From what do most plants begin growing?

Most plants begin growing from seeds because seeds contain all the necessary materials to develop into a new plant. When seeds are planted in the right conditions—such as adequate moisture, sunlight, and soil—they start the germination process. During germination, the embryo inside the seed begins to grow, using stored nutrients until it can develop its own leaves to start photosynthesis. This process allows the seed to sprout and establish roots and stems, ultimately leading to the formation of a fully grown plant. The other choices represent different parts of a mature plant, but seeds are the initial starting point for new growth.
