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).

Activity Card 1Parts of a Flower

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.

Reference CardWhat you need to know………

The Basic Flower PartsThe flower consists of many different parts. Some of the most important parts being separated into both male and female parts.Male PartsStamenThis 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.AntherThis 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.FilamentThis is the fine hair-like stalk that the anther sits on top of.

Female PartsPistilThis 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.StigmaOne 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.StyleAnother female part of the flower. This is the long stalk that the stigma sits on top of.OvaryThe 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.OvuleThe part of the ovary that becomes the seeds.Other Important Parts of a FlowerPetalThe colorful, often bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy flowers.SepalThe parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens.Flower TypesImperfect FlowerA flower that has either all male parts or all female parts, but not both in the same flower. Examples: cucumbers, pumpkin, and melons.Perfect FlowerA flower that has both the male parts and female parts in the same flower. Examples: roses, lilies, and dandelion.
