The contents of Hua's handwritten newspaper are as follows:

1. Flowers are deformed short-branched ornamental plants with reproductive function, and there are many kinds.

2. Typical flowers are calyx, petal, stamen and pistil, which produce germ cells on the short axis and their growth is limited. Flowers consist of corolla, calyx, receptacle and stamens. They have all kinds of colors, some of which are gorgeous and fragrant.

3. Some scholars think that gymnosperms are flowers, while most people think that angiosperms have real flowers, so angiosperms are also called flowering plants.

4. The part of the flower is not easily influenced by the external environment. For a long time, the morphological structure of flowers has been regarded as the main basis for the classification, identification and systematic evolution of angiosperms.

Many plants will produce bright and fragrant flowers.

6. These flowers are the sexual reproductive organs of plant seeds, which can reproduce offspring for plants. Flowers attract insects with their colors and smells to spread pollen.

7. Poppies grow very fast, bloom and die within one year, and are called annuals. A poppy can form hundreds of seeds. But not all plants are like this. More plants can live for years. This plant is called a perennial.

8. A bud is a small suitcase full of things. It is covered with a hard skin, which can prevent it from being hurt. Inside, different parts of the flowers are tightly wrapped, so they only take up a small space.

9. When the bud grows, the flowers spread out inside.

10, plants produce seeds after the combination of two pollen sacs.

1 1, a pollen sac called ovule, which is formed at the bottom of the flower and protected by the ovary; Another kind of pollen sac is called pollen grains. Pollen grains need to combine with ovules of other flowers, so pollen must be transferred from one flower to another.

12. When you see insects flying among flowers, it's that they are spreading pollen.

13. When the bee comes to the flower, it will get pollen.

14. When it flies to another flower, it will spread some pollen and then get more pollen. The reward of bee's hard work is that it can get sugary nectar as salary.

15. In summer, the air contains a lot of pollen. Some people sneeze after breathing this air because they are allergic to pollen.
