Question

how the substances are transported through the plasma membrane of a cell?​

Answer 1

Answer:

A membrane can allow molecules to be passively transported through it in three ways: diffusion, osmosis, and filtration. Diffusion: Sometimes organisms need to move molecules from an area where they are highly concentrated to an area where the molecules are less concentrated.

Answer 2

Answer:

Transporting substances in plasma

Plasma is made primarily of water. Many of the molecules the body needs to transport, such as urea , carbon dioxide and glucose, are soluble in water. This means that a large number of substances can be transported around the body in plasma at any one time.
