Two types of passive transports are?

Answer 1

PASSIVE TRANSPORTS ARE OF TWO TYPES.

1)SIMPLE DIFFUSION

2)FACILITATED DIFFUSION

1)SIMPLE DIFFUSION:-diffusion of water and dissolved gas is simple. when concentration on both sides of membrane becomes the same,it stops.

2)FACILITATED DIFFUSION:-this also occurs along concentration gradient with help of carrier molecules.

Answer 2

1. Simple diffusion, where molecules move across a membrane from an area of high concentration to low concentration without the need for energy.
2. Facilitated diffusion, where specific molecules are transported across a membrane through protein channels or carriers without the need for energy.
