Trees that keep their functional leaves throughout the year are:

• auxins

• deciduous

• evergreen

• inhibitors

Marigolds and other warm-season plants grow best during

• early spring

• late fall

• midsummer

• midwinter

Plants that take three or more years to complete their life cycle are:

• annuals

• biennials

• smillenniums

• perennials

Most cool-season grasses grow very little during the hottest months of summer. what is this condition called?

• dead

• dormant

• turgid

• wilted

Plants that complete their life cycles in two years are:

• annuals

• biennials

• centennials

• perennials

In North Carolina, a tree that has no leaves in the winter is:

• deciduous

• evergren

• herbaceous

• turgid

The terms annual, and perennial describe plant:biennial,

• leaf loss

• life cycle

• production practices

• root type

Annual plants complete their life cycle in:

• one year

• two years

• three years

• ten years

If a plant is turgid, it is:

• drowned and drooping

• pale green or yellow

• swollen with moisture

• wilted from lack of water

Because trees live many years, they are:

• annuals

• bienials

• perennials

• semiannuals
