Photosynthesis sustains plant growth, and inputs of sunlight sustain photosynthesis. Why, then, do seedlings that germinate in a fully darkened room grow taller than seedlings or the same species that germinate in full sun?
To explain: Why do seedlings that germinate in a fully darkened room grow taller than seedlings of the same species that germinate in full sun.
Concept introduction: Every living creature is programmed to survive in its own environment. Still, they require many essential factors necessary for their growth and development. If there is any scarcity for what they need, they get easily adapted with the existing conditions and continue to grow. For plants, there are several important factors essential for their growth and development starting from their seedling stage to death. Sun light, water, and fertility of soil are some of their fundamental requirements.
