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.

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.
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 is the movement of solute from a region of high concentration to one of lower concentration?
Diffusion; a form of passive transport.
What Small droplets of liquid can pass through a cell membrane by the process of?
One method of movement across the membrane is by diffusion, which is related to osmosis.
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.
What are the examples of simple diffusion?
Osmosis is one of the easiest-to-understand examples of diffusion. Past that, you will need to define 'simple'.

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.
Explain osmosis diffusion passive transport and active transport?
Osmosis is the diffusion of water molecules through a semi-permeable membrane. Diffusion is a passive transport that goes from a higher concentration area to a lower concentration area.Passive transport means that there is no energy required to move it.
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.

Simple Squamous Epithelial Tissue forms the surface of the alveoli

What is one sixteenth in simplest form?
This fraction is already in simple form.
