Wheat seedlings are the young plants of wheat that are characterized by their green color, which is typical of most plants in their early growth stages. The green color in plants is due to the presence of chlorophyll, a pigment essential for photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth. As the seedlings grow, they develop a robust root system and begin to produce leaves, which are green due to the chlorophyll they contain.
