Flowers come in many different shapes , sizes and colours However , most have the same structure. Most flowers have male parts, called stamens , and female parts, called carpels. The stamens produce fine , dustlike grains , called pollen , and carpels produce ovules. The male and female parts are surrounded by petals of the flower. In many flowers , it is the job of the petals
to attract insects , so that pollen can be transferred to other flowers. This process is called pollination. The pollen then joins together with , or fertilizes , the ovules , and produce seeds.
