Hydra reproduces by budding. It is

Options

A. Asexual reproduction
B. Sexual reproduction
C. Parthenocarpy
D. Regeneration.

Answer

To determine how Hydra reproduces, we can analyze the options provided in the question step by step.

### Step 1: Understand Hydra and its Reproductive Methods
Hydra is a simple freshwater organism that belongs to the phylum Coelenterata (also known as Cnidaria). It is known for its ability to reproduce in two primary ways: asexual reproduction and sexual reproduction.

**Hint:** Remember that Hydra is a member of the Coelenterata phylum and is known for its unique reproductive methods.

### Step 2: Identify Asexual Reproduction
Asexual reproduction in Hydra primarily occurs through a process called budding. In this process, a new individual develops from an outgrowth or bud on the parent organism. This method allows Hydra to reproduce without the need for fertilization.

**Hint:** Focus on the term "budding" as it is a key characteristic of asexual reproduction in Hydra.

### Step 3: Consider Sexual Reproduction
While Hydra can also reproduce sexually, this typically occurs under certain conditions, such as environmental stress. In sexual reproduction, Hydra forms specialized structures that develop into ovaries or testes, leading to the production of gametes.

**Hint:** Differentiate between the conditions under which asexual and sexual reproduction occur in Hydra.

### Step 4: Evaluate Other Options
- **Parthenocarpy:** This term refers to the development of fruit without fertilization, which is not applicable to animals like Hydra.
- **Regeneration:** Although Hydra can regenerate lost body parts, this process is not a form of reproduction.

**Hint:** Eliminate options that do not pertain to the reproductive processes of animals.

### Step 5: Conclusion
Based on the analysis, the correct answer to the question "Hydra reproduces by budding. It is" is **asexual reproduction**.

**Final Answer:** Asexual reproduction.
