Discuss five examples of vegetative propagation.
Five examples of vegetative propagation are:
(1) Money plant—new plants can grow from stem cuttings when placed in water or moist soil, developing roots and new leaves.
(2) Potato—new plants grow from the 'eyes' or buds of sprouted potatoes when planted in soil.
(3) Ginger—a piece of ginger rhizome planted in soil can grow into a new plant with roots, stems, and leaves.
(4) Sugarcane—new plants grow from stem cuttings when planted, as the nodes contain buds that develop into new plants.
(5) Bamboo—grows from underground stems called rhizomes, with new shoots emerging from nodes.
Vegetative propagation allows plants to reproduce asexually from parts like leaves, stems, or roots without needing seeds, producing new individuals that are exact copies of the parent plant.
Explanation
The chapter defines vegetative propagation as when 'Many plants can reproduce when any part of the plants—leaf, stem, or root—is planted in soil.' Activity 13.3 specifically mentions money plant stem cuttings, potato 'eyes', and ginger as examples. The 'Ever heard of...' section mentions bamboo and sugarcane as plants that grow this way.
Solution Steps
Money plant grows from stem cuttings in water or moist soil, developing roots and leaves
Potato grows from 'eyes' or buds of sprouted potatoes planted in soil
Ginger grows from rhizome pieces planted in soil into new plants with roots, stems, and leaves
Sugarcane grows from stem cuttings via nodes containing buds
Bamboo grows from underground rhizomes with new shoots emerging from nodes
Vegetative propagation is asexual reproduction from plant parts without seeds, producing exact copies of parent
