Looking at flowers
It’s hard to imagine a world without flowers. Plants that have flowers grow almost everywhere, from gardens to high mountains. Every flower has a particular shape and color, so that it can perform a special job. By the time you’ve finished reading this book, you’ll know what this job is, and how the flower does it. Always ask permission before picking a flower.
Animal visitors Many flowers have lots of animal visitors throughout the day, or sometimes even at night. But what are these animals doing? Read on, and you’ll find out.
There is much more to a flower than just its petals. Later on, you can discover what else makes up a flower, and what all the different parts do.
Flowers in close-up A good way to find out about flowers is to take one apart. The petals are often big and bright. If you take the petals off, however, you will be left with the important parts of a flower—the ones that make the seeds.
Simple flowers Kingcups and poppies are called simple flowers. Their petals are arranged in a circle. In the center of the flower are the parts that produce the seeds.
Complicated flowers If you look at flowers in a garden or in the countryside, you will see that they come in many shapes. Some flowers are flat and round. Others are shaped like funnels, beaks, or even umbrellas.
These types of flowers are called complicated flowers. How many petals? An everlasting pea has five petals. Two are joined together making the inside of the “beak,” which sticks forward. Two more lie on either side, while the fifth makes a curved “hood” around the top of the flower.
Flowers with a difference In nature, things are not always what they seem. Some plants have small, drab flowers, but they still manage to put on a brilliant show of color. Instead of petals, they use brightly colored leaves, or sepals, to attract insects.
Two in one Take a look at this “lacecap” hydrangea flower head. It is made up of many tightly packed flowers. Some of the flowers have big, colorful sepals, while the others are very small.
