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?


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.
