Answer 1

Hypertonic solutions cause **plasmolysis** (shrinking of cell due to osmosis). The central vacuole loses water, the cell membrane shrinks and pulls away from the cell wall.When plant cells are placed in a hypotonic solution, they admit water. As water enters, pressure builds up inside the cell (**turgor** pressure). When **turgor** pressure equals osmotic pressure, the plant is said to have developed **full turgor**.Carrier-mediated transport utilizes **protein carriers** in the cell membrane to control the passage of molecules in and out of the cell.1) These carriers are **specific** - each carrier passes only one type of molecule.2) This process **requires no energy** - it is like diffusion in this sense; molecules only pass along the concentration gradient. This describes how lipid-insoluble molecules like glucose and amino acids cross the cell membrane. This type of carrier-mediated transport is called **facilitated diffusion**.
