When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though. <sep>What do humans have that plants don't have?<sep>Immune systems
Yes

The judge leaned back in his chair and beckoned to Mr. Andrews. It was finished. Spear was free, and from different parts of the courtroom people were moving toward the door. Their numbers showed that the friends of the young man had been many. Mr. Thorndike felt a certain twinge of disappointment. Even though the result relieved and pleased him, he wished, in bringing it about, he had had some part. He begrudged to Isaacs & Sons the credit of having given Spear his liberty. His morning had been wasted. He had neglected his own interests, and in no way assisted those of Spear. He was moving out of the railed enclosure when Andrews called him by name. "His honor," he said impressively, "wishes to speak to you." The judge leaned over his desk and shook Mr. Thorndike by the hand. Then he made a speech. The speech was about public-spirited citizens who, to the neglect of their own interests, came to assist the ends of justice, and fellow-creatures in misfortune. He purposely spoke in a loud voice, and every one stopped to listen. "The law, Mr. Thorndike, is not vindictive," he said. "It wishes only to be just. Nor can it be swayed by wealth or political or social influences. But when there is good in a man, I, personally, want to know it, and when gentlemen like yourself, of your standing in this city, come here to speak a good word for a man, we would stultify the purpose of justice if we did not listen. I thank you for coming, and I wish more of our citizens were as unselfish and public-spirited." It was all quite absurd and most embarrassing, but inwardly Mr. Thorndike glowed with pleasure. It was a long time since any one had had the audacity to tell him he had done well. <sep>Who did Mr. Thorndike want to help?<sep>Himself
No

Greta ran to the corner with her older brother Tony. He had money for the ice cream truck in his pocket and she was very happy. The ice cream truck had been parked at the curb waiting for children for a very long time. The ice cream truck driver thought that no more children were coming to get ice cream so he started pulling away from the curb when they got to the corner. They yelled. They screamed, "Stop! Stop!" and jumped up and down on the side walk trying to get him to see them. The driver of the truck saw them, waved at them and smiled, pulled back to the curb and opened his truck up so that they could see everything that he had for sale. They were so excited. They saw some new treats. Tony wanted to try something new. He got an ice cream sundae with chocolate ice cream and nuts. He almost got a snow cone. Greta looked at everything that the ice cream truck had. She saw candy, ice cream cones, snow cones, and everything else. It all looked so good. But after looking at everything, she wanted to get an ice cream sandwich. She got the ice cream sandwich. She bit into it and smiled. It tasted so good. She felt so happy. Her brother, Tony, was happy too. He bit into his ice cream cone sundae and grinned. They walked home with their ice cream and told their mom about how close they came to not getting their ice cream at all. Their mom was happy that the truck had stopped for them. She said that they were very lucky to have gotten to the curb before the ice cream truck left. <sep>What treats did Greta and Tony buy from the ice cream truck?<sep>Candy
