The correct answer is option C. A leaf growing in full sunlight
The chloroplast is an organelle, which helps the plants to carry out the process of the photosynthesis. The leaves are the main site of the photosynthesis in the plants, hence, they have an abundant number of chloroplasts present in the cells. In the presence of the sunlight, they perform the light dependent reactions of the photosynthesis process. In case, a scientist find out the cell, which have a high number of chloroplast, then the cell must be specialised to perform photosynthesis, hence, the cell would belong to the leaves, which are growing in full sunlight.

D. All of these could be explained by the blending idea
<span>The units of a pyramid of energy </span>are expressed in units of energy per area per time (e.g. kJ
m^–2 year^–1) which is grams per meter2<span> per year or calories per meter</span>2<span> per year</span><span> so letter A will be the
answer.</span>
