The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules. Passive transport can only move molecules from a region of higher concentration to lower ...

Active transport is a process that moves molecules against a concentration gradient. The process requires energy. For plants to take up mineral ions, ions are moved by active transport into root hairs ...

Researchers at New York University and the University of Chicago have developed artificial, fully synthetic cell-like structures that autonomously ingest, process, and push out material, recreating an ...
