Plants convert energy into nutrients for their seeds through photosynthesis, allowing the seeds to grow and develop in a suitable environment. They would usually choose a suitable location deep underground and spread the seeds directly into the surrounding soil through their roots. Sometimes, plants would also use other methods to spread their seeds. For example, some plants would secrete substances on their stems or leaves to adhere their seeds to these substances. As the plant grew, these substances would spread down and spread the seeds into the surrounding soil. There were also some plants that used wind, water, and animal methods to spread their seeds. For example, some sunflowers relied on wind to spread their seeds into the surrounding air, while some cacti used water to spread their seeds near water sources. Plants spread their seeds in a variety of ways, each with its own advantages and disadvantages, as well as its scope of application to adapt to different environments and scenarios.
