Answer
(c) Complete the sentences.Water moves into and out of cells by a process called **osmosis**.Water would move **out of** the potato cells in tube **A**.The solution outside the potato in tube **A** is at a **higher** concentration than the solution inside the potato cells.(d) The potato in tube **B** did not change.Give one conclusion that can be made from this observation.The solution inside and outside the potato cells in tube **B** are at **equilibrium** (or the solution is **isotonic**).
Explanation
## Step 1:The process by which water moves into and out of cells is called osmosis. Osmosis is the diffusion of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.## Step 2:To determine the direction of water movement in tube A, we need to compare the solute concentrations inside and outside the potato cells. If the solution outside the potato cells in tube A is at a higher concentration than the solution inside the potato cells, water would move out of the potato cells. This is because water moves from an area of lower solute concentration (inside the potato cells) to an area of higher solute concentration (outside the potato cells).## Step 3:If the potato in tube B did not change, it means that the solute concentrations inside and outside the potato cells in tube B are equal. This is an isotonic condition, where there is no net movement of water because the concentrations are balanced.
