plant growth and development

Plant growth is

• dry weather

• size increase by cell division and enlargement

• size increase by vegetative state

• seed germination

Plant development is the plants ...

• progress through its lifecycle

• ability to withstand heat

• progress through its germination

• ability to be diverse

Apical meristems are

• vegetative buds at the shoot tips

• in the axils of leaves
