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.

Give two differences between active transport and passive 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.
What are the different types of passive 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. (out of a sophomore Biology book)... hope this helps <3
What are three ways molecules can cross the cell membrane?
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
What is the importance of passive and active transport to the cell?
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.
What are 2 situations which active transport would be required?
well if the active transport was not used it would have to use the passive transport. the meaning of not using the active transport because if you use the active transport in one case it would burst
What are the 3 methods of passive transport?
1. Facilitated Diffusion 2. Filtration 3. Osmosis
What are the 2 transporters of cellular energy?
The 2 transporters of cellular energy are passive and active transport.
What factors affect bulk transport?
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 three types of cell transport in a cell and how the materials of each are moved in and out of the cell?
I know 2 of them are active and passive
What is the meaning of the passive transport?
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.

What is the active transport and passive transport?
Active transport is the movement of a substance across a cell membrane against its concentration gradient and Passive transport means moving biochemicals and other atomic or molecular substances across membranes.
