Active transport 
The net movement of larger particles across a partially permeable membrane against the concentration gradient from an area of lower concentration to an area of higher concentration, requiring energy from ATP and molecule specific protein transporters
View source
Two examples of active transport are:
Root hair cells uptake the water and mineral ions needed for plant growth. They use energy from respiration to actively transport the ions against the concentration gradient and into the cell.
Humans sometimes use active transport to absorb nutrients (such as amino acids and glucose) from the small intestine.
