There's facilitated diffusion, where proteins channel in molcules; then there's active transport where the cell uses energy to bring in molecules that are to large or a different chemical configuration.

Which type of epithelial tissue is used in areas where diffusion is a main function?

Diffusion occurs across simple epithelial tissue. These are only one layer.


What transport mechanism do one celled colonial and simple multicellular organisms rely on?

These organisms use simple diffusion as a transport mechanism.This is possible because of the small size of the organisms. Diffusion is effective over small distances but as size increases it becomes less and less efficient.


Is diffussion transformation from high concentration to low concentration?

Yes, simple diffusion/passive diffusion is the movement of a particle from an area of high concentration to one of lower concentration.


What are the examples of simple diffusion?

Examples of simple diffusion include the movement of oxygen and carbon dioxide across the cell membrane, as well as the movement of small nonpolar molecules such as ethanol and urea. This process does not require any energy input and occurs down a concentration gradient.


An example of passive transport process is?

One example of a passive transport process is simple diffusion, where molecules move across a membrane from an area of higher concentration to an area of lower concentration without the need for energy input.


The simple tense of verb is called?

There are two simple tenses past simple and present simple.They are called simple tense because they have one main verb no auxiliary verb.present simple -- I walk to school.past simple -- I walked to school yesterday.


Does facilitated diffusion require ATP?

In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
