Flowers are not just pretty to look at. They do important jobs for the plant. Today, we will learn what these jobs are. We will find out together!
1. Pollination: How Flowers Make New Plants
Pollination is a big word, but its job is simple. It helps plants make seeds. These seeds grow into new plants. Flowers are a big part of this cycle. Let us explore how!
- Bees and Butterflies: They visit flowers for nectar. They touch the pollen. Pollen sticks to them. Then, they carry it to other flowers.
- Wind and Water: Sometimes, wind blows pollen from one flower to another. Water can also carry pollen to other flowers.
- Why is Pollen Important?: Pollen has plant ‘dust’ that helps make seeds. When pollen moves from one flower to another, it can create a seed.
Pollination is like a flower’s way of talking. It shares parts of itself with others to grow new life.

2. Attraction: The Beauty Contest
Flowers are beautiful. They have bright colors for a reason. They want to attract friends like bees and birds. Let’s find out how flowers use their beauty:
- Bright Colors: Flowers wear colors like a dress. This helps them stand out. Insects and birds see these colors and want to visit.
- Sweet Scents: Flowers smell good. This scent calls to their insect friends. It’s like saying, “Hey, come over here!”
- Nectar: This sweet liquid is a treat for visitors. Insects love it. It’s like a reward for their help with pollination.
Attraction is the flower’s way of making friends. It uses colors and scents to say hello.
3. Reproduction: Creating New Flowers
Reproduction is how a flower makes baby plants. It uses seeds. These seeds need to be made first. Let’s learn how a flower does this:
- The Stamen: This is the boy part of the flower. It holds the pollen.
- The Pistil: This is the girl part of the flower. It catches the pollen.
When pollen from the stamen reaches the pistil, magic happens. A seed can start to grow! Then, a new plant can begin its life.
| Part of Flower | Its Job |
|---|---|
| Petals | Attract friends with their colors |
| Nectar | Give sweet rewards to visitors |
| Stamen | Hold pollen, the boy part |
| Pistil | Catch pollen, the girl part |

4. Seed Protection and Dispersal
Once seeds are made, they need to be safe. The flower changes to protect its seeds. It can also spread its seeds. Let’s check out how:
- Fruit: Some flowers make fruit. The seeds are inside. When animals eat the fruit, seeds travel to new places.
- Seed Pods: Some flowers make pods. When the time is right, these pods open. Seeds fly out and land in new homes.
Seed protection and travel are key. It helps flowers grow in new places. It gives them more space to live and grow.
5. Food Source
Besides making new plants, flowers feed others. They are a food source. This helps the whole garden. Let us see how flowers feed friends:
- Nectar: Insects drink nectar. It gives them energy to fly and work.
- Pollen: Some insects eat pollen. It is full of good stuff.
- Flower Parts: After pollination, some parts wilt. Others eat these parts.
Flowers are like tiny kitchens. They offer food to many creatures. This keeps the garden alive and happy.
Frequently Asked Questions For What Are The Main Functions Of A Flower Class 6: Unveiled Secrets!

What Is The Purpose Of Nectar?
Nectar functions as a reward for pollinators, providing them with a rich energy source to encourage the transfer of pollen.
How Do Flowers Contribute To Seed Dispersal?
Flowers develop into fruits that encase seeds, enticing animals to facilitate seed dispersal when they eat the fruit and excrete the seeds elsewhere.
Can Flowers Regulate Their Temperature?
Some flowers can regulate their temperature, using metabolic heat to attract pollinators by increasing the volatilization of attractive scents.
Why Do Some Flowers Open At Night?
Flowers that open at night typically adapt to attract nocturnal pollinators, such as bats and moths, by releasing strong fragrances.
How Do Stamens Function In A Flower?
Stamens are the male reproductive parts of a flower, producing pollen which contains the sperm needed for fertilizing ovules.
What Role Does The Ovary Play In Flowers?
