Vegetative propagation

The idea

In vegetative propagation, parts of a plant such as the root, stem or leaves develop into new plants under appropriate conditions.

Plants without seeds

A gardener plants a piece of a plant, not a seed, and a new plant grows.

Which parts of a plant can grow into a new plant?

• Root, stem or leaves
• Only the flower
• Nothing, a seed is always needed

A part becomes a plant

New plants from old parts

Plants can use this way to reproduce, unlike most animals. Methods such as layering or grafting use it to grow sugarcane, roses and grapes. Bryophyllum does it by itself with the buds on its leaves.

Notes

In vegetative propagation, the root, stem or leaves of a plant develop into new plants under appropriate conditions.

Which plants are grown by methods such as layering or grafting, as the book mentions?

• Only the flower. The book names parts like the root, stem and leaves.
• Root, stem or leaves — correct. Yes!
• Only the seed. Vegetative propagation uses plant parts such as root, stem or leaves, not seeds.
• They turn into new leaves on the same plant. The book says they fall on the soil and develop into new plants.
• They dry up and nothing grows from them. The buds fall on the soil and develop into new plants.
• They fall on the soil and develop into new plants — correct. Yes!
• Sugarcane, roses and grapes — correct. Yes!
• Hydra and Planaria. Hydra and Planaria are animals that can regenerate. The book names sugarcane, roses and grapes for layering and grafting.
• Rhizopus and yeast. Rhizopus forms spores and yeast puts out buds. They are not the plants named for layering or grafting.
