Young plants, also known as seedlings, are the early stages of plant growth that emerge from seeds. They typically consist of a small stem, leaves, and roots. During this stage, young plants rely on stored nutrients from the seed to grow until they can produce their own food through photosynthesis. As they develop, young plants begin to establish their root systems and expand their leaves. This growth is crucial for their survival, as strong roots help absorb water and nutrients from the soil. Proper care, including adequate sunlight, water, and soil quality, is essential for the healthy development of young plants into mature plants.
