Of the two basic structures of an angiosperm plant, roots are described as having the more straightforward function, while shoots have more complex functions. Evaluate and explain why this is true
What will be an ideal response?
Roots have essentially one job: to grow (mostly underground) toward water and minerals and absorb those substances. Conversely, shoots must differentiate into structures with many jobs. Shoots must differentiate into leaves specialized for photosynthesis. They must also differentiate into stems, which have tissues needed for transport of materials and which support the plant too. Shoots must also produce flowers for reproduction of the plant.
