Summer Flowers The world is full of flowers. They grow on every continent. They grow in the driest deserts and in the frozen Arctic. People grow them year-round. No matter hottest where you live, you can usually see a flower somewhere

WHAT’S A FLOWER FOR? What exactly is a flower? What’s it for?

Plants make flowers because flowers make seeds. Seeds are a way many plants reproduce, or make new plants. So, flowers help plants reproduce themselves.

Flowers also make fruit as part of the reproduction process. Once the seeds start to ripen, a part of the flower grows around them. This is what fruit is. Fruit feeds, protects, and helps to spread a plant’s seeds.

So, the next time you eat an apple or pear or peach, think about this: what you’re eating came from a flower. In fact, without flowers, there would be no fruit at all!

ALL SHAPES AND SIZES Flowers come in all shapes and sizes. Some are so small you can barely see them. A type of duckweed called Wolfed makes a flower so small that a dozen blooms could fit on the head of a pin. Other

PROJECT flowers are enormous. A flower in Southeast Asia called Raffles can grow to 3 feet (about 1 meter) wide.

WHEN DO PLANTS MAKE FLOWERS? Some plants make flowers year after year. Others only bloom every two years. And some flowering plants live only one season. New ones must grow from seeds every year.

Most flowers wait for a certain time of year or certain conditions to bloom. The morning glory opens with the sunrise. Yucca flowers open at sunset. The night-blooming cereus opens only at night.

Sometimes a bare desert can burst suddenly into colorful flowers after a single big rain. The flowers wait for just the right conditions and then bloom quickly.

HOW DO FLOWERS MAKE SEEDS? Seeds only develop after they are fertilized by pollen.

So to make seeds, flowers must first make a powdery substance called pollen. The pollen then has to be carried from one flower to another flower of the same type, or sometimes to a different part of the same flower. Once this happens, the seeds are fertilized. They can then begin to mature.

For flowers to move the pollen, they need help. In many plants, wind or water spreads the pollen. But most of the help comes from insects such as bees and butterflies, or other animals such as bats. These creatures all feed on flowers. When they do, they move the pollen.

Maybe you’ve seen a honey bee working in a flower? The bee is collecting pollen or maybe the flower’s sweet nectar. Bees use pollen to feed young bees. They use nectar to make honey. While the bee works, pollen sticks to its body. When the bee moves to a new flower, some of the pollen falls off on the new flower.

HOW PEOPLE USE FLOWERS

PROJECT People prize flowers for their beauty. We paint pictures of them and use them for decorations. We give them as signs of friendship, love, or remembrance. Some flowers are important in religious ceremonies.

Others are considered sacred by some groups.

Flowers have many practical uses. Lavender is a flower used to make perfume. Witch hazel is used in cosmetics. A flower called the rosy periwinkle is used to make medicine to fight leukemia, a blood disease.

Like other animals, people even eat some kinds of flowers! You probably have. Broccoli and cauliflower are flowers that haven’t quite opened yet. Some people add flower petals to salads. Roses are used to make tea or jelly. Dandelions can be used to make wine.

But you don’t have to use flowers to enjoy them. Flowers sometimes nice just for their shape and color or for their Sweet smell.

It grows best in sunny locations with fertile, Well-drained soils.

PROJECT Asters include about 250 species of perennial flowering plants distributed widely around the world. Many species are cultivated for their bright and varied colors. .

Rosy Periwinkles The rosy periwinkle, found in Madagascar, contains dozens of alkaloids, two of which are used to treat childhood leukemia and Hodgkin’s disease.

SUNFLOWER Sunflower, common name for annual and perennial herbs of a genus of the family of composite flowers.

The genus, which contains about 67 species, is thought to be native to South America originally, although sunflowers are now Stributedi almost worldwide. Some of the tall-growing forms may attain a height of 3 m (12 ft). The large, solitary blossom, sometimes as large as a meter in diameter, is composed of yellow ray flowers and a central disk of either yellow, brown, or purple flowers, depending on the species. The daily orientation of the flower to the sun is a direct result of differential growth of the stem. A plantgrowth regulator, or axing, accumulates on the shaded side of a plant when conditions of unequal light prevail. Because of this accumulation, the darker side grows faster than the sunlit side. Thus, the stem bends toward the sun.

The plants are cultivated for their seeds. Refined sunflower-seed oil is edible and considered by many equal in quality to olive oil. Cruder sunflower oil is used for making soap and candles. The oil cakes (solid residues after oil is expressed) are used as cattle feed. The raw seeds are used in poultry mixes and are consumed by humans as well. The roots of one species, also called Jerusalem artichoke ( see Artichoke, Jerusalem), may be eaten boiled, stewed, or baked in pies.

Water lilies grow in freshwater they often float on the surface of ponds or lakes Butterflies visit flowers to feed on nectar. As butterfly feeds a power on the flower called pollen sticks to the insect’s body. The butterfly spread the pollen to other flower it visits, allowing the plants to reproduce.

Plants come in many shapes and sizes. Most have some basic structure, including underground roots, A stem for support, and leaves that that use light , water , & carbon dioxide ( A gas in the air ) to make food .
