Questions and Answers

What happens when the concentration of substances on both sides of the membrane is equal?

The processes of diffusion and osmosis occur, and equilibrium occurs.

How does a healthy plant maintain balance?

By allowing water to enter and exit its cells in equal quantities.

What happens to a plant when more water exits its cells than enters?

The inner parts of the cell shrink, the plasma membrane shrinks away from the cell wall, and the plant withers.

What are the two types of passive transport?

The two types of passive transport are diffusion and osmosis. Signup and view all the answers

What is diffusion?

Diffusion is the process of transferring substances across the plasma membrane from an area of high concentration to low concentration without the need for energy. Signup and view all the answers

How does osmosis occur?

Osmosis occurs when water molecules move from an area of higher concentration to an area of lower concentration through a semi-permeable membrane. Signup and view all the answers
