Section 3.1 Review

Explain the structure and function of each of the four main flower parts.

1)Sepals-leaflike parts that cover and protect the flower bud 2) Petals-modified leaves which are usually bright in color to attract pollinators. 3)Stamens-The pollen-producing male reproductive organ of a flower, consisting of an anther and filament. 4)Pistils-female reproductive parts; found in center; made up of stigma, style, and ovary; stigma is sticky to catch pollen; style moves pollen to ovary

What is the difference between complete and incomplete flowers?

Complete flowers have sepals, petals, and stamens, and pistils Incomplete flowers do NOT have all of those parts.

Flower

reproductive organ of angiosperm plants especially one having showy or colorful parts

Receptacle

enlarged tip of a stem that bears the floral parts

Monoecious

having male and female reproductive organs in the same plant or animal

Long-day plant

Plant that generally requires short nights-- less that 10-12 hours of darkness to begin the flowering process.

Day- neutral Plant

Plants that flower regardless of the length of day.

How are the staminate flowers different from pistillate flowers?

Staminate flowers are flowers which lack pistils and bear only stamens. Pistillate flowers are flowers which lack stamens and only bear pistils

What is the primary purpose of flowers to a plant?

The primary purpose of flowers to a plant is to produce seeds for reproduction.

Photoperiodism

a plant's response to seasonal changes in length of night and day

Pedicel

a small stalk bearing a single flower of an inflorescence

Corolla

collection of petals

Short-day plant

consists of long periods of darkness (about 14 hours) and shorter periods of light

Bract

the bright red structures that appear to be its petals but are actually special leaves

Inflorescence

the flowering part of a plant or arrangement of flowers on a stalk
