(a) Table 1.1 shows three of the processes by which substances in solution can move across cell membranes. It also lists five statements that may apply to each of these three processes. Complete Table 1.1 to show which of the statements apply to each of the three processes shown. Use a tick (✔) to show that the statement applies or a cross (x) to show that the statement does not apply. Each box must contain a tick or a cross. The first row has been completed for you. Table 1.1 statement | process | active transport | facilitated diffusion | simple diffusion movement of oxygen into a red blood cell | X | X | ✔ occurs in both animal and plant cells | | | uses carrier proteins | | | movement of non-polar molecules between the fatty acid tails of the phospholipid molecules | | | movement of ions down a concentration gradient | | | (b) Fig. 1.1 is a simplified diagram representing a transverse section of part of a young root. The diagram is not to scale. [Figure 1.1] (c) Water enters the xylem vessels shown in Fig. 1.1. Explain how water moves up the xylem vessels to the leaves in a continuous column.
