Question

what is cellular transport?
the process of transporting cells to a new location in the body
the movement of substances across a semipermeable cell membrane
a state of balance among all the body systems needed for the body to survive and function correctly
the diffusion of molecules without a semipermeable membrane

Explanation:

Cellular transport specifically refers to the movement of substances (such as ions, molecules) across the cell membrane. The cell membrane is semi - permeable (allows certain substances to pass through while restricting others).

• The first option is incorrect as it refers to the movement of whole cells, not the transport of substances across the cell membrane which is what cellular transport is about.
• The third option describes homeostasis (a state of balance in the body), not cellular transport.
• The fourth option is incorrect because cellular transport occurs across a semi - permeable membrane. Diffusion without a semi - permeable membrane is just simple diffusion in an open system (not cellular transport).

Answer:

The movement of substances across a semipermeable cell membrane.
