. One method is that transport proteins in the cell membrane "pick up" molecules from outside the cell and carry them in, while using energy in the process. A second method is that the cell membrane surrounds a particle and takes it in.
Osmosis is one way and the other way is because diffusion proceeds until it is reached equal Librium.
Osmosis and diffusion are ways that cells move things by active transport.
Primary active transport: uses ATP to directly transport materials across the membrane.
e.g. Na+/K+ ATPase
Secondary active transport: uses an established concentration gradient to transport materials across the membrane (concentration gradient set up at expence of ATP or other forms of energy).
e.g. Na+/Glucose symporter, Na+/H+ antiporter
pie is good
One way is the ER (Endoplasmic Reticulum) carries the substances around the cell. I do not know two though.
Two general ways cells move things by active transport include solute pumps and vesicular transport.
Cells can move things by active transport by engulfing, and protein transport
Just guess
engulfing

I believe it's active transport. active transport is correct.
Active transport is when cells use energy to move things through a cell membrane.Passive transport is when the cell uses no energy to move materials.Active - Specifically uses energy and through a cell membranePassive - Specifically uses no energy and materials
passive transport and active transport
Active transport requires the use of ATP because in active transport things move against the concentration gradient. Usually there is a protien pump (which is a form of a transport protien) that does this.

passive transport and active transport
Life would be very difficult and processes would drag if cells were to use active transport to move every substance to its destination.
Active transport requires the use of ATP because in active transport things move against the concentration gradient. Usually there is a protien pump (which is a form of a transport protien) that does this.
Both facilitated transport and active transport move things in and out of the cell. Both movements also depend on the concentration gradient.
active transport
Active transport requires energy for the organism to move things where as passive transport just relies on the net movement of things without the organism interfering.
Materials can move in and out of animal cells through one of two reasons: Passive transport or active transport. Passive transport happens naturally and requires no energy on the part of the cell. It usually happens through osmosis, diffusion, or facilitated diffusion. Active transport involves endocytosis, exocytosis, or molecules moving from a low concentration to high concentration. Active transport requires energy.
