For a mineral nutrient to get to the leaves, it must make it to the plant xylem. Which layer would the
  nutrient need to traverse in a dicot? What will be an ideal response?
 
 

Question 2

Imagine you were building a plant. You wanted a particular tissue to be somewhat rigid but capable
  of rapid growth. What tissue type would you pick? What will be an ideal response?
 

Answer to q. 1

The nutrient would enter the plant via the epidermis. Next, it would move through the cortex.
Following this it would cross the endodermis and pericycle. Finally it would enter the xylem.

Answer to q. 2

Parenchyma are capable of rapid growth but are not rigid. Sclerenchyma are rigid, but dead at
maturity and therefore cannot grow. The best choice would be collenchyma, which have thick walls
for rigidity but are alive at maturity and can grow.
