If a multicellular organism has no transport system, why will its distant cells be affected?
Answer and explanation
Correct answer: They will not directly receive enough materials from the outside environment
The governing concept is transport in multicellular organisms. As body size increases, many cells lie far from the external environment and cannot obtain oxygen, water, nutrients, or remove wastes efficiently by diffusion alone. A transport system carries materials between exchange surfaces and distant tissues. Without it, those cells become deprived and wastes accumulate, impairing normal function. Therefore option A is correct; the other choices do not follow from the absence of transport.
