Unit 2 Biology- FUNCTIONING ORGANISMS SAC-‘Essay on transport systems’ “Transport systems play an essential role in the survival of flowering plants and mammals” Transport systems play an essential role in the survival of flowering plants and mammals. These organisms rely entirely on the transport of water, oxygen and nutrients to every cell. To supply these products at a rate the organisms demand to sustain life, they have developed a specialised transport system. Simple diffusion from …showed first 75 words of 1009 total…

The slow rate of solutions moving in the xylem and phloem is much slower than the rate of blood flow in mammals and this reflects the greater metabolic needs of mammals. Without transport systems these organisms would cease to exist therefore transport systems are essential for the survival of flowering plants and mammals.
