Transcript Lesson 01b Parts of a Flower PPT

Principles and Elements of Floral Design
TEKS C (1) (b) Classify and identify flowers
and plants used in floral design
• 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.
• 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.
• Complete Flowers have four basic parts:
• Sepals
• Petals
• Stamen
• Pistil
• Sepals are small and green.
• They look like leaves.
• The sepals cover and protect the flower bud
before it opens.
• 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.
• 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.
• The pistil is the female part of the flower.
• It is located in the center of the flower and is vaseshaped.
• The pistil consists of the stigma, style, and ovary.
• 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 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.
• 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.
