Finish Table 1.1 by stating one difference between a bacterial cell and a plant cell for each structural feature shown. The comparison for the cell surface membranes of the two cell types has already been done for you.
One function of the cell surface membrane of bacterial cells and plant cells is moving substances into and out of cells. Explain how membrane carrier proteins and membrane channel proteins are involved in the movement of substances into and out of cells.
Fig. 1.1 is a photomicrograph of chloroplasts in plant leaf cells. Explain why the chloroplasts are visible only around the periphery (edge) of each plant cell.
Fig. 1.2 shows plant cells in a root tip where mitosis is occurring. Identify two cells in Fig. 1.2 that are at different stages of mitosis. Draw a label line to each cell and write the name of the mitosis stage shown by that cell.
