11.Growing young plants are supported structurally but are also flexible.  Which of the three types of ground tissue cells ? parenchyma, collenchymas, or sclerenchyma ? could best provide support without making the plant rigid?

Collenchyma- this refers to a cell type that is towards the stem edges that are held together by a glue-like substance called suberin (from greek 'kolla'- for 'glue')- this adds structural support without rigidity (sclerenchyma are known as stone cells, and add much rigidity, whereas parenchyma is just general storage cells).
