Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen
