Active transport in cells is a necessary biological and genuine process that occurs in all biological systems, including plants, animals, and humans. This process is critical for maintaining life because it transports various essential materials in the eukaryotic cells, tissues, and organs. Water, hormones, gases, mineral nutrition, organic material, and other important …
