Homework Answers
Simple diffusion
A non water molecule moves down it's concentration gradient, without the help of a carrier molecule or energy input.
Osmosis
Your potted ivy plant is wilted, but perks up after you water it.
Water moves into a red blood cell, without the help of proteins.
Phagocytosis
The cell captures and engulfs large particles.
Active transport
This type of membrane transport moves substances through membrane proteins and requires energy.
explanation
In passive transport, there is no need for ATP. But in active transport, ATP is necessary for transporting the particles across membrane.
hope it helps.

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...
