1. Simple Diffusion - obeying general principles of diffusion - a non-energy-utilising process
2. Facilitated Diffusion - requires carrier molecules or channel forming molecules for necessary diffusive transport.
1. facilitative diffusion-transport proteins provide a pathway for certain molecules to pass 2. osmosis-the passive transport of water across a selectively permeable membrane 3. diffusion- the net movement of the particles of a substance from where they are more concentrated to where they are less concentrated.

cell membrane is a lipid bi-layer which allows only fat soluble sunstances to pass through and the remaining essential materials pass with the help of carrier protien..so on this basis the transport is of two types(1) active transport: Active transport uses energy(2) passive transport : does not use any energycheck it out : active-transport
Passive transport is when molecules pass freely through the membrane moving from the higher concentration area to the region of lower concentration. Three examples of this are diffusion, osmosis, and active transport.
Active transport requires energy, passive transport just happens. If there is more of a certain molecule on one side of a membrane than the other, molecules that CAN fit through the membrane will do, so the concentration will even itself out. No work has to be done to achieve this. SO when you breathe in, oxygen just diffuses across from the air into your blood, because there's plenty of it in the air. But if a plant needs to get say magnesium from the soil (which it needs to make chlorophyll) then it is not going to get much by diffusion, because there's not much in the soil and probably more in the plant. It will need to use active transport ie a protein in the cell wall will pick up the substance wanted and flip it into the cell, and this costs the cell some energy.
It is passive because it does not require energy when moving molecules. It is passive because it does not require energy when moving molecules. There is both active and passive transport. If it is going against the concentration gradient it is active transport. If it is not acting against the concentration gradient it is passive transport.
I know 2 of them are active and passive
1. Facilitated Diffusion 2. Filtration 3. Osmosis

The 2 transporters of cellular energy are passive and active transport.
There are seven types of passive voices 1 General Passive 2 Modal Passive 3 Journalistic Passive 4 Double object Passive 5 + ing Passive 6 + going to Passive 7 + want to Passive By H.K.Dalugama hkdalugama@yahoo.com

i) active transport, ii) passive transport, and iii) diffusion. Answer 2 Above given are processes of transport not factors . Factors include 1: concentration gradient 2 : Temperature , 3 :Surface area .
The inter-membranous transport occurs in two ways: 1) Active Transport: occurs against the concentration gradient, Expenditure of energy occurs. 2) Passive transport: Refers to phenomena wherein transfer occurs along the concentration gradient i.e. from high concentration to low concentration, without any expenditure of energy.

Basically they are of 2 types 1) Active filter - For low voltage network 2)Passive filter
