Cell migration. Cell migration is a central process in the development and maintenance of multicellular organisms. Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in particular directions to specific locations. Errors during this process have serious consequences, including intellectual disability, vascular disease, tumor formation and metastasis.
This is called passive transport. Active transport therefore is the movement of a substance or substances against its concentration gradients. This usually happens when the cells need high concentrations of molecules like when glucose is transported to the intestines and when mineral ions are transported to the roots of plants.
