The terms annual, biennial, and perennial describe plant:

• leaf loss

• life cycle

• production practices

• root type

Marigolds and other warm-season plants grow best during:

• early spring

• late fall

• midsummer

• midwinter

Plants that complete their life cycles in two years are:

• annuals

• centennials

• perennials

As part of regular biological processes, a deciduous tree:

• dies each year in the winter

• drops its functional leaves in the dormant season

• keeps its functional leaves in the dormant season

• remains green all year

Because trees live many years, they are:

• annuals

• biennials

• perennials

• semi-annuals

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

• dead

• dormant

• turgid

• millennials

• perennials

If a plant is turgid, it is:

• pale green and yellow

• swollen with moisture

• wilted from lack of water

Annual plants complete their life cycle in:
