Quizplus · Accepted Answer

During the first week, before the seedling emerged from the soil, the plant would have used starch from the seed as a source of energy for growth. This is because the initial energy reserves for the plant are stored in the seed as starch. As the plant develops and its leaves start to function, it starts using light energy for photosynthesis to produce its own sugars. So, options A, B, D, and E are not correct in this context.
