Knowledge Plus Vegetative Propagation
When plants reproduce with the help of
The process by which a seed produces their body parts such as roots, stems
a new plant is called germination. and leaves and not through seeds, it is

called vegetative propagation.

Reproduction by Roots

Radish, carrot, turnip and sweet potato are

the roots that store food in them. They are
swollen because of stored food and are

called tuberous roots . When these roots are
planted in soil, they give rise to new plants.

Reproduction by Stems

Ginger, onion and potato are underground
stems. They also have stored food in them.
Reproduction by leaves in
Bryophyllum and Begonia These stems bear buds from which new
plants can grow.
Reproduction by Leaves

Some plants have leaves which develop

buds on their margins. These buds develop
into plantlets which later separate out from

the parent plant and grow into new plants.
Begonia and Bryophyllum plants reproduce
Cactus and Rose are grown
by stem cutting in this manner.

Reproduction
Some plants like the rose, sugarcane and hibiscus grow from stem cuttings.

This piece of stem is then planted into the soil and watered regularly. After
few days, it develops roots and buds and grows into a new plant.

STRUCTURE OF A FLOWER

A flower has four parts, that are sepals, petals, stamens and pistil.

Sepals are green, small, leaf like structures at the base of the flower. They
protect the developing bud.

Petals are bright coloured parts of the flower. They are bright and attract

insects for the pollination.
