Describe the methods of natural vegetative propagation in plants.

Natural vegetative propagation occurs when plants reproduce from vegetative parts like stems, roots, or leaves.

1. Runners (Stolons):

Horizontal stems that grow along the soil surface and produce new plants at nodes.

Example: Strawberry, Grass.

2. Tubers:

Swollen underground stems that store food and produce new shoots.

Example: Potato.

3. Bulbs:

Underground storage organs consisting of fleshy leaves surrounding a central bud.

Example: Onion, Garlic.

4. Rhizomes:

Underground horizontal stems that develop new shoots and roots at nodes.

Example: Ginger, Bamboo.
