小学5年纪向日葵花英文介绍 The sunflower stems are straight, and the leaves are green and bright. What is more lovely is that the sunflower petals are set off by the flower plate. The dark thing in the flower plate is sunflower seeds. Take a few handfuls of them home and fry them. They are fragrant! There is a large sunflower by the lake of my grandmother's house. One day, when I went to fetch a bucket of water and went back to water, I came across sunflowers facing east. At that time, I was in a hurry to go back. When I came back in the afternoon, I found that the sunflowers were facing the West? It turns out that there is a stem between the stem and the disk of the sunflower. There is a plant auxin in this stem. When the sunflower is facing the sun, the auxin is more, and when it is facing the sun, the auxin is less. Therefore, when the sunflower is facing the sun, the sunflower will fall down. Another function is to divide cells, which can make sunflowers grow quickly. I excitedly told everyone this great secret. They all praised me as a little boy who loves observation. I was very proud of myself. After this, I made up my mind to read more books and increase my knowledge. 本文来源：https://www.wddqw.com/doc/dbecc04c32b765ce0508763231126edb6e1a7663.html
