C

A blow-fly was looking for an ideal place like rotting meat to lay her eggs so that when her little babies were born, they could feed on the meat.

As she turned a corner in the grassland, she smelt something that smells like rotten meat in the air! With a great joy she landed on it and laid her eggs. She was happy that her children would have enough food to eat.

But the fly did not know she had made a great mistake. What she had sat upon was not meat but a flower, which smells badly. It is called a carrion flower. So, when the blow-fly’s eggs hatched and the little maggots(蛆)came out, they had nothing to eat. They died of starvation.

The carrion flower is one of the many flowers which send out dirty smells to attract flies. The Rafflesia stinks like rotting meat, while the tropical Lords and Ladies flower gives out a smell like rotting fish.

They do it for a special reason. These plants cannot move from their place. But it is important for the male cell of one plant to get in touch with the female cell of another plant. Once that is done, the seed of the plant will bloom and give birth to another plant.

The plant uses its stink to attract flies. As soon as the blow-fly sits on the follower, it is captured by the flower with strong hair. When the hair falls, the fly is free to fly- but it takes some pollen(花粉) with it. And goes and sits on another plant. The male cell of one plant meets the female cell of the other. The seed gets new life.
