During active transport the water inside the cell is used to transport substances throughout the cell. Passive transport uses the cell’s cytoplasm to move substances around the cell.
|
|
|
Passive transport moves substances throughout the cell without using the cell’s energy and active transport moves substances using the cell’s energy.
|
|
|
Active transport moves substances from higher concentrations to lower concentrations and passive transport moves substances from lower concentrations to higher concentrations.
|
|
|
Passive transport moves substances that are too large to get through the cell membrane by forming a vesicle inside the cell and active transport forms the vesicle on the outside of the cell.

Detailed explanation-1: -Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Detailed explanation-2: -Active transport may be primary or secondary. A primary active transport is one that uses chemical energy in the form of ATP whereas a secondary active transport uses potential energy often from an electrochemical potential difference.
Detailed explanation-3: -Passive transport moves materials through a cell membrane without using energy while active transport uses energy to move materials through a cell membrane. They are both moving materials through the cell membrane.
