A student has collected samples of cells from the leaves, stem, and roots of a plant and examines each of the samples under a microscope. The student then creates models of the cells from each sample (leaf, stem, root) including labeled structures with accompanying functions. Which of the following correctly identifies and supports how the cell models created by the student might differ from each other? A. The cells of the stem will have a smaller nucleus because they have less genetic material. B. The root cells will have a lysosome because other cells do not have waste. C. Leaf cells will have more chloroplasts because most food is made in the leaves. D. The cells of the stems and roots will have more mitochondria because leaf cells do not need energy.
