Principles and Elements of Floral Design Parts of a Flower Principles and Elements of Floral Design TEKS C (1) (b) Classify and identify 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 Ovary Stamen Perfect, Complete Flower Pistil Sepal Perfect, Incomplete Flower Anther Filament Stigma Imperfect, Incomplete Flower Style

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.
