Front

What is osmosis?

Back

Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What type of transport does not require energy?

Back

Passive Transport is the type of transport that does not require energy and occurs when solutes move with the concentration gradient.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell.

Front

What is active transport?

Back

Active transport is the movement of materials against the concentration gradient, requiring energy in the form of ATP.

Front

What is the role of ATP in active transport?

Back

ATP provides the energy needed for active transport to move substances from areas of low concentration to areas of high concentration.

Front

What occurs when salt is poured onto eggplant?

Back

When salt is poured onto eggplant, water moves out of the eggplant cells, causing the cells to shrink.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, leading to water moving out of the cell.

Front

Define isotonic solution.

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance across a space, which drives the movement of substances during diffusion and osmosis.

Front

What is diffusion?

Back

Diffusion is the passive movement of particles from an area of higher concentration to an area of lower concentration.
