Flowering Plants – Background Information;
The different parts of flowers are specialized to help plants reproduce as efficiently as possible. There is a
female part of the flower, and a male part of the flower. The female part of the flower is in the center and is
made up of the ovary, the style, and the stigma. The stigma is sticky and captures the pollen from other flowers
(sometimes carried on the legs and abdomen of pollinators such as bees, butterflies, hummingbirds etc.). The
pollen germinates on the stigma and travels down the inside of the style, toward the ovary. Once the pollen
reaches the ovary, it combines with the female gamete to make a seed, or ovule. The male part of the flower is
the anther, stamen and filament. The anther carries the pollen, which fertilizes the female parts of the flower.
The stamen and the filament hold up the anther. The petals are the colorful structures that help the flower to
attract pollinators. Sepals are like petals, usually attaching below the petals on the receptacle. The receptacle
is the part of the flower that is left once the flower has been fertilized, and the petals fall off. This part of the
flower swells as the seeds develop. The peduncle is the junction between the receptacle and the stem of the
In this lesson, students explore the reproductive functions of flowers by participating in a flower
dissection lab. Students will then apply their knowledge to flowering plants at their surroundings.
Anther – Forms pollen grains.
Filament – Supports the anther.
Ovule – Found inside the ovary and after fertilization develop into seeds.
Ovary – The lower, often times enlarged part of the pistil, which contains the egg cells and produces the seeds.
The ovary becomes the fruit.
Petals – Leaf-like, often colorful part of the plant that surrounds the reproductive parts of the flower and makes
the flower conspicuous to pollinators. Petals collectively form the corolla.
Pistil – The female part of the flower, which is comprised of three parts stigma, style, and ovary.
Pollen – Fine powder dust that contains the sperm from a male plant.
Pollination – Transfer of pollen from the anther of a stamen to the ovule of a flower.
Sepals – Green leaf-like structures that protect the flower bud. Collectively sepals are referred to as the calyx.
Sometimes sepals are colorful like the petals.
Stamens – The male parts of the flower that produces pollen grains. Stamens consist of a filament and an
Ovary – The lower, often times enlarged part of the pistil, which contains the egg cells and produces the seeds.
The ovary becomes the fruit.
Stigma – Where pollen grains land on the pistil.
Style – Connects the stigma and ovary. Pollen grains travel to the ovary via the style

By the end of lesson student will able to,
Identify the different parts of a flower and understand their functions in pollination.
Understand the importance of pollen for plant reproduction and diversity.
Dissect a flower, working from the outermost whorl to the innermost whorl.
Create and label a cross-section diagram of the dissected flower, including an explanation of how each
part of the flower labeled affects flower reproduction.
5. Students will be able to distinguish flowers and their pollinators in the field.
With a partner, have students brainstorm a list of all the flower parts they know. Have them share with the
class and make a classroom list of parts shared. Tell students that they are going to learn flower parts and their
function. Show students a diagram of a flower and discuss the locations of the parts of the plants and their
functions. The following parts should be included in this discussion: pistil, stigma, ovary, ovule, stamen, anther,
petal, and sepal. Students can be given this information and be asked to research, draw, or label a blank
flower diagram for further understanding.
Once students are familiar with the different flower parts, have each student, or student pair, select a flower to
study. Ask students to observe the flower with their eyes and with a magnifying glass only. Make sure each
student should note down on their copy.
Have students, with a partner, brainstorm ways that plants are pollinated. When they have finished discussing,
have them share their ideas with the class. Discuss, using student ideas as a guide, how the structure of plants
contribute to pollination.
Students should be able to,
Label a diagram showing the parts of a flower.
Observe and describe their flowers using appropriate language.
Develop their own hypothesis on how pollination occur based on observations.
Compare and contrast the structure and function of the flower parts studied. Know what is similar in
each flower? What varied? What functions do they have in common?
5. Explain different ways flowers can be pollinated. What flowers would be best pollinated by a bee?
Which would be best pollinated by the wind? Is one method of flower pollination more common among
the flowers studied than another? Why?
6. Discuss the benefits of animal pollination for both flowers and their animal pollinators.
Group Work
Teacher will divide students into FIVE-FIVE group by changing their seating position and also by merging top,
average and low grade students
Teacher provide reading task to student to develop question and write their answer.
Student develop question and answer on the note book and share the task in group.
Teacher give feedback after listening and checking their task
Home task;
❖ Read the topic cell again and make 10 questions with their answer.
❖ Student writes down the question with their answer.
❖ Student draws the proper diagram of plant reproductive system
