1. Rhizome
2. Bulb
3. Corm
4. Tuber
5. None of the above/More than one of the above.

Answer 1

Correct Answer - Option 1 : Rhizome

The correct answer is Rhizome.

• The rhizome is a type of Vegetative propagation of asexual reproduction.
• Vegetative propagation is a mode of reproduction in which new plants are formed from vegetative parts (vegetative propagules) of the plant-like root, stem, etc.
• Since the formation of these vegetative propagules does not involve two parents, the process involved is asexual.
• It is very common in higher angiosperms.
• Following are some units of vegetative propagation:
  • Rhizome - Ginger
  • Bulb - Onion, Garlic
  • Tuber - potato
  • Bulbil - Agave
  • Leaf buds - Bryophyllum
  • Offset - Hyacinth and pistia
  • Runner - Oxalis
  • Sucker - Mint

Explanation-

• A rhizome is a form of plant stem that consists of nodes from which roots and shoots emerge. 
• Rhizomes can be found on the surface of the soil or underneath.
• Rhizomes are distinguished by their steep growth, which allows new shoots to emerge from the ground. 
• When a rhizome is separated, each component is capable of growing a new plant.
• Example-  As in Ginger, Rhizome is capable of giving rise to new offspring.
