1、 Sprout
Trees grow through seeds, which can be sown or dropped into the soil with the help of wind. Most of them begin to germinate in spring. Radicle, germ and hypocotyl grow from the seeds, and then continue to grow. The germ develops into the outer part, emerges from the soil, and then seedlings grow p>
2、 Development
The outer leaves will continue to absorb sunlight, which can carry out photosynthesis and begin to form glucose, which is the nutrient for growth. These nutrients will be continuously transported to all parts of the plant. In the process of continuously forming nutrients, it can promote its subsequent growth and development. In addition, roots also absorb water and various nutrients from the soil, and then transport them to various parts through ducts to promote their synthesis of nutrients p>
3、 Heighten
Through synthetic nutrition year by year, cells divide many times, and then absorb water to grow. Trees will grow taller and thicker, mainly due to the role of cell cambium p>
4、 Blossom and bear fruit
For some plants that can blossom and bear fruit, when they grow to a certain stage, the trees will bloom and bear fruit normally according to the changes of seasons p>
