Why are budding, fragmentation and regeneration all considered as asexual types of reproduction? With neat diagrams explain the process of regeneration in Planaria.

Explanation

### Step-by-Step Solution:

**Step 1: Understanding Asexual Reproduction**
- Asexual reproduction is a mode of reproduction that involves only one parent. In this process, offspring are produced without the fusion of gametes (sperm and egg).
- The offspring are genetically identical to the parent and each other, making them clones.

**Step 2: Identifying Asexual Reproductive Processes**
- **Budding**: A small outgrowth (bud) forms on the parent organism. This bud eventually detaches and grows into a new individual. Example: Hydra.
