4.12 : Vegetative Reproduction Plant parts Used in Vegetative Reproduction

•  Vegetative reproduction : Production of new plants using any parts of a plant except seed

•  A form of asexual reproduction as no gametes are used

•  Carried out in different ways using different parts of plants

LEAVES

•  Some plants form buds at the edge of their leaves

•  The buds grow into new plants

•  Examples: – Bryophyllum – Begonia – Mother-in-

law’s tongue

4.12 : Vegetative Reproduction CREEPING STEMS

•  Long stems which creep along the ground.

•  Shoots & roots grow at the nodes & become new plants

•  Examples : – Grass – Sweet potato – Strawberry

4.12 : Vegetative Reproduction STEM CUTTINGS

•  Short stems containing buds at the nodes are cut & planted

•  The buds develop into new plants

•  Examples : – Sugar cane – Tapioca – Rose

4.12 : Vegetative Reproduction BULBS

•  Bulbs : Short, vertical underground stems surrounded by the swollen bases of the leaves

•  New buds grow from the axils of the swollen leaves

•  Examples : – Onions – Spider lily – Garlic

4.12 : Vegetative Reproduction RHIZOMES

•  These horizontal underground stems which store food

•  They produce buds at the nodes

•  Examples : – Ginger – Canna lily – Lallang

4.12 : Vegetative Reproduction TUBERS •  Swollen ends of

underground stems which store food

•  Buds form on the swollen ends of the stems

•  Examples : – English potato – Dahlia

4.12 : Vegetative Reproduction CORMS

•  Short erect underground stems which store food

•  Stems are solid & not surrounded by leaf bases as in bulbs

•  Examples: – Yam – Water chestnut – Sengkuang

4.12 : Vegetative Reproduction SUCKERS

•  Young shoots grow up from a short underground stem

•  The shoots can be separated from the parent plant and develop into new plants

•  Examples : – Bamboo – Banana – pineapple

4.12 : Vegetative Reproduction Advantages of Vegetative Reproduction

•  New plants grow much faster than those grown from seeds

•  New plants can obtain food from the parent plants until they can make their own food

•  Good qualities of the parent plant are inherited

•  Does not require agents of pollination

•  Does not need fertilization as no gametes are used
