🌸 Plants with Flowers
Many plants have flowers. They are called flowering plants. There are many different kinds of flowers. Some flowers are big, and some are small. Some are colourful, while others are not brightly coloured. Some flowers have a smell — a scent. Others do not have a scent.
🌱 Plant Life Cycles
All flowers do the same important job. When a plant produces flowers, the flowers usually last only a few days. Then they die and fall off the plant. However, part of the flower stays behind on the plant. This part becomes the fruit. The seeds form inside the fruit. The seeds grow into new plants. The new plants grow and produce flowers to form new fruits and seeds.
So flowers help the plant reproduce to form new plants.
All the changes in a flowering plant—from flowers to seeds growing into new plants—are called the plant’s life cycle. A cycle is something that happens over and over again. There are different stages in the life cycle of a flowering plant.
🌿 Plants Without Flowers
Not all plants have flowers. Plants without flowers are called non-flowering plants. Mosses, ferns, and plants with cones are non-flowering plants.
Some non-flowering plants, such as ferns and mosses, do not form seeds. Instead, they make tiny spores that can grow into new plants. Other non-flowering plants, such as pine trees, do form seeds — but their seeds grow inside cones rather than flowers.

🌸 The Parts of a Flower
Flowers have four main parts. These parts are arranged in rings, one inside the other. The petals are often brightly coloured to attract insects to the flower. The stigma is sticky to catch pollen. The anther makes a powder called pollen, which is held up by a stalk called the filament.
The ovary contains tiny eggs, while the sepals are small green leaves that protect the flower bud. The carpel is the female part of the flower and contains the ovary.
🌼 Male and Female Parts
Most flowering plants have flowers that contain both male and female parts. However, some plants have flowers with only male parts or only female parts, not both. The male parts make pollen, and the female parts receive it to form seeds.
🧠 Think Like a Scientist 2: Observe and Draw a Flower
🔍 Investigation: Observe and draw a flower to learn about its parts and their functions.
🧰 You will need: A flower, hand lens, tweezers
🛡️ Safety First:
- Wash your hands carefully after touching the flower. 🧼🌸
- Handle tweezers gently and avoid damaging the flower. 🌿
📝 What to Do:
- Draw the flower and label its parts. ✏️🌺
- Count and record the number of petals, sepals, and stamens. Write your results in a table. 📊
- Carefully remove the petals and sepals using the tweezers. 🪡
- Use the hand lens to look closely at the stamens and the carpel. 🔍
- Find the anthers. Touch them gently — what do you notice on your fingers? 🤔
- Find the stigma and touch the tip. How does it feel? 👆
❓ Questions:
- Petals
- Anthers
- Stigma
- Ovary
(You may need to look for the answer in a book or online!) 📚💻
👀 Show answer
- 1a: Petals attract insects with their colour and scent. 🌸
- 1b: Anthers make pollen for fertilisation. 🌾
- 1c: The stigma catches pollen. 🌼
- 1d: The ovary contains eggs that develop into seeds. 🌱
- 2: The petals or special scent glands make the flower’s fragrance. 🌹
- 3: Some flowers mimic the smell of rotting meat to attract flies for pollination. 🪰🌺
