flowers and plants used in floral design

What do you think of when you think of flowers?

Today we will…

• Discover the four basic parts of a flower.• Describe the benefit and purpose that

each part has on the flower. • Distinguish between components of

perfect and complete flowers.• Identify the parts or type of flower using

pictures or real flowers.

Identifying Flower Characteristics

• Flowers are important in plant reproduction.• Flowers are necessary in making the seeds from

which plants grow. • Every plant that makes seeds has a unique

flower.• Although many differences occur in flower size,

shape, and color, most flowers have the same basic parts.

Parts of a Flower

• Complete Flowers have four basic parts:• Sepals • Petals• Stamen• Pistil

Sepals

• Sepals are small and green.• They look like leaves.• The sepals cover and protect the flower bud

before it opens.

Petals

• Petals are the showy part of the flower.• Flower petals vary in size, shape, and color.• The bright color and smell of the petals attract

insects to the flower for pollination.

Stamen• The male part of the flower• Each stamen consists of a filament and an

anther.• The filament is a short, slender stalk that

supports the anther.• The anther is a sac-like structure that contains a

yellowish powder called pollen.

Pistil• The pistil is the female part of the flower. • It is located in the center of the flower and is

vase-shaped.• The pistil consists of the stigma, style, and

ovary.

Parts of the Pistil• The stigma is the top part of the pistil that is

sticky which catches and holds pollen. • The style is the tube-like structure that connects

the stigma and the ovary. • The ovary is the enlarged portion at the base of

the pistil. The ovary produces egg cells, which develop into seeds when fertilized.

Incomplete Flowers• Incomplete flowers lack one or more of the four

floral parts. • Perfect flowers may or may not have sepals or

petals, but contain both the stamen and pistil. • Imperfect flowers may or may not have sepals or

petals; they lack either the stamens or pistil.

Activity• Students will travel around the room to different

stations to label the part of the flower or identify if the flower is perfect or complete.

• Each term below will be used once:

• Petal• Stamen• Pistil• Sepal• Anther• Filament• Stigma• Style

• Ovary• Perfect,

Complete Flower

• Perfect, Incomplete Flower

• Imperfect, Incomplete Flower

Review

• What are the four basic parts of a flower?• What is the male part of the flower called, and

what two parts does it consist of?• What is the female part of the flower called, and

what three parts does it consist of? • What is the difference between a perfect and

complete flower?

Today we…

• Discovered the four basic parts of a flower.

• Described the benefit and purpose that each part has on the flower.

• Distinguished between components of perfect and complete flowers.

• Identified the parts or type of flower using pictures or real flowers.
