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