Which of the following statement is not correct?

Options

A. Fungi multiply and spread easily due to production of large number of asexual spore
B. Yeast and Hydra reproduce by budding
C. In Planaria asexual reproduction takes place by budding
D. Fungi and Algae can easily multiply by fragmentation

Answer

To determine which statement is not correct among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement 1: Fungi multiply and spread easily due to the production of a large number of asexual spores.**
- **Analysis:** This statement is correct. Fungi reproduce asexually by producing a large number of spores, which allows them to spread easily in their environment.

2. **Statement 2: Yeast and Hydra reproduce by budding.**
- **Analysis:** This statement is also correct. Both yeast (a type of fungus) and Hydra (a simple aquatic animal) reproduce asexually through a process called budding, where a new organism develops from a bud on the parent organism.

3. **Statement 3: In planaria, asexual reproduction takes place by budding.**
- **Analysis:** This statement is incorrect. Planaria, a type of flatworm, primarily reproduce asexually through fission, not budding. During fission, the organism splits into two or more parts, and each part can regenerate into a complete organism.

4. **Statement 4: Fungi and algae can easily multiply by fragmentation.**
- **Analysis:** This statement is correct. Both fungi and certain algae can reproduce asexually through fragmentation, where parts of the organism break off and grow into new individuals.

### Conclusion:
The statement that is not correct is **Statement 3: In planaria, asexual reproduction takes place by budding.**
