Meet the Parts of a Flower
Open with the idea that flowers are not just pretty; they are plant structures with jobs. Keep the tone warm and curious.
Our learning goal
I can name the main parts of a flower and explain what each part does.

What words come to mind when you think of flowers?
Use this as a friendly starter. Accept both science words and everyday words such as colours, bees, smell, petals, garden, or seeds.
What is a flower?
A flower is the part of a plant that helps it reproduce.
Many flowers have the same main parts, even if they look different in colour, shape, or size.
Use simple examples such as daisies, tulips, or lilies to show that flower shapes vary but key structures are often similar.
The main flower parts
Petals
Sepals
Stamen
Pistil
Ovary
Stem
This slide gives the vocabulary set. Mention that some books may use 'carpel' instead of 'pistil' at a higher level, but keep 'pistil' as the main term here.
A flower is built in layers
Outer layer: sepals
Bright layer: petals
Male part: stamen
Female part: pistil
Base: ovary
Point to the diagram in order from outside to inside so students see the structure, not just a word list.
Different flowers, same jobs
A rose, a lily, and a buttercup do not look the same, but their parts still do similar jobs.
Scientists study these parts to understand how plants grow and make seeds.
Reinforce the science idea of structure and function: shape may vary, function stays linked to the part.
What is the main job of a flower?
Make seeds
Help reproduce
Store water
Make shade
Checks the big idea from slides 2 to 5. 'Make seeds' is tempting, but the deck says the flower helps the plant reproduce.
Complete the flower facts
A flower helps a plant reproduce. Many flowers have the same main parts, even when they look different. The outer layer is made of sepals, and the bright layer is the petals.
Echoes the wording from slides 2 to 4 and checks the key vocabulary set.
Petals
Often bright and colourful
Help attract insects and other pollinators
Can have patterns or scents
Explain that petals are useful, not just decorative. Some flowers rely on colour, smell, or nectar guides to attract pollinators.
Why petals matter
Petals help a flower get noticed.
If pollinators visit the flower, pollen can be moved from one flower to another.
Link petals to pollination without turning this into a full pollination lesson. Keep the focus on the petal's job.
Sepals
Small leaf-like parts under the petals
Protect the flower bud before it opens
Often green, but not always
Students often confuse sepals with leaves. Stress that sepals are attached to the flower and protect the bud.
Before the flower opens
When the flower is still a bud, the sepals wrap around it.
This helps protect the delicate parts inside while they are growing.

Which part protects the flower bud before it opens?
Petals
Anther
Sepals
Style
Targets the common confusion between petals and sepals from slides 6 to 9.
Which clue would help you spot sepals best?
Under petals
Bright colours
Makes pollen
At the top

The stamen
The stamen is the male part of a flower.
It has:
Anther - makes pollen
Filament - holds up the anther
Define pollen simply as a powder that carries male sex cells in flowering plants. Keep wording age-appropriate.
Pollen and the anther
Pollen is made in the anther
The filament lifts the anther up
This makes it easier for pollen to be picked up
You can mention that wind or animals may move pollen, but do not go beyond the key function of the stamen.
Which part of the stamen makes pollen?
Filament
Ovary
Anther
Stigma
Checks understanding of the stamen parts from slides 10 and 11.
Complete the stamen facts
The stamen is the male part of a flower. The anther makes pollen, and the filament holds it up. This helps pollen get picked up.
The final blank is a short load-bearing phrase from the slide text: 'picked up'.
The pistil
The pistil is the female part of a flower.
It includes:
Stigma
Style
Ovary
Keep the exact term 'pistil' throughout for consistency with earlier slides.
How the pistil works
Stigma catches pollen
Style connects the top to the base
Ovary holds the ovules inside
If useful, mention that ovules can develop into seeds after fertilisation, but keep the focus on naming and function.
The ovary at the base
The ovary is at the bottom of the pistil.
It protects the ovules, which may later develop into seeds.
This is a key structure-function link: the ovary encloses and protects developing parts.
Which part catches pollen?
Style
Stigma
Ovule
Stem
Checks the function of the stigma from slides 12 to 14.
Complete the pistil facts
The pistil is the female part of a flower. The stigma catches pollen, the style links the top to the base, and the ovary protects the ovules.
Reinforces the structure of the pistil and the different jobs of each part.
Why is the ovary important?
Expected answer elements: the ovary is at the base of the pistil; it protects ovules; ovules may later become seeds. Encourage short explanations in students' own words.
The stem and support
The stem holds the flower up
It connects the flower to the rest of the plant
Water and nutrients travel through the plant to the flower
You may briefly connect this to transport in plants, but do not expand into xylem and phloem unless the class is ready.
Why support matters
A flower needs support so its petals, stamen, and pistil stay in the right place.
A strong stem helps the flower face light and be reached by pollinators.
This slide helps students see the stem as functional, not just a stick under the flower.
All the parts work together
Sepals protect the bud, petals attract pollinators, the stamen makes pollen, and the pistil receives it.
Each part has a special job, and together they help the plant reproduce.
This is the lesson landing point. Reconnect to the central idea that a flower is a structure with coordinated functions.
Why does the stem matter to a flower?
It makes scent
It catches pollen
It gives support
It makes seeds
Checks the stem's support job from slides 15 to 17.
Complete the summary
The stem holds the flower up and connects it to the plant. Petals attract pollinators, the stamen makes pollen, and the pistil receives it.
This summary links support and reproduction in one short review.
