Answer 4

Removing pieces of a plant and growing them into new individuals
EXAMPLE IN PLANTS
- the tip of the stems and side shoots are removed from the plant to be cloned (explant)
- the explants are trimmed
- placed in medium with nutrients and hormones to encourage growhth
- the explants with shoots taken from new shoots that form on original ones
- the explants with shoots are transferred to another culture medium containing different hormones to induce root formation
- when explants grow roots, they’re transferred to greenhouses and transplanted into compost.
