Cell Processes Review

Front

What is diffusion?

Back

Diffusion is the movement of small molecules from an area of higher concentration to an area of lower concentration across a cell membrane.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane using energy, usually against a concentration gradient.

Front

What is engulfing in cell processes?

Back

Engulfing is a process where a cell surrounds and takes in large particles or other cells.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water and shrink.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to gain water and swell.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy by the cell.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce their own food (glucose) and oxygen.

Front

What happens to a cell in a hypotonic solution?

Back

When placed in a hypotonic solution, the cell swells (gets bigger) due to the influx of water.
