This document provides information about the parts of flowers. It begins by stating the objective is to identify the important parts of a flower needed for seed development. It then describes several learning activities and assessments for students to complete to learn about flower parts, including identifying the main parts of flowers and grouping flowers by their completeness. The document provides diagrams and explanations of the main parts of flowers, including the pistil, stamen, petals, and sepals. It also distinguishes between complete and incomplete flowers as well as perfect and imperfect flowers. Students are prompted to answer questions to test their understanding and provide feedback on the difficulty of the tasks. References and resources for further learning are also listed.

Small flowers and seeds are found in so many varieties that you
may not be able to know them all in your lifetime.
A flower, sometimes known as a bloom or blossom, is the
reproductive structure found in flowering. The biological function
of a flower is to effect reproduction, usually by providing a
mechanism for the union of sperm with eggs. Flowers may
facilitate outcrossing or allow selfing Some flowers produce
diaspores without fertilization (parthenocarpy).

3. 1. Observe the
diagram of the
flower.
2. Identify the four
important parts of
the flower
according to the
labeled parts of the
diagram of a
typical flower.
Usually, the top of the stem forms the
base that supports the flower. There are
green leaf like covering at the base of the
flower called sepals. A group of sepals is
called calyx. This protects the flower
while it still a bud. The stamen is the
male reproductive organ of the flower.
It’s part are the filament and anther. The
anther carries the pollen grains. The
pistil is the female part of the flower. It is
composed of the stigma, the style and the
ovary. The flower is the reproductive
organ of the plants. Petals are the colored
structures of the flower. Some are
brightly colored and some are fragrant to
attract insects. People are also attracted
to flowers. They appreciate beautiful
flowers and usually use flower for
various.

11. The Basic Flower Parts
The flower consists of many different parts. Some of the most important parts being separated into both male and female parts.
Male Parts
Stamen
This is the male part of the flower. It is made up of the filament and anther, it is the pollen producing part of the plant. The number of stamen is usually the same as the number of petals.
Anther
This is the part of the stamen that produces and contains pollen. It is usually on top of a long stalk that looks like a fine hair.
Filament
This is the fine hair-like stalk that the anther sits on top of.
Female Parts
Pistil
This is the female part of the flower. It is made up of the stigma, style, and ovary. Each pistil is constructed of one to many rolled leaflike structures.
Stigma
One of the female parts of the flower. It is the sticky bulb that you see in the center of the flowers, it is the part of the pistil of a flower which receives the pollen grains and on which they germinate.
Style
Another female part of the flower. This is the long stalk that the stigma sits on top of.
Ovary
The part of the plant, usually at the bottom of the flower, that has the seeds inside and turns into the fruit that we eat. The ovary contains ovules.
Ovule
The part of the ovary that becomes the seeds.
Other Important Parts of a Flower
Petal
The colorful, often bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy flowers.
Sepal
The parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens.
Flower Types
Imperfect Flower
A flower that has either all male parts or all female parts, but not both in the same flower. Examples: cucumbers, pumpkin, and melons.
Perfect Flower
A flower that has both the male parts and female parts in the same flower. Examples: roses, lilies, and dandelion.
