Flower – Structure and Function

Subject
Natural Science · 6th Grade
Duration
45–65 minutes
Materials
Corinth 2.0, flowers (tulip / gerbera), text, worksheet, VR
Lesson Objective
Students will draw and describe the structure of a flower, and compare flowers of different plants.
1
Lesson Introduction and Leaf Review
  • Greeting, attendance, presentation of lesson objectives.
  • Brief review of leaf material:
    • What is the most important function of a leaf?
    • What is the tissue that allows the stem to grow in width called? (cambium)
    • Identify the type of root in a carrot (main – storage).
  • Connecting to parts of root, stem, and leaf – today we focus on the flower.
2
What Do We Already Know About Flowers?
  • Where can we find a flower?
  • Why aren’t all flowers the same?
  • What is the function of a flower?

Functions of a flower:

  • sexual reproduction of the plant,
  • attracting pollinators (colors, scent),
  • carries both floral envelopes and reproductive organs.
3
Explore the Flower in 3D

Using the 3D strawberry flower model, students examine individual flower parts and review their functions.

If the model does not load, open it in a new window:
app.corinth3d.com/content/p_rost_jahodnik_kvet

Find in the model:

  • stamens – anther and filament;
  • pistil – stigma, style, ovary;
  • petals and sepals;
  • receptacle.
4
Flower Structure

Distribute text + flower image to groups. The task is to label each part.

  • Pistil – stigma, style, ovary
  • Stamen – anther, filament
  • petals, sepals
  • receptacle

After group work, review the correct answers together (e.g., according to presentation or textbook).

Comparison of real flowers:

  • Tulip × gerbera – students identify differences using the Corinth app and real flowers.
5
Reproductive Organs and Flower Types

Female reproductive organ: pistil (stigma, style, ovary).

Male reproductive organ: stamens (anther, filament).

According to the presence of reproductive organs, flowers are classified as:

  • Unisexual – contain only stamens or only pistils.
  • Monoecious – male and female flowers on the same plant (e.g., corn).
  • Dioecious – male and female flowers on different plants.
  • Bisexual – flower has both pistil and stamens (e.g., tulip).
6
Individual or Group Work

Choose 1 task:

  • Draw a flower from the 3D model and label its parts.
  • Create a short video or presentation about flower structure.
  • Write a story: "I am a flower waiting for a bee…".
  • Find differences between monocot and dicot flowers (you can use VR or additional models in the app).
7
Evaluation and Conclusion
  • What did you like today? What was new?
  • Did the Corinth app help you see the flower up close?
  • Is it easier to study a flower in 3D or in the textbook?
  • Final farewell.
