Question
Why a proper system of transportation is essential in plants?
✓
Answer
Plants are autotrophic. They take in simple substances in the form of inorganic compounds from their environment. CO2 is taken from atmosphere by leaves for photosynthesis. From soil raw materials like N, P and other substances are absorbed by roots. $\rightarrow$ If the distances between soil contacting organs and chlorophyll containing organs are small, energy and raw materials can easily diffuse to all parts of the plant body. $\rightarrow$ But if these distances become large, then diffusion processes will not be sufficient. $\rightarrow$ So, in higher plants to provide raw materials in leaves and energy in roots, a proper transportation system is essential.
