Cell Transport & Scientific Data

Front

What is the energy source used in active transport?

Back

ATP

Front

Define selectively-permeable membrane.

Back

A membrane that allows certain substances to enter and leave the cell.

Front

What process occurs when a gummy bear is placed in salt water and loses mass?

Back

Osmosis.

Front

Why are diffusion and osmosis important for cells?

Back

They allow cells to take in materials/substances without using energy.

Front

During osmosis, which direction do water molecules move when a cell is placed in a hypertonic solution?

Back

Out of the cell, causing the cell to shrink.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively-permeable membrane.

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy, while active transport requires energy.

Front

What happens to a cell in a hypotonic solution?

Back

Water moves into the cell, causing it to swell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of the cell.
