Parts of a flower

What this diagram shows

Flowers are how flowering plants reproduce. This half-flower diagram shows the outer parts (petals and sepals), the male part, called the stamen (an anther on a filament), and the female part, called the pistil (a stigma, a style and an ovary). The purple brackets mark the whole stamen and the whole pistil, so they can be tapped as well as their smaller parts. Explore, Labels and Quiz me work as on our other diagrams.

The pollination steps add a bee. It arrives carrying pollen from another flower, leaves some on the sticky stigma, gets dusted with new pollen from the anthers and flies off. Then a pollen tube grows down the style, fertilization happens in the ovary, and the ovules become seeds as the ovary swells into a fruit.

Why the story helps

Students can label a flower and still not know why the parts are arranged as they are. Watching the bee move pollen from anther to stigma shows the purpose of each part: bright petals to attract, anthers where insects brush against them, a sticky stigma to catch pollen. A Think first question before every step keeps the student predicting rather than just watching.

Common misconceptions

• Pollination and fertilization are not the same thing. Pollination is pollen landing on a stigma; fertilization happens later, when a male cell from the pollen joins an ovule.
• Bees do not visit flowers to help them. They come for nectar and pollen as food, and pollination happens along the way.
• Not all flowers need insects. Grasses and many trees are pollinated by wind, and some flowers pollinate themselves.
• Fruits are not only sweet things. In science a fruit is a ripened ovary holding seeds, so bean pods and tomatoes are fruits too.

A 10-minute flower activity

• If possible, look at a real flower such as a lily or a tulip, which have large, easy-to-see parts.
• In Explore, tap each part and find it on the real flower.
• Step through pollination, pausing at each Think first question.
• Ask the student to retell the story in their own words, using anther, stigma, style, ovary and seed.
• Finish with Quiz me.

Where this fits in school

• US, grade 2: NGSS 2-LS2-2 asks students to model how animals pollinate plants or spread seeds.
• US, grade 4: NGSS 4-LS1-1 covers plant structures that support growth and reproduction.
• US, grades 6 to 8: NGSS MS-LS1-4 asks how specialized plant structures, such as bright petals and nectar, make successful reproduction more likely.
• England, Year 3: pupils identify the parts of flowering plants and explore pollination, seed formation and seed dispersal. At Key Stage 3, they study flower structure, wind and insect pollination, and fertilization.
