Question

The movement of ions and other atomic or molecular substances across cell membranes without the need for energy input is known asdiffusion.isotonic movement.passive transport.voltage.

Answer 1

There are two types of transport in the cell - passive transport and active transport. In passive transport, the movement of substances is done without the need for energy. In active transport, the movement of substances is done with the need for energy. Examples of passive transport are diffusion and osmosis. Examples of active transport are voltage-gated channels, sodium-potassium pump, ATP synthase, etc.

ANSWER: passive transport
