Question : Answer question numbers (a) - (d)on the basis of you understading of the followingparagraph and the related studied concepts :Plant transport systemswill move energy stores from leaves and raw materials from roots. These two pathways are constructed as independently organised conducting tubes . Onethe xylem moves water and minerals obtained from the soil. The other, phloem transports products of photosynthesisfrom the leaves wherethey are synthesised to other parts of the plant. Unliketransportin xylem whichcan be largely explained by simple physical forces, thetranslocation in phloem is achieved by utilising energy.(a)Why is the need for transport system in plants ?(b) What are the components of tissues involved in transportation in plants ?(c)In what form is thephotosynthetic produce transported and stored ?(d)Though transport in xylem is mainly due to physical forces, translocation in phloem uses energy. Explain .
