Detailed explanation-1: -Large polar water-soluble chemicals, such as sugars, however, do not diffuse through the membrane. Certain relatively large water-soluble molecules cross the cell membrane using carriers. Carriers are membrane proteins that complement the structural features of the molecules transported.

Detailed explanation-2: -There are many ways of transporting substances through the cell membrane. Some of these ways are active transport, passive transport, osmosis, and diffusion.

Detailed explanation-3: -Diffusion is an important process in human physiology. Specifically, diffusion is the mechanism of movement of oxygen, nutrients and other molecules across the capillary walls and the movement of other molecules across membranes.

Detailed explanation-4: -Simple diffusion. Facilitated diffusion. Osmosis.
