  • Cellular Transport: Understanding Nutrient Movement in Cells
    The movement of nutrients in cells is called cellular transport.

    This is a broad term that encompasses several different mechanisms, including:

    * Passive transport: Movement of substances across the cell membrane without requiring energy. This includes diffusion, osmosis, and facilitated diffusion.

    * Active transport: Movement of substances across the cell membrane that requires energy. This is often used to move substances against their concentration gradient.

    * Endocytosis: The process of taking in large molecules or particles by engulfing them in a membrane-bound vesicle.

    * Exocytosis: The process of releasing large molecules or particles from the cell by fusing a membrane-bound vesicle with the cell membrane.

    So, while "cellular transport" is the overarching term, specific types of transport within cells can also be referred to by their individual names.
