The bilipid layer of the plasma membrane:

Back

provides a boundary between the cells and its surroundings, provides communication with surrounding cells, transports substances into and out of the cell.

When a red blood cell is placed in a hypertonic solution, it will:

Back

undergo plasmolysis

Front

This process doesn't require any energy from a cell: active transport, passive transport

Back

passive transport

Front

The diffusion of water through a membrane is called:

Back

osmosis

Front

Facilitated diffusion is often used to transport: substances such as glucose and sodium

Back

substances such as glucose and sodium

Front

This process requires energy from a cell: facilitated diffusion, sodium-potassium pump, diffusion, osmosis

Back

sodium-potassium pump

Front

Diffusion is the movement of a substance

Back

from an area of high concentration to an area of low concentration

Front

A substance that moves down the concentration gradient uses:

Back

passive transport

Back

somatic cells

Front

A student can study a karyotype to learn about the: the process of binary fission, the age of an individual, medical history of an individual, chromosomes present in an individual's cells
