Model Answer
Stages of Budding in Hydra:
```
Stage 1 Stage 2 Stage 3
Hydra Bud growing Bud detaches
| |
[Parent] [Parent] [Parent] [New Hydra]
| + Bud (separate individual)
```
- Stage 1: A small outgrowth (bud) appears on the parent Hydra due to repeated cell division.
- Stage 2: The bud grows and develops tentacles, becoming a tiny individual.
- Stage 3: The fully mature bud detaches from the parent body and becomes a new independent individual.
(Labelled diagram should show: Parent Hydra, Bud, Tentacles, Detached new Hydra)

Explanation
- This question is diagram-based, so drawing is mandatory — describe what to label if drawing on paper.
- Three stages must be shown: bud initiation → bud development with tentacles → detachment.
- Key labels: Parent body, Bud, Tentacles, Detached Hydra.
- Examiners award 1 mark for correct stages and 1 mark for proper labels. Do not omit labels.
