Answer 1

Rhizome is an underground stem modification. The terminal bud of rhizome may or may not grow into an aerial shoot. The stem is differentiated into nodes and internodes. Adventitious root occurs on the lower side. For example, ginger.

Water Hyacinth or eichhornia propagates by offsets. An offset is a short thick runner like branch which produces a new plant at its tip. The offsets grow in all directions from the main stem of the parent plant.

Sucker is a mode of vegetative propagation. It is a non- green slender stem branch which arises from the underground base of erect shoot or crown. It grows horizontally in the soil and ultimately comes out to form a new arial shoot or crown. Each sucker has nodes with scale leaf and axillary bud. For example, chrysanthemum is propagated vegetatively either through root suckers or terminal cuttings.

Bryophyllum is multiplied vegetatively by leaf buds. The leaves of the Bryophyllum has a bud in the notch which when falls on the moist soil, germinates into a plant. The notch are meristematic in nature which has the potential to germinate into new plant.
