What process is it called when cells move materials out and into the the enviorment?

The process by which cells move materials in and out of their environment is called "transport." This includes two main types: passive transport, which occurs without energy input (e.g., diffusion and osmosis), and active transport, which requires energy to move substances against their concentration gradient. Additionally, processes like endocytosis and exocytosis are involved in the uptake and secretion of larger molecules or particles.
