Horticulture 1 Objectives 1-4

Marigolds and other warm-season plants grow best during:

• early spring

• midsummer

• late fall

• midwinter

As part of regular biological processes, a deciduous tree:

• dies each year in the winter.

• keeps its functional leaves in the dormant season.

• drops its functional leaves in the dormant season.

• remains green all year.

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

• deciduous

• evergreen

• herbaceous

• turgid

Because trees live many years, they are:

• annuals

• biennials

• perennials

• semiannuals

The terms annual, biennial, and perennial describe plant:

• leaf loss

• life cycle

• production practices

• leaf type

Trees that keep their functional leaves throughout the year are:

• auxins

• deciduous

• evergreen

• inhibitors

Annual plants complete their life cycle in

• one year

• two years

• three years

• ten years

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

• annuals

• biennials

• millenniums

• perennials

If a plant is turgid, it is:

• drowned and drooping

• pale green or yellow.

• swollen with moisture.

• wilted from lack of water.

Plants that complete their life cycles in two years are:

• annuals

• biennials

• minerals

• perennials
