🧪 Cell Homeostasis Virtual Lab (Osmosis)

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What happens to a plant cell when it is watered?

Back

When a plant cell is watered, water enters the cell through osmosis, causing the cell to swell and become firm, which helps the plant stand upright.

Front

What occurs when a plant does not receive enough water?

Back

When a plant does not receive enough water, water exits the cells, causing them to shrink and the plant to wilt.

Front

What is the purpose of a control group in an experiment?

Back

The purpose of a control group is to provide a standard for comparison with the experimental group.

Front

What material were the model cells made of in the lab activity?

Back

The model cells were made of dialysis tubing.

Front

Define diffusion.

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane is a barrier that allows certain substances to pass through while blocking others.

Front

How does temperature affect the rate of diffusion?

Back

Higher temperatures increase the energy of particles, leading to a faster rate of diffusion.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What role do aquaporins play in osmosis?

Back

Aquaporins are specialized proteins that facilitate the rapid transport of water across cell membranes.
