One morning, I saw my mother watering the flowers and asked her, "Mom, if you water them, the flowers will grow.". Why? " "Son, this is because the roots of plants are conveying nutrients to flowers!" However, after listening to my mother, I still don't quite understand. When my mother saw that I still didn't understand, she said to me, "Never mind, how about I give you a little experiment?" When I heard that I was going to do the experiment, I danced with joy and shouted, "Good! You did a good job. I like doing experiments best! " We have prepared blue ink, plasticine, a plant with white flowers, dropper, marker, cup and water. My mother said to me, "Be careful not to break the cup!" " ""sure! "I promise that the experiment has begun. My mother put the water in the cup first, and then I sucked the red ink out with a dropper and dropped it into the cup filled with water. Then, my mother dipped the plant with white flowers and roots into the water. Suddenly, the bottom of the root began to turn red. I sealed the cup with plasticine, and my mother finally marked it with a marker. It was Ok! Mom added: "Remember to observe again in a week." "Yes!" I cried. I am really looking forward to it! Even dreamed about the story of this experiment. Time flies, a week has passed quickly, and today, the truth comes out! I'm so happy. As soon as I arrived at the experimental cup, I saw that the flowers turned red and there was less water in the cup. The last step is to cut the stem, so mother carefully cut off the stem of the plant with a knife. Wow! The stem suddenly turned red, and so did the root! It's amazing! Mother said: "The reason why flowers turn red is because the stems of plants transport water and nutrients, and the roots of plants absorb water and nutrients. "It is this sentence that makes me understand that those flowers will grow, which is the role of stems and roots, and also the role of water. Now I fully understand. Do you know the man sitting here?
