Bees are attracted by the flower's colour and sweet-smelling nectar. As they sip the nectar, they may brush pollen on to the stigma or take some on their bodies to the stigma of other flowers. Pollen is so tiny you can see it only under a microscope. This is yew pollen. Fruits and seeds A hazelnut is a fruit with a hard case holding a single fruit.
Fruits come in many shapes and sizes.
Some, such as oranges, bananas and tomatoes, are soft and juicy. The hard pips are the seeds. Others, such as acorns and hazelnuts, have a hard, dry shell. Peas, beans and other legumes are soft, dry fruits held in a case called a pod. Apples and pears are false fruits because they include other parts.
