that is not correct is: "In potato, banana and ginger the plantlets arise from internodes present in modified stem."
